Circle Math Facts Worksheets

Need Another Spin on Math Facts? Try These New Circle Worksheets!

There are never too many ways to practice math facts, and these new circle worksheets are another approach to learning how numbers are related to each other in addition, subtraction, multiplication or division groups!

Each circle collects a set of math facts related to a single number, for example the multiplication worksheets all have a common value, so each circle is essentially a set of multiplication facts. You can go around the circle and solve each fact to help emphasize strategies like skip counting or repeated addition to learn multiplication. Alternatively, some of the worksheets have the facts in a random order around the circle which requires students to think a bit more to solve the whole set.

The addition, subtraction and division worksheets all follow a similar pattern. When you’re working to establish the relationships between similar sets of math facts for these operations, you’ll find these worksheets to be another useful tool, and I hope a visually interesting one as well!

If you have an idea for more worksheets, let me know in the comments. And as always, I appreciate your sharing these (or any other worksheets) with other parents or educators who would find them useful!

I hope your autumn is off to a great start!

Printable Blank Coordinate Planes

New Printable Coordinate Plane PDFs!

Coordinate planes are a staple of linear algebra, and having ready access to printable versions of these tools can be a big help when students are learning how to graph equations. I’ve had a meager collection of printable coordinate planes on the site for some time, but admittedly they’ve fallen into some dis-repair. Converting the older coordinate planes into PDF format and adding new homework templates has been on the to-do list for some time, and I’m pleased to announce they are finally all live on the site.

If you visit the new coordinate plane page you’ll find the not-quite lost single page, 4 quadrant coordinate planes that have lurked in a corner of the graph paper gymnasium for a while, ever hopeful that someone would find them there and ask them out to dance. These lonely grids are now happily socializing with many of their peers, including inch and centimeter dimensioned coordinate planes, planes with quadrant labels, and a new set of coordinate planes that are numbered and dimensioned along the edges of the grid instead of directly on the axis lines.

Also, you’ll find a completely new set of coordinate plane homework templates that are setup for single problem, two problem, four problem or six problem work. Print the size you need depending on how much work space or grid space you need to solve your particular problems, and those homework assignments will look super sharp.

You can check out all of the new pages at the link below, and if you have suggestions for more layouts please leave a comment!

Finally, I didn’t want the graph paper page to feel too left out, so when I also added dot paper and isometric dot paper to the party there. If you’re looking to do some 3D sketches, the isometric dot paper is a great tool, but either format can also be used for a round of the old ‘dots and boxes’ paper and pencil game that kept me and my girlfriend occupied during 10th grade history lectures…

Thank you for 10 Years!

Thank You for 10 Amazing Years!

Ten years ago, I sat down with my oldest daughter who was struggling with her 2nd grade math facts, and I started making practice worksheets using a few Python scripts. When several parents asked me to share those worksheets online, DadsWorksheets.com was born.

Over the course of the last decade, the number of worksheets has grown, and I’ve had the chance to build charts and calculators and games that have all played a role in helping my kids, and hopefully yours, learn math.

There are over 8,000 worksheets now and almost 20 million visitors have stopped by looking for help with multiplication or word problems or Roman numerals or some other math topic, each of which is tied to memories in my basement office with my own kids. It’s been a lot of fun for me, but I am also humbled by how many people have visited. All of your support and encouragement has definitely added to the joy of building DadsWorksheets.

My oldest daughter is entering college at University of Arizona next year, and my youngest daughter is starting 2nd grade, so the cycle in many ways has come full circle. I’m thankful for my four amazing girls, and to all of the people I’ve had a chance to interact with since this site first started, and I’m excited to see what the next ten years brings!

Summer Math Worksheet Updates

Summer Updates Before Back to School!

I hope everyone is having a great summer and getting ready for the 2018-2019 school year!

It’s been a busy couple of months here, but there’s always time for a few quick math worksheet tweaks! It turns out there were a few spelling errors in the inches measurement worksheets and the metric measurement worksheets that needed to be fixed up. If you haven’t seen these worksheets, they’re great on-paper practice for kids learning to use either an imperial or metric ruler measure length.

The two youngest daughters are headed to a new school that teaches (of all things) Latin along side world history, so there’s ongoing interest in Roman numerals around the house these days. I already have some great Roman numeral worksheets and an interactive Roman numeral converter, but this round of updates includes a couple new Roman Numeral charts.

Finally, multiplication is always a hot back-to-school topic, and while we’re almost past mastering these facts ourselves, I’ve had some request for larger charts. If that’s you, please check out the new 30×30 and 50×50 multiplication charts.

We still have a week left before school starts, and we’re reviewing math facts like crazy, and I’m sure the girls are looking forward to the classroom so they can escape their crazy dad… What are you doing for back to school math practice? Let me know in the comments!

DadsWorksheets Connect App

How Can Teachers REALLY Connect with Parents for Math Practice?

While there is a lot of deeper math content on this site, many visitors come here looking for help with core math facts. That includes a huge number of teachers who are tasked with getting a class full of rowdy third graders through their multiplication tables by the end of the school year. This requires not just organization in class, but a lot of support from parents at home.

That’s why I built the DadsWorksheets Connect web application. Using this tool, a math teacher can create a list of class students, assign a pre-defined sequence of worksheets (for example, regular subtraction practice or the SpaceShip Math Multiplication set), keep track of class progress, and send updates home to parents with reminders to practice a specific math worksheet that will help their child’s success in the classroom.

Please check out this video I put together for more details (right after the obligatory silly intro, of course!)

…then give it a try yourself at the link above.

If you’re a teacher, I hope you’ll give it a spin and let me know your thoughts. And if you’re a parent, please share it with your teacher or even just setup your own account (you’re a teacher, just with a much smaller class!). I’ll be adding more parent-specific capabilities soon, including the ability to setup worksheets and reminders for at-home goals!

Visual Multiplication Worksheets

Multiplication Gets Visual!

Teaching multiplication can be a tricky endeavor. It really is one of those first arithmetic topics that move very quickly past finger (or toe) counting, so unless your little mini muffins have a truly solid conceptual understanding of what’s going on, much of the dinner-time discussion of this operation quickly deteriorates into what I’m sure to little ears sounds like a stream of random and arbitrarily large numbers.

Building arrays out of manipulatives is one way to help make multiplication concepts a little more accessible. So while I’m a huge proponent of memorizing those math facts, sometimes there’s nothing better than a visual aide to tie the idea down and give all that math fact practice a foundation somewhere.

That’s where these new visual multiplication worksheets come in. They’re designed to be the very first worksheets your third or fourth grade student encounters when you’re introducing multiplication, and they’re a great followup to those dinner discussions with rows of peas or Brussel sprouts, which may or may not get your kids begging to do math worksheets… You never know. Anyway, by showing an array of small wooden blocks and asking students to think about rows and columns, they provide a bridge between strategies like skip counting and multiplication.

Visual Multiplication Worksheets

Each of the arrays is a distinct photo of some small wood blocks, so building these was a bit of an art project. I hope you enjoy them, because Dad won’t be making too many other similar worksheets like this any time soon!

Regardless, I hope you’ll give them a try if you’re just starting on your multiplication facts. When you’re ready for more, be sure to check out the multiplication charts, multiplication tables, and of course all the multiplication fact worksheets as well!

Rounding Worksheets

Rounding Worksheets for the Naughty Number Nine

I’ve had quite a collection of rounding worksheets and rounding charts on the site for some time, and they’ve provided great practice for my two oldest daughters. Just recently, however, my third grade daughter started a unit on rounding at school and an inappropriate right turn on the rounding round-a-bout had me pulling over to revisit these worksheets.

The steps to round numbers are pretty easy. Find the digit that corresponds to the place value you’re rounding, so for example if you are rounding to the nearest hundred, find the hundreds place. We typically call that the “target digit” or “target number” here. Then look for the next smallest place value just to the right of the target digit. If that second number is five or greater, round the target digit up, otherwise leave it alone, then zero out all the smaller place values. Sometimes you’ll hear the basic rounding advice rhymed as, “Five or above, give it a shove. Four or less, give it a rest.”

But, sometimes, when the target digit is a nine, we’ve got one teeny extra step that often gets rounded right out of the discussion. If we’re rounding up a nine, that place value actually becomes a zero and the next larger place value gets incremented. In effect, we’re carrying or regrouping that rounding into the next lane. It’s a trivial step, and usually we’ve covered addition with carrying already so it’s an easy point to miss in your explanation of the process.

That is, unless you’ve learned rounding completely algorithmically, which unfortunately, seems to be what poor daughter #3 has done. So we’re back to doing a little bit of number line examples in conjunction with these new rounding worksheets that feature quite prominently potholes on the road in the form of that naughty number nine.

I hope if you’re on the same road these worksheets get you out of the ditch.

Printable Logic Puzzles

Are You Ready for These Logic Puzzles?

Well, the school year is in full swing and we’ve just entered the fall season in the northern hemisphere. Anyone tired of math drills yet?

I’ve had a nice collection of missing number and missing operation puzzles on the site for some time, but given the popularity of the many types of number logic puzzles you probably knew it was inevitable that I’d be making sudoku, magic squares and more at some point. So just in time to save you a entire season of math fact drudgery, I’d like to welcome you to the new logic puzzles page here at DadsWorksheets!

Printable Logic Puzzles

You will find a cool set of puzzles to start things out, including several variations of sudoku. You’ll find really challenging Samurai sudoku puzzles as well as a color sudoku for kids set that is a great way to introduce grade schoolers to puzzle solving as a coloring activity. And while these puzzles are principally targeted at kids, for you Sudoku masters out there I included a set of Evil Sudoku puzzles taken from a list of puzzles with the fewest possible clues that still insure a valid single-solution puzzle.

You will also find magic square puzzles and more as I continue to update this section with math-related puzzles for kids (and kids-at-heart.) Traditional logic word puzzles are coming soon… If you have any more ideas for printable logic puzzles, please let me know in the comments and I’ll see what I can do!

Fraction Worksheets

Amazing New Fraction Worksheets Just in Time for Back to School!

I hope all of you have had a great summer! If you’re just returning to your math drills for the school year, I hope you’ll notice a big change around here at DadsWorksheets! I’ve been busy updating our worksheets starting with switching to PDF files, and a great deal of effort wehnt into giving them a more modern look and feel…

I’m especially pleased with the fraction worksheets… Not only do the new worksheets look amazing, but the answer keys show work with more clarity, adding a few extra steps to the computations to make some of the problems a little easier to understand. You’ll especially appreciate this when working with the multiplying fractions or dividing fractions worksheets, where solving those types of problems can have many steps.

As always, these worksheets show you how to cross-multiply fractions where necessary to get the answer. Cross multiplication is difficult to explain, but having fraction problems that illustrate the steps in the key can be a huge help for kids trying to see where their computations went wrong (or, if you’re an adult, I can tell you from experience they also come in handy more than you might think!)

If you’re starting 3rd, 4th or 5th grade, now’s the time to start learning fraction concepts and these worksheets are a great place to start… I hope you’ll print a few out and let me know what you think in the comments section below!

It’s another great tool for explaining fraction problems and seeing how to solve them!

Printable Hundreds Charts and Picture Puzzles

Great Ways to Use a Hundreds Chart!

A hundreds chart? If you’re wondering why, for good gracious, you’d use one of these to teach counting, or even multiplication, you definitely won’t by the end of this post.

If you’re like us, you probably spend time in the car counting over and over again to 100. After having gone down this road (and many many miles of it with four girls now), I’m starting to believe it’s like staying in only one lane of the highway on a road trip to Puerto Williams, Chile (which, for reference is the southern-most city in the world, and I’m not sure you could even get there by car even if the math worked out somehow.)

So what’s wrong with counting, you ask?

When the kids learn to count orally, they’re often just learning a pattern of words, almost like a song. Oral counting is great, as long as there’s a mental model of number sense to back it up.

That’s where these awesome hundreds charts come in.

Printable Hundreds Charts

A hundred chart provides a visual representation of both quantity, and of the relationships between the numbers in the rows and columns of the chart. You’d be amazing how many kiddos can recite the numbers from one to a hundred in order, but when they’re confronted with reading a number off a page have trouble. We struggled here with the difference between 41 and 14 more times than I care to admit.

So print off these hundred charts, then start with some activities that build real number sense. Here’s a list of things to try:

  • Play the ‘Guess My Number’ game on the hundreds chart.That simple higher/lower game is great practice for reasoning about which numbers are bigger or smaller, and marking previous guesses on the hundreds chart will give younger kids the support they need. Make it competitive by seeing who can guess a number in the smallest number of turns (for adults who need a little extra edge, read up on binary search algorithms.)
  • Roll the chart up into a tube and count around and around and around…Nothing makes it clear that the numbers go in a continuous sequence like rolling a hundreds chart up and counting around the bend.
  • Cut the hundreds chart up, then put it back together again.We have an unending fascination with tape here, so this is always a winner. Print out one of the hundreds charts, cut it up randomly then tell the kid to put it back together again with tape. Bonus points if you time them. A good starter is to do this with one of the color hundreds charts which provides some color-cues to help make the assembly go faster, but you should move on to the black and white charts once the concept is clear.
  • Color in a hidden picture puzzle on the 100s chart.There are a ton of these online, but obviously the best hidden picture puzzles are right here at DadsWorksheets!
  • You can use a hundreds number chart to determine the difference between two numbers.This is a great activity for conceptualizing addition and subtraction. You can use a hundreds chart as a resource when practicing addition facts or subtraction facts as a substitute for finger counting (especially handy when you’re out of fingers.)
  • Play race to one hundred on the chart.You’ll need a game piece (or two if you’ve got more than one kiddo on hand) and a die. Start with both players on number 1, and have each player roll the die then move their piece that many numbers forward on the chart. The first one to get to 100 wins. Try having them only roll a number at the end that lands exactly on 100 to win.
  • You can do skip counting easily on the hundreds chart. A great activity is to print a hundreds chart and color in odds, evens or multiples of 5. Or, color multiple patterns and see where they overlap, a great start on understanding factors of numbers. Skip counting provides an opportunity to begin understanding the properties of certain sequences of numbers (for example, that adding two to an even number always produces an even number, or that multiples of 5 always end in 5 or 0). Even more so than using a multiplication chart to memorize multiplication facts, skip counting also helps kids build the number sense necessary for multiplication.
  • Find prime numbers using the Sieve of EratosthenesOnce you have a student who understands multiplication, division and the idea of prime numbers, you can use a hundreds chart to perform the Sieve of Eratosthenes, which is really simply way to not only introduce primes, but to discover one way that they can be revealed.

Any of these activities work well with the 100 chart or with the 120s charts available at the link as well… You’ll notice sometimes when kids learn what follows 100, it can be a challenge. That’s why some of the Common Core activities work with 120 instead of 100… It’s just a large enough range to get you well into that third place value, and it also fits nicely into some of those times twelve tables that you’ll undoubtably come across soon as well.

Whether you’re building up number sense or just using these number charts as a way to learn your math facts, I hope these new charts help move your math lessons on down the highway just a bit faster… Do you have some other great hundreds chart games or activities? Leave a comment and let me know!
