## One Big Fibber

No, not “fibbing” the way you’re thinking… More along the lines of adding up lots of numbers. Around 1202 the fellow to the right, a 13th century Italian mathematician named Leonardo Pisano, produced an interesting book describing in detail how to manipulate numbers in columns, much like the way we learn in school (and here at DadsWorksheets.com) to perform the basic math operations.

## Over 3,000 Worksheets and Counting!

After having passed the 2,000 worksheet mark in late September, the site has expanded another 50% to over 3,000 worksheets in less than four months. That’s a rate of approximately 250 worksheets a month, or roughly eight new worksheets a day! If the trend continues, that would put us at 4,000 sheets by the end of the school year, which I’m willing to set as a goal, but only because we’re technically 101 worksheets ahead coming out of the starting blocks…

If you have any requests or ideas for additional worksheets that you think would fit in with the other material here, feel free to post a comment to this post. I’m sure there are lots of great ideas out there and your feedback is appreciated.

Meanwhile, I hope you’ll share the enthusiasm and pass word about the site to parents or teachers whom you think might appreciate the content here. If you have a blog or a web site, a link helps greatly spread the word.

Thanks for your support and see you at 4,000!

## Over 300 New Number Pattern Worksheets!

Number patterns are a great way to revist basic addition and subtraction operations in a different format from the usual math drills. They also illustrate some interesting relationships like 15 minute intervals in hours, intervals of 25 in dollars and the ever-useful mechanics of multiples-of-five that seem to show up in every day life.

It seems like number patterns are increasingly appearing on things like AIMS tests and other placement exams. Include a healthy does of number patterns in your regular worksheet diet and pattern problems will be like striped candy. Or, so I keep telling my eldest.

New number pattern worksheets can be found at the link here…
