Addition Worksheets:Spaceship Math
These addition worksheets are similar to the RocketMath, Wolf Swamp or Mastering Math Facts addition worksheets used at many schools. These are typically one minute, timed tests (follow the "Timer" link off the home page.)
If you are just getting started with math facts, this is the first step! These one minute addition worksheets gradually introduce math facts until the entire addition table has been covered. Each set of worksheets has four variations with answer keys. The final worksheets in the set incorporate all of the facts, which make for a great review of the addition facts table. These worksheets are similar in structure to the Mad Minute or Rocket Math programs used by many schools to introduce math facts in first grade or kindergarten.
