Max Rescues Robot Friends: Addition Sprint!

About this Grade 2 Addition Drill

Addition is a cornerstone skill that second graders use throughout their entire school day—from splitting snacks fairly at lunch to solving simple story problems in math class. At ages 7-8, students are developing fluency with sums within 20, which builds their number sense and confidence with quantities. This skill strengthens their ability to think flexibly about numbers: they begin to see that 7 + 5 is the same as 5 + 7, and that knowing 6 + 4 = 10 helps them solve 6 + 5. Beyond math class, addition helps children manage real situations like combining their pocket money or figuring out how many toys they have altogether. Most importantly, repeated practice with addition facts at this age frees up mental energy so students can tackle word problems and larger mathematical ideas in third grade without getting stuck on basic computation.

What your student will practice

• Add two single-digit numbers with sums up to 20 with automaticity
• Recognize and use the commutative property (order does not change the sum)
• Use strategies like counting on, doubles, and ten-frames to solve addition problems
• Apply addition facts to solve simple word problems or real-world scenarios

Common mistakes to watch for

Second graders commonly miscount when adding by starting over at 1 instead of counting on from the larger number—for example, solving 8 + 3 by counting 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 instead of starting at 8 and counting up three more. Watch for students who lose track of their count using fingers or who skip numbers. Another frequent error is reverting to the wrong sum when facts haven't been automated yet, like confusing 6 + 5 with 5 + 5. You'll spot this when a child gives different answers for the same problem on different attempts.
