Max Rescues the Lemonade Stand: Addition Sprint!

About this Grade 1 Addition Within 10 Drill

Addition within 10 is a cornerstone skill for first graders because it builds the number sense foundation they'll rely on for all future math. At ages 6 and 7, children's brains are developing the ability to hold multiple numbers in mind simultaneously—a critical cognitive leap. When students practice combining small groups (like 3 + 4 or 2 + 5), they're not just memorizing facts; they're learning how numbers work together and building mental flexibility. This fluency with small sums helps children solve real problems, from sharing snacks to counting coins at a lemonade stand. Mastery at this level prevents gaps that make later subtraction, two-digit addition, and word problems feel overwhelming. Students who solidify these facts now gain confidence and independence, setting them up for stronger math engagement throughout elementary school.

What your student will practice

• Fluently add two numbers with sums to 10 using fingers, objects, or drawings
• Recognize that addition order doesn't change the sum (commutative property)
• Solve missing-addend problems within 10 using strategies and reasoning
• Apply addition-within-10 facts to solve simple story problems

Common mistakes to watch for

Many first graders count from 1 every time instead of counting on from the larger number—so instead of starting at 7 and counting on 2 more, they recount 1, 2, 3, 4, 5, 6, 7, 8, 9. You'll spot this by watching them use their fingers or noticing they slow down significantly. Others lose track of what they've already counted, especially with larger groups, and recount the same objects twice. Some students also struggle to understand that 3 + 5 and 5 + 3 equal the same amount, treating them as completely different problems rather than seeing the connection.
