Adding Multiple Numbers Practice

Adding 3 One-Digit Numbers

Add three single digit numbers together (like 4 + 7 + 3).

Student Tips:

• Look for numbers that make 10 first: 4 + 7 + 3, find 7 + 3 = 10, then 10 + 4 = 14
• Add the first two, then add the third: 4 + 7 = 11, then 11 + 3 = 14
• Use your fingers or draw dots to help count
• Check your work by adding in a different order

Teaching Instruction: Emphasize “make 10” strategy with manipulatives. Use three different colored groups of objects. Practice finding pairs that make 10 within the three numbers. Show that order doesn’t matter (commutative property).
