What This Standard Means
What Students Need to Do
- Students put together and break apart quantities of 10 or less. They show more than one combination with counters, pictures, spoken words, or number sentences.
What Mastery Looks Like
- A student can show several accurate combinations for a given number, such as 5 and 3, 6 and 2, or 4 and 4 for 8. The student can name the parts and explain that the total stays the same.
Common Misconceptions
- Students may count each group correctly but name the wrong total. They may think switching the same two parts makes a new combination, or that numbers must split into equal parts.
How to Assess It
- Give an exit ticket: “Show three different ways to make 9. Use a drawing and numbers for each way.”

Ways to Teach It
Give students eight two-color counters to shake, spill, sort by color, and record each split with a drawing and number sentence.
Prompt: “Maya says 7 can only be 5 and 2. Do you agree? Show evidence and explain.”
Play Make My Number: draw a target card, then build and record two different part pairs for that number.
Place ten crackers on two napkins in different ways, then draw and label three possible splits.
