What This Standard Means
What Students Need to Do
- Students break a set of up to 10 objects into two parts. They show several pairs that combine to make the given total.
What Mastery Looks Like
- A student can split a set in several correct ways and record the two parts with drawings or numbers. For 6, the student might show 0 + 6, 1 + 5, 2 + 4, and 3 + 3.
Common Misconceptions
- Students may think both parts must be greater than zero, so they leave out pairs with zero. They may treat 2 + 5 and 5 + 2 as unrelated. Some splits do not total the given number.
How to Assess It
- Give each student seven counters. Say, "Show and draw every way you can split seven counters into two groups."

Ways to Teach It
Give pairs seven counters and two paper plates, then have them move counters between plates and record each split.
Show 6 as 1 and 5, then ask, "How can you split 6 another way, and how do you know?"
Students draw a 0 to 10 card and fill a part-part-whole mat with three different pairs before earning the card.
Set out nine toy apples and two baskets, then list the ways a grocer could divide the apples between them.
