What This Standard Means
What Students Need to Do
- Students join smaller groups to make a number up to 5 and split a number into smaller parts. They show several combinations with objects, pictures, words, or numbers.
What Mastery Looks Like
- For 5, a student can show 4 and 1, 3 and 2, and 5 and 0 using objects or drawings. The student can explain that each pair makes 5.
Common Misconceptions
- Students may think a number can be split only one way or may leave out zero as a possible part. They may change the total when moving objects into two groups.
How to Assess It
- Give each student five counters. Say, "Split 5 into two groups in two different ways, then draw and label each split."

Ways to Teach It
Give pairs up to five counters and two cups, name a target, and have them place the counters in different cup combinations.
Show five apples beside two baskets and ask, "How many different ways could we put the apples into the baskets?"
Roll a 1 to 5 die, build that number with cubes, split the cubes into two groups, and record each new split.
