Use objects to solve word problems related to addition and subtraction that involve unknowns and quantities up to 5.
Clarifications:
Essential Understandings
Concrete:
- Make a set with objects from a given context within 5.
- Join or separate objects and count to determine how many were ‘added to’ the set (Ex: Rich had 1 crayon. Rich found more crayons. He has 4 crayons. How many did he find?) ‘taken from’ the set (Ex: There were 4 apples. Jane ate some of the apples. There are 3 apples left. How many apples were eaten?), or the sum or difference.
- Make a visual representation of a set from a given context within 5.
- Join or separate visuals and count to determine how many were ‘added to’ the set, ‘taken from’ the set.
- Recognize that the numbers in the problem relate to the visuals being utilized.
- Understand the following concepts and vocabulary: add, take apart, take from, subtract.

Category: Access Points
Cluster:
Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from. (Major Cluster) :
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
