There are many terms your child will use when learning addition in 1st grade. Let's talk about one -- Number Bonds!

A number bond shows part-part-whole. When learning number bonds, your child might ask you to help them "put together."

Here's an example: Look at these 6 tasty apples! This group has 4 apples. This group has 2 apples. When both groups are "put together," there are 6 tasty apples!

A number bond for these apples looks like this: Part, part, whole. Part, part, whole. See? Number bonds! Using number bonds helps your child develop a conceptual understanding of "composing" or "putting together" numbers.

4 + 2 = 6 and 2 + 4 = 6 is the same as... 6 = 4 + 2 and 6 = 2 + 4.

Now you can help your child with number bonds and putting together!


This video addresses Common Core Kindergarten Standard Operations & Algebraic Thinking: Understanding addition as putting together and adding to, and understanding subtraction as taking apart and taking from.

(K.OA.1) Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g. claps), acting out situations, verbal explanations, expressions, or equations.

(K.OA.2) Solve addition and subtraction word problems, and add and subtract within 10, e.g. by using objects or drawings to represent the problem.
