Number Bonds Worksheets for Kindergarten
Break numbers into two parts using number bond diagrams.
About Number Bonds
Addition is the process of combining two or more quantities to find a total. It is one of the four fundamental operations of arithmetic and the one children typically learn first. These worksheets progress from concrete representations (counting pictures and objects) to abstract number sentences, building both conceptual understanding and computational fluency.
Number bonds make the structure of addition and subtraction visible. When children see that 7 is made of 3 and 4, they instantly know four related facts: 3+4=7, 4+3=7, 7−3=4, and 7−4=3. This efficiency is foundational to math fluency.

- Find the missing part when one part and the whole are known
- Connect number bonds to both addition and subtraction facts

Tips for Parents & Teachers
Start with objects your child can touch and move — combining two groups of blocks or toy cars makes addition tangible.
Teach the "count on" strategy: start from the bigger number and count up. It is faster than counting everything from 1.
Practice "making 10" — it is the most powerful addition strategy and will serve your child for years.
Use addition in daily life: "You have 3 strawberries and I am giving you 4 more. How many will you have?"
