One number can have many structures.
Number bonds help children see that the same whole can be made from different parts.
The number stays the same. What changes is the way the child sees it. That flexibility supports addition, subtraction, place value, mental mathematics, and later multiplication.
A gradual pathway from smaller numbers to 20.
The pages become more challenging gradually, so children can build understanding before moving forward.
See Whole and Parts
Start with completed number bonds and notice how two parts combine to make one whole.
Find the Missing Part
Use the whole and one known part to reason about what is missing.
Make It Another Way
Explore several different ways to compose the same number.
Build Toward 10
Strengthen combinations that make 10 and use 10 as an important number benchmark.
Extend Beyond 10
Continue the same thinking with numbers from 11 through 15.
Number Bonds to 20
Apply part-whole thinking to larger numbers without changing the underlying idea.
There is a reason we spend time making 10.
Seeing 10 as 5 + 5, 6 + 4, 7 + 3, 8 + 2, and 9 + 1 gives children relationships they can draw on again and again.
Later, these relationships support mental addition, subtraction, place value, and efficient calculation.
You do not need to teach a lesson.
Give your child space to build, draw, or think. If a missing part feels difficult, use counters, cubes, coins, buttons, or another simple object.
The goal is not speed. The goal is to help the child see the relationship.
