Addition using number bonds is a visual strategy that helps students understand the relationship between numbers and the parts that make them up.

To use number bonds to add, students can break down one or both of the numbers being added into smaller parts that add up to the original number. For example, to add 7 + 5, students can draw a number bond with 7 in one part and 5 in the other, and then fill in the missing addend(s) that make the bond complete.

Using number bonds to add helps students develop their understanding of number sense, place value, and basic arithmetic. It also provides a strong foundation for more advanced math concepts, such as algebraic thinking and solving equations.

Making 10 to Add is one of the most important mathematical skills students build in first grade. It gives students a starting place when adding and base 10 becomes a ‘safety’ when students aren’t sure where to start.

1. Use the number bond and add the sums.
2. Do the following sums by making 10.
3. Use the ten to make the following sums easy.
4. See the diagram and add the numbers.
