Number bonds are a mathematical concept that helps students understand addition and subtraction. They are also a helpful tool for teaching mental math. Number bonds are created when two numbers are added together to make a certain sum. For example, the number bond for 7 would be made up of the numbers 3 and 4 because 3 + 4 = 7. Number bonds can be represented visually by using a number line or a hundred chart.
Number bonds can be used to teach a variety of math concepts such as addition, subtraction, place value, and mental math. When teaching addition and subtraction, number bonds can help students see the relationship between addition and subtraction. For example, if a student knows that 7 + 3 = 10, then they can also conclude that 10 - 3 = 7. This understanding is crucial for solving word problems. In addition, number bonds can help students understand place value. For instance, if a student knows that the number bond for 7 is 3 + 4, they can also understand that 7 is in the tens place because 3 + 4 = 10.
Number bonds can be a helpful tool for teaching mental math as well. By using number bonds, students can quickly add or subtract small numbers in their head. For example, if a student sees the number bond 7 + 3 = 10, they can immediately subtract 3 from 10 in their head to get 7. This is a valuable skill for students to have when they need to do quick calculations in their head.

Topic Description:
Understand how number bonds can be used to visualise that parts can be combined to form a whole. Understanding decomposition of numbers to 10 through number bonds, connecting number bonds to numerical expressions, understanding both the addition conditions of “putting together" and “adding to”, exploring word problems.
Learning Targets:
I know that numbers can be broken down into parts.
I can break numbers apart using objects or drawing models like number bonds.
I can write equations to show how I break numbers apart.
I can find two numbers that make ten.
I can solve addition problems
