Introduction to Subtraction Number Bonds

In Grade 1 students begin to learn how to solve subtraction problems using a visual tool called a number bond. A number bond shows the relationship between a whole number and the parts that make it up. When we talk about Subtraction Number Bond, we are focusing on how a whole can be broken into two parts, and how taking one part away leaves the other.

What Is a Number Bond?

A number bond is a simple diagram that represents a number and its addends. For example, the bond for 7 might show 5 and 2 branching from the whole. This visual helps children Dive into Singapore Math concepts that emphasize understanding over memorization.

Why Use Subtraction Number Bonds?

Subtraction number bonds help young learners see the connection between addition and subtraction. By viewing a whole as two parts, students can Take from Ten Strategy for Subtraction more easily, especially when the whole is ten. This strategy builds confidence and speeds up mental math.

How the Take from Ten Strategy Works

When subtracting from a number like 10, 20, or 30, the Take from Ten Strategy for Subtraction suggests breaking the whole into a ten and the remaining part. For instance, to solve 10 – 6, students think of 10 as 6 + 4 and then recognize that the missing part is 4. This method is especially effective in Grade 1 because it uses familiar tens.

Step‑by‑Step Example

Let’s solve 10 – 3 using a subtraction number bond.

  1. Draw a circle for the whole number 10.
  2. Place one branch for the known part, 3.
  3. The other branch will be the unknown part, which we need to find.
  4. Since 3 + ? = 10, the missing part is 7.
  5. Therefore, 10 – 3 = 7.

This visual approach makes the subtraction process concrete and reduces errors.
