Subtraction is a mathematical operation that allows us to find the difference between two numbers. It is the opposite of addition and is very similar, but with a few key differences.

For primary 3 students, it is important to break the concept of subtraction down into smaller steps that are easier to understand. You can start with the visual representation of subtraction using objects or pictures. Ask students to identify the number of objects in each set, and then model subtracting objects from one set to get a new total. This is an important concept as it helps students to understand the subtraction process.

Next, ask students to complete subtraction problems involving single-digit and double-digit numbers. Once students have become familiar with the basic subtraction process, move onto more complex problems. For example, students can start subtracting three- or four-digit numbers and solving subtraction problems with regrouping.

Finally, introduce some fun activities to reinforce subtraction skills. Examples of activities could include creating word problems that involve subtraction, playing games like “If You Take Away”, or even creating their own wall of subtraction problems to practice in the classroom.

By introducing subtraction to primary 3 students in small, manageable steps, and with plenty of practice, your students should be able to master the concept of subtraction.
