Addition and Subtraction with Model/tape diagrams teaches students to determine unknown whole number in addition and subtraction equations by interpreting and understanding “WHY” and “HOW” to solve such equations.

Using the model method, young learners are able to visualize the concept. It sets a strong foundation for young learners before they progress to problem solving.

This pack of resources help students to understand:
- Why subtraction is applied when solving an unknown addend problem. (For example 7+ ___=10)
- How to determine unknown whole number on the left side of an addition or subtraction equation. (For example __+ 8 = 10, 5 + __ = 11, __ - 8 = 10 and 14 - __ = 5)
- How to interpret “more than” or “less than” problems without relying on “cue word”.
