Learning Can Be Fun - Magic Triangles - Addition & Subtraction

So simple in design... so easy to use...they must be magic! The simple format allows young children to work without adult supervision while they learn, memorise, and self-check the addition and subtraction facts for numbers 1-10.

Use a whiteboard marker to complete the revision exercise on the back of each laminated card.

Contains 35 cards measuring 13.5cm x 13.5cm.

Addition

The sum of the two bottom numbers equals the number at the top of the triangle. 7 + 3 = 10 3 + 7 =10

Subtraction

Start with the number at the top. Choose a number at the bottom to subtract. Cover the selected number. The answer will be the remaining bottom number. 10 - 7 = 3 10 - 3 = 7

Q: What are "Magic Triangles" and how do they help with addition?

A: Magic Triangles are a clever visual tool designed to show the relationship between three numbers in a "fact family." For addition, the sum of the two numbers at the bottom corners always equals the number at the top peak. Children can cover one number to practice finding the missing part of the equation.

Q: How does this set teach subtraction?

A: Subtraction is taught as the inverse of addition. A child starts with the number at the top of the triangle and subtracts one of the bottom numbers. By covering the chosen bottom number, the remaining bottom number is revealed as the correct answer (e.g., if the top is 10 and a bottom corner is 7, the other corner must be 3).

Q: What is included in the Magic Triangles Addition & Subtraction set?

A: The set includes 35 sturdy, laminated double-sided cards measuring 13.5cm x 13.5cm. These cards cover addition and subtraction facts for numbers 1 through 10. The back of each card features a revision exercise that can be completed with a whiteboard marker.

Q: Are these cards suitable for independent learning?

A: Yes! The simple, color-coded design allows young children to work without adult supervision. They can "self-check" their answers by simply lifting their hand to reveal the hidden number, which builds confidence and reinforces memorization.

Q: What age group is this math resource designed for?

A: This set is perfect for children in early primary school (approx. ages 5 to 8) who are beginning to explore basic arithmetic and number bonds.

Q: Can I reuse the cards for practice?

A: Absolutely. The cards are laminated and wipe-clean, meaning children can use a whiteboard marker to complete the activities on the back and then wipe them clean for endless practice.
