Does your child learn addition and subtraction as separate things?

Fact families show how addition and subtraction are siblings — related operations. Abacus makes the connection obvious.

Here’s the promise: You’ll learn how abacus teaches the inverse relationship between adding and subtracting.

🧩 Why Fact Families Matter

Learning fact families cuts memorisation work by 75%. Instead of 4 facts, learn one triangle of numbers. This builds deep understanding of inverse relationships.

🎯 How Abacus Teaches Fact Families

Bead set demonstration: Show 3 beads and 4 beads together = 7 total. Ask all four facts: “What’s 3+4? 4+3? 7-3? 7-4?” Missing number game: “5 + ? = 9. Which subtraction fact helps?” (9-5=4). Fact family triangles: Write numbers in corners, cover one, child finds missing relationship.

💡 A Parent’s Insight

“My daughter used to treat addition and subtraction separately. Abacus showed her they’re opposites. Now she uses addition to check subtraction automatically.”

You might wonder, “Does this work for multiplication and division?” Yes — same concept applies.
