Number bonds are a foundational concept for mental arithmetic. They show how numbers can be split into parts:
- Easy: Bonds to 10 — the building blocks (e.g., 7 + ? = 10)
- Medium: Bonds to 20 — bridging through 10
- Hard: Bonds to 50 — more challenging splits
- Visual circle layout helps children see the part-whole relationship
- Multiple choice reduces frustration for younger learners
