Frequently Asked Questions
What is a number bond?
A number bond shows how a number splits into two parts — for example, 10 breaks into 6 and 4. It's a core Singapore Math technique for building number sense before kids memorize addition facts.
What age or grade is this for?
Number bonds are typically introduced in kindergarten and first grade, usually starting with bonds to 5 or 10 before moving up to 20 and beyond.
Why leave a blank instead of just showing the answer?
The blank is the point — the child practices recalling or figuring out the missing part, which is what builds real number sense rather than just copying an answer.
