Number Bonds
What makes 10? 20? 100? Quick bonds for young learners.
About Number Bonds
Number bonds practice for children: find the missing number to make 10, then 20, 50, 100 and 1000 as you progress. Speed-run mode turns it into a race, which young learners love.
How to play Number Bonds
- Find the number that completes the bond.
- Choose a mode: Classic (10 timed questions), Speed run (60 seconds), Survival (three lives) or Daily (the same questions for everyone today).
- Tap an answer or press 1–4. Faster correct answers score more, and three in a row adds a streak bonus.
