Number Bonds
Many children, especially those with dyscalculia, find it hard to memorize number facts but can understand a number as parts that fit together. This tool shows a whole split into two parts, so a child sees how numbers decompose and combine, and you can print it for practice away from the screen.
See how a number splits into two parts. Move the slider to try every split.
Tap a pair below to set the split.
Each bond shows the whole and one part. Your child fills in the missing part.
What Number Bonds does
For a child who finds memorizing math facts stressful, the most helpful thing is often simply seeing how a number is built. A number bond shows a whole and its two parts at once: 8 is 5 and 3, and just as clearly, 5 and 3 make 8. The same picture explains both addition and subtraction, so they stop feeling like two separate lists to learn.
Number Bonds lets you choose a whole, split it into parts, and explore every way a number comes apart, on screen or on a clean printable page for practice. It is a gentle way to turn abstract facts into something a child can see, a common support for children with dyscalculia. From kindlexy.com.
