Number bonds to 10
Every pair that makes ten, drawn as counters as well as numbers. This is the small set of facts that makes everything after it easier, so it is worth a page of its own.

What's on this chart
Ten is the hinge of our number system, and knowing its pairs by heart is what lets a child add 8+5 by making ten first and carrying the rest. There are only eleven bonds to learn, and this chart shows each one twice over: as a number sentence, and as a row of counters split into two colors.
Why this chart helps
The counters matter. A child who is still counting on their fingers can match the picture, count the two colors, and arrive at the fact honestly. As the pairs become familiar the picture stops being read and the numbers take over, which is exactly the handover a chart like this is for.
