What you’ll learn

  1. Your Math ToolboxMeet math tools — counters, number line, and fingers — and what each does best.Math has many tools. Counters are best for touching and moving small groups. A number line is best for counting up or back in hops, like 5 + 3 landing on 8. Fingers are always handy for quick sums up to 10. Each tool shines at a different kind of job.
