What you’ll learn

  1. Counting in 4sSkip count by 4s from 0 up to at least 48.Counting by 4s makes hops of four: 4, 8, 12, 16, 20, 24. The numbers climb quickly and form the start of the four times table. Practicing the pattern makes multiplication feel easy later.
  2. Counting in 8sSkip count by 8s from 0 to at least 96 and connect 8s to doubled 4s.Counting by 8s makes big hops: 8, 16, 24, 32. A neat trick is that every 8s number is the matching 4s number doubled — 12 doubled is 24, 16 doubled is 32. That link makes the eight times table much easier.
  3. Big Steps: 50s and 100sSkip count by 50s and 100s, reaching large totals quickly.Counting by 50s lands on numbers ending in 50 or 00, and two fifties make each hundred. Counting by 100s takes the biggest hops of all, always ending in 00. These giant steps reach big totals fast.

Questions this course answers
