Tell multiplying comparisons from adding ones.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 23
- There are two ways to compare. Ava has 5 shells. If Leo has 3 more than Ava, add: 5 plus 3 is 8.
- If Leo has 3 times as many as Ava, multiply: 3 times 5 is 15.
- Read carefully! "More than" adds on. "Times as many" makes copies. Leo has 15, so Leo has 10 more than Ava, and 3 times as many.
