Multiply the digits, then place the zeros
9 × 80 is 9 × 8 tens: 72 tens, or 720. Common Core 3.NBT.3 asks third graders for these, one digit times a multiple of 10 from 10 to 90. Break the tens apart: 7 × 20 = (7 × 2) × 10 writes the step out. The same move gives 6 × 700 = 4,200 and 30 × 40 = 1,200.
Watch the fact that ends in zero
50 × 40 = 2,000 has three zeros, because 5 × 4 = 20 brings one of its own. Pupils who count zeros without multiplying write 200. An extra zero: 50 × 40 = 2,000 holds only such problems.
- Which number times 40 makes 280? is a first look at dividing by tens: 280 ÷ 40 = 7.
- A multiples of 10 multiplication worksheet is quick to mark aloud: read out the answers while pupils mark their own.
