About this worksheet
Groups of base-ten rods to count as tens and write as multiplication.
What kids practice
Third graders multiply a one-digit number by a multiple of 10, like 4 × 60. The key idea is that 60 is 6 tens, so 4 × 60 is 4 groups of 6 tens, which is 24 tens, or 240. Children use a fact they know (4 × 6 = 24) and then think in tens.
Watch for
- Forgetting to make the answer tens. Writing 4 × 60 = 24.
- Dropping a zero when the fact already ends in 0. 5 × 80 is 400, not 40.
- Multiplying the tens digit and the zero separately and getting mixed up. Think of 60 as 6 tens.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full multiplying by 10s guide for 3rd grade.
