Multiplying by 10s Chart
4 × 6 = 24, so 4 × 60 = 24 tens = 240, shown with base-ten rods and more examples.
Count the Tens Rods

Fact Then 10s
Pairs like 3 × 7 = 21, so 3 × 70 = 210.

What it is
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.
What comes next
Multiplication properties and patterns, and later multiplying bigger numbers in 4th grade.
How to teach it
- Use bundles of 10, like ten-sticks of blocks or bundled straws.
- Say it in tens. "4 times 6 tens is 24 tens."
- Always find the fact first, then make it tens.
- Check that the answer is about the right size. 4 × 60 should be more than 200.
Common mistakes
- 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.
