About Multiplying by Multiples of 10
What this skill is
Multiplying by multiples of 10 (like 40 x 30 or 6 x 500) teaches students to multiply basic single-digit facts first, then attach the total count of trailing zeros to the product.
When children learn it
Multiplying by multiples of 10 is taught in 3rd through 5th grade, aligned to 3.NBT.A.3 and 4.NBT.B.5.
Teaching Tips
- Solve the basic fact first (5 x 6 = 30), then attach all zeros from both factors (two zeros -> 3,000).
- Count zeros in both factors combined.
Common Mistakes
- Missing a trailing zero when the basic fact product ends in zero (for 50 x 60, basic fact 5 x 6 = 30, so product is 3,000, not 300).
- Adding wrong count of trailing zeros.
