About Multiplying Decimals
What this skill is
Multiplying decimals multiplies numbers as whole numbers first, then places the decimal point in the product by counting total decimal places across both factors combined.
When children learn it
Multiplying decimals is taught in 5th grade, aligned to Common Core standard 5.NBT.B.7.
Teaching Tips
- Multiply as whole numbers first, ignore decimal points initially.
- Count total decimal places in both factors and count back from right in final product.
Common Mistakes
- Aligning decimal points vertically during multiplication setup (unnecessary and confusing).
- Miscounting total factor decimal places when placing decimal point in final product.
