Ten Times and One Tenth
See a digit worth 10 times the place to its right and 1/10 of the place to its left.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 44
- Welcome to the Measure Mill! The mill's scales run on place value. Move one place left, and a digit is worth 10 times as much.
- Move one place right, and it's worth 1 tenth as much. This works on both sides of the point.
- A digital scale shows it. If one playing card reads 1.3 grams, you'd expect 10 cards to read 13 grams.
- If 10 pennies read 24 grams, you'd expect one penny to read 2.4 grams.
Georgia's K-12 Mathematics Standards:
- 5.NR.1.1 β Explain that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left.
