What children learn in Level 70
- Decimals can be more than one. 1 and 25 hundredths is one whole grid and 25 hundredths of another.
- The whole number goes before the point, and the hundredths go after it.
- Money works the same way! A cent is one hundredth of a dollar. 62 cents is 62 hundredths of a dollar: $0.62.
- A store owes you 62 cents, so it writes a refund check for $0.62: 0 dollars and 62 hundredths.
Georgia's K-12 Mathematics Standards:
- 4.NR.5.2 β Represent, read, and write fractions with denominators of 10 or 100 using decimal notation, and decimal numbers to the hundredths place as fractions, using concrete materials and drawings.
