What children learn in Level 54
- Here is 2 thirds of a tray of muffins.
- Cut each third in half. Now there are 6 equal parts, and 4 are shaded. The shaded amount didn't change!
- Cut each part in half again: 12 parts, and 8 are shaded. 2 thirds, 4 sixths, and 8 twelfths are all equivalent.
- Cutting each part into 2 doubles the number of shaded parts and the number of parts in the whole.
Georgia's K-12 Mathematics Standards:
- 4.NR.4.1 — Using concrete materials, drawings, and number lines, demonstrate and explain the relationship between equivalent fractions, including fractions greater than one, and explain the identity property of multiplication as it relates to equivalent fractions.
