What children learn in Level 62
- The bakery has 2 whole trays of muffins and 1 fourth of another tray. That's the mixed number 2 and 1 fourth: a whole number and a fraction.
- Count the fourths: each whole tray is 4 fourths. 4, 8, and 1 more makes 9 fourths.
- To go back, take out groups of 4 fourths. 9 fourths is 2 groups of 4, with 1 fourth left: 2 and 1 fourth.
- On a number line, 2 and 1 fourth is 1 fourth past 2.
