An hour can be cut into two halves or four quarters, just like a pizza. This 3rd grade fractions of an hour worksheet has four items, numbered 1 to 4, on grid paper. A blue circle at the top gives the chart: 15 minutes is a quarter hour, 30 minutes is a half hour and 60 minutes is 1 hour. In item 1, your child changes 60 minutes into hours. Item 2 asks which part of an hour makes 2 quarters, and item 3 turns 4 half hours into hours. Item 4 changes 5 quarter hours into hours and minutes, while a yellow school bus waits at the bottom. Page two works out each step in pink.
