Use Pie Charts to Compare Fractions
Help your child compare fractions visually by teaching him to draw pie charts. If he's comparing 2/3 and 4/8, draw two equally-sized circles next to each other. Divide the first into 3 slices and shade 2 of them. Divide the second circle into 8 slices and shade 4 of them. Ask your child to compare the drawings and tell you which pie chart has more area filled in.
