Fraction Booster Hot

From site: There are five levels to work through. In level 1 you simply type in the number of children to share the pizza and the pizza will be cut into fractions for you. At Level 2 you drag fractions to complete a fraction wall. In Level 3 you have to count the number of shaded squares and the total number of squares then type in the fraction (use a slash e.g. 1/4). Level 4 introduces a fraction numberline for you to drag the fractions onto. Level 5 uses a pizza to illustrate fraction equivalences.
