Explore ways of representing decimals using mathematical notation and visual tools. Match a decimal fraction between 0 and 1 such as 0.7. Adjust units on a range of visual scales and other representations. Work with a random selection of two of these representations: common fraction, number line, counting frame, dial, array and pie chart. Match at least three decimals with each tool. This learning object is one in a series of nine objects.
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.
In this game from Count On you practise finding a fraction of a number. You can play it as a two-player game or a single player can play against the computer.
