Flipping Fractions

Game

The students will need to be familiar with the different names for fractions before they play this memory game. They should read their cards aloud as they turn them up. They also need to make sure the other player has a chance to see the cards they have turned up in order to check what they have said.

Activity

The focus here is on dividing a region into fractions. The students use the copymaster to shade areas of the 12-piece slice to help them solve these problems. Alternatively, they could use 12 pieces of paper and arrange them the same way as in the illustration. The students could use a model of the slice to act out the problems.
The students’ answers to question 2 may vary from those given in the answers section. If the slice were shared equally among four people, then each person would get three out of 12 pieces of the slice or 3/12. Students working at this level will not be ready for an in-depth exploration of equivalent fractions, but it would be appropriate to show them, using the slices copymaster, that 3/12 and 1/4 are, in fact, the same.
You could use the fraction cards from the Fractions Memory game to talk about the answers to questions 1 and 2.
If the students need a visual model to help them solve question 3, they will need to decide how the 12-piece slice can be modified to make 24 pieces. The easiest way is to draw a line horizontally through each row (or vertically through each column).
