### Savannah Dreams

A delightful picture book, with a simple story about Savannah and her family as they go hunting in the bush. Over Sunday to Friday, the rest of the family discover lots of delicious bush tucker and count how many crabs or snakes or waterlily stems they have caught or collected, but Savannah finds only junk. That is until Sunday, when Savannah makes the greatest catch of all.

Use questioning to explore ways to make grids, represent fractions and find equivalent fractions.

• What factors can we use to make a grid to show twelfths?
• What boxes should be coloured to show three quarters? How else could it be done? Discuss other ways of colouring the same fraction (i.e. colouring different boxes).
• How do we write the fraction for this display? Is there another way to write this fraction? Is there an equivalent fraction? How do you know?

Students working in pairs at computers can:

• set the grid controls to manual
• set the fractions control to either manual or auto
• find and record all the equivalent fractions possible for a grid with 10 boxes
• choose their own grids to find and record equivalent fractions for $$\frac{1}{4}$$.
