Age

5.

Preparation

This is an individual presentation.

Presentation

1. Have the child bring over the two trays of fractions.

3. Read the equation. Ask the child if he knows by how many will we be dividing.
4. Have the child place two skittles in a row below the trays.
5. Ask the child how many 4ths we need to start. (four 1/4)
6. Place all of the 4ths below the tray.
7. Tell the child that we need to share these 4ths evenly between our two skittles.
8. Have the child give each 1/4 and then another 1/4.
