1. Changing the Subject of a Formula – With Factorisation – Link
Students need to match the questions on the left to
the answers on the right.
Students should place corresponding letters in the boxes on the right.
The worksheet is provided in a variety of sizes/formats.

2. Printing To print handouts from slides -
Select the slide from the left. Then click:
