A simple plenary to draw out a misconception and to reinforce multiplication of independent events.

A powerpoint (with an initial starter involving indices) that covers why we use surds, simplifying surds, multiplying and rationalising. I have been using this with Year 11 intervention groups. There are also some example exam style questions and problem solving tasks. You may need some additional work to turn this into even a two or three lesson block.

A complete lesson on direct proportion including a starter and some GCSE style questions.

A complete lesson on solving equations, with a literacy element in the worksheet. The starter gets students to form expressions of equal value which is the basis of how you can demonstrate solving, and then some useful ways to explain using bags of sweets and loose sweets!

An initial lesson on Straight Line Graphs - lots of discussion and drawing of lines so students should make the link between gradient / intercept

Suitable for KS4 or able KS3 student this is an introduction to probability, with a discussionon the probability scale, through the basics of Tree usage, right upto using a tree for "without replacement" questions. There are opportunities for discussion and extension within the worksheet materials

An investigative lesson where students can "discover" Pythagoras' theorem. Note - you will need to give each group of students a large number of accurately cut squares eg 6 x 6, 9 x 9 which I have not supplied.
