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. With prompting students should be able to establish and generalise not only that when the three squares form a right angled triangle, then when they dont form a right angle what this means with regards to the opposite angle!

To use this lesson you will need a decent sized quantity of multi-link cubes or similar for the "Chocolate Factory" - the worksheet has two routes depending on how confident the students are at converting each type of fraction.

A notebook file for GCSE students detailing how to find the area / volume of similar shapes

Upto two lessons worth of work on simplifying expressions involving Indices. By the end of these lessons students should be able to simplify multiple terms.

A way of combining recognising types of number for lower ability students in KS4 or KS3 with the new Venn Diagrams element of the KS4 maths curriculum. You may also need some bingo books to use as a plenary activity for this lesson - see my Primes Bingo Resource.
