A full lesson on substitution. Depending on the class you may want to use all of it or just a couple of slides. It starts by looking at the very basics (front bit is quite slow you may want to chop it down a bit), before having some differentiated questions for the pupils to work through before moving to a catchphrase puzzle. :-)

This is a lesson I made on sample spaces. It is quite class specific so you may need to do a lot of adapting to the middle section to make it fit to your class. Nice question at the end though where I got pupils to work in pairs to justify their answers.

Here is a complete lesson on Pythagoras' theorem with included assessment opportunities and printable differentiated worksheets on the IWB. Extension tasks using Pythagoras to find perimeters and areas of shapes too. There is a quality activity which I printed out where pupils have to role 2 dice to select the base and height of a right angled triangle then use the information to calculate the hypotenuse. I have included teacher hints on the slides which need deleting out because there are a lot of things that need clicking or pulling out. Enjoy!

Break the class in half and each team take it in term to answer questions and gather points by answering a question square then clicking on it. Covers proportion including the unitary method.

Quick catchphrase of simplifying some basic algebraic expression.

Here a lesson designed for lower attaining key stage 3 student as an introduction to simplifying algebraic activities. Contains a range of different activities.

An interesting lesson based around pupils trying to estimate lengths. Nice starter based on estimating some strange lengths with multiple choice answers. At the end there is a task where pupils have to work in small groups to create strips of certain lengths.

KS3 activtiy where pupils are required to collect like term to match up expressions then an extension where pupils are required to expand a single bracket and match it up a expression.

An activity for pupils to play in pairs based on blooms. Just as in normal noughts and crosses pupils need to make a line of 3, but instead of nought and crosses they must write their answer in a noughts and crosses grid. As an extension for those who finish I get them to work as a pair to complete the rest of the grid.

Think of a number (algebraic proof)This is a collection of resources I made for a lesson to introduce the idea of algebraic proof to a year 7 class. I gave prep sheet for homework, then we completed proof as class. Using 'blob and dot algebra' then real algebra. Pupils then made their own puzzles and a poster. They really enjoyed it!

Here is a lesson on similar triangles where pupils need to calculate scale factors. It starts with pupils using it to calculate the height of a building and looking at some examples. Before pupils trying some differentiated questions then applying the skills to 2D and 3D objects. I have included teacher hints on the IWB showing where to click things please delete these out.

A full lesson with learning plan and IWB (smart notebook) on area and perimeter of traingles. Contains differentiated questions and printable progress and plenary cards and a nice sorting activity depending on whether they are given its area or perimeter.

Each set of problems contains 3 maths problems which I have pulled together from a number of books and websites. Problem 1 is easy, problem 2 is medium and problem 3 is hard. We printed them big on A3 coloured green, orange and red to make a display with pupils submitting their solutions. puzzles, problem solving,
