Lesson on using Probability to decide whether games are worth playing, based on the cost of playing and the potential winnings. If you like this resource then please check out my other stuff on here!

Pupils plot graphs of the world records in some events over the last century. They try to explain differences in their graphs and why they take the shape they do. If you like this resource then please check out my other stuff on here!

Before doing this lesson, pupils should have seen perpendicular bisectors, angle bisectors, and constructing a perpendicular from a point to a line. The idea in this lesson is that pupils get asked, 'Where is the centre of a triangle?', and have to come up with ways to define what this means, and see if they can use a compass, ruler and pencil to find it. I tend to just pose the question and let them go to town on it! I have included some possibilities and how to construct them, but its more down to them to decide for themselves. There are also hyperlinks in blue where you can show them in more detail, and there are often some puzzled expressions when it seems possible that the centre isn't even in the triangle. Can even bring in centre of mass too! :) If you liked this resource, please check out my other stuff on TES! https://www.tes.com/teaching-resources/search/?f=authorId%5B2095097%5D

Pupils should work in pairs or threes, drawing right-angled triangles of various sizes in their books. They then work out the height to base ratio and the angle that goes with them (effectively creating a 'Tan' table). There is then some discussion of how to use this to answer questions. You will have to write on the powerpoint at some point! You could probably then create a follow up lesson which is a bit more practical...

I think I originally saw this idea on the TES website, but I can't remember where! Pupils investigate what amounts of money can be made with one of each coin up to a 50p piece. They can then investigate what extra coins they would need to make all the amounts up to 99p. There is also an extra extension where they can try to find a more effective coinage system for this!

Based on a 10 Ticks sheet, the pupils make a magic square by substituting numbers into very simple expressions. Also explains Algebraically why it works! This could be extended into 4x4 squares for higher ability groups. If you like this resource then please check out my other stuff on here!

This game is good for end of term lessons. You split the class into teams (3-4 works best). You roll 3 dice for each team and they have to use the numbers however they want (including as indices or factorials) to make numbers from 1-64. Points are awarded as explained in the powerpoint. It works best if you roll the dice for all teams to start with and roll after their go, that way they can think about what number to make while you go round the other teams. It might take a bit of practice to get then hang of this but pretty much every class I've played it with loves it!

Pupils use angles and a bit of proportional reasoning to work out where some of the planets will be at a given time. They draw lines between them and if done accurately will end up with some lovely pursuit curves. Includes a plenary involving pi in case they have covered it as well! The starter is in the worksheet so you can give them a paper copy to do it on. If you like this resource then please check out my other stuff on here! :)
