Maths - Free Resource Library

(188)
This is a library of Maths teaching resources I have put together over many years. The word document is just a few things to bear in mind when using it. It was originally on Dropbox, but that seemed to be a little unreliable for some people which is why is has been moved across to google drive, with the link below. If this library helps you then please leave some positive feedback! :) The library can be found here: https://www.mathsfreeresourcelibrary.com/
3D Trigonometry

3D Trigonometry

(46)
Powerpoint to be used to explain how to use Trigonometry in 3D shapes. Includes a starter, main explanation and a plenary. If you like this resource then please check out my other stuff on here! :)
Exponential Equations

Exponential Equations

(9)
Pupils learn to solve equations where the unknown is in the 'power', by changing the base so the powers can be compared (ie - logarithms not needed). The powerpoint has been made to go with the Cambridge IGCSE course but could easily be adapted. If you like this resource then please check out my other stuff on here! :)

17 Equations that Changed the World

(104)
Having read Ian Stewart's book of the same name, I decided to make A4 sized posters summarising each of the equations. They're nice to have up on the walls when kids say 'What's the point of Algebra?' If you like this resource then please check out my other stuff on here!
Areas of Flags (with circles)

Areas of Flags (with circles)

(26)
A while ago I uploaded a set of resources on calculating the areas of shapes on flags, see here: https://www.tes.com/teaching-resource/areas-of-flags-6327719 A number of people messaged me asking if I had one for circles - and here is is now! I had to get creative with finding flags I could use, and I’d recommend that you have already had a lesson on Area and Circumference before this, as the questions get very challenging! Thank you to @1hannahjones for making a number of corrections and clarifications!

Algebraic Fractions
Owen134866Owen134866

Algebraic Fractions

(1)
This resource has been made to go with the IGCSE course but should be fine for others. Pupils see how to add Algebraic fractions, as well as deal with some equations with fractions in. There are quite a few topics which need covering before this lesson! If you like this resource then please check out my other stuff on TES! :)
Iteration and Square Roots
Owen134866Owen134866

Iteration and Square Roots

(3)
In this lesson, students learn what iteration is and see an example of how it was used to calculate square roots of non-square numbers. There is an explanation of the notation involved and students get to try the process out for themselves. Could be used as an introduction to the topic.

Flags Game: KS3 / KS4 maths number activity
Owen134866Owen134866

Flags Game: KS3 / KS4 maths number activity

(0)
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!
Volume of Pyramids and Cones
Owen134866Owen134866

Volume of Pyramids and Cones

(33)
Pupils learn to calculate the volume of pyramids and cones using the relevant formula. There is a selection of harder questions to challenge the more able on the sheet. In the powerpoint is a link to a demonstration of the formula (not involving calculus as students studying this topic most likely will not have encountered this yet!). The video is NOT my own work - credit goes to mathematicsonline for that! If you liked this resource then please check out my other stuff on here!
Plotting Straight Line Graphs
Owen134866Owen134866

Plotting Straight Line Graphs

(93)
In this lesson, student learn how to plot straight line graphs by using a table of values. There is a sheet of questions that they can get straight into without having to draw out axes. In addition, there is a good question about investigating what happens if you switch the x and y values in an equation, which should lead to some nice discussions and discoveries!

Which games are worth it?

(1)
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!
Standard Unit Prefixes (Standard Form extension)
Owen134866Owen134866

Standard Unit Prefixes (Standard Form extension)

(8)
Pupils practice Standard Form (which they should be familiar with before this lesson is taught), and learn about many of the prefixes used. For example changing milligrams to micrograms, how big is a yottametre compared to a picometre etc. Why say 1000 kilometres when you could just say 1 Megametre? They usually find all the names of units quite interesting! If you like this resource then please have a look at my other stuff on here! :)
Stretches and Shears
Owen134866Owen134866

Stretches and Shears

(4)
Powerpoints that show pupils how to transform shapes by stretching and shearing. This was made to go with the Cambridge IGCSE course and textbook, which has plenty of questions for them to practice. If you like this resource then please check out my other stuff on here! :)
Who wins the Heptathlon?
Owen134866Owen134866

Who wins the Heptathlon?

(7)
Lesson on the official formulae used to calculate the amount of points athletes get for different events of the Heptathlon. An important part is the discussion afterwards as to whether the scoring system is fair or not (an article is linked in the powerpoint) If you like this resource then please check out my other stuff on here!
Euro 2016 Simulation (Probability)
Owen134866Owen134866

Euro 2016 Simulation (Probability)

(5)
This sequence of 4 lessons is based around students using probability to simulate the upcoming Euro 2016 tournament using dice. I have included an 'instructions' document explaining as well as I can how each lesson should go, but it is advisable to go through this as a faculty first and play it yourselves! If you have any questions or corrections that I need to make then please contact me. Please note that the lessons are heavily based on the work of TES uploader 'dannytheref', who created a similar set of resources for the World Cup 2014 (https://www.tes.com/teaching-resource/fifa-world-cup-2014-simulation-activity-6424677). There is also a similar activity on nRich (https://nrich.maths.org/1184). I also need to credit www.excely.com for the creation of the superb spreadsheet used within.

Maths of the Fretboard
Owen134866Owen134866

Maths of the Fretboard

(2)
Students see how geometric sequences can be used to calculate distances on a guitar fretboard. There are several questions to discuss, and a lot of nice uses of formulae. Should also give them a nice practical example that isn't of the type often found in textbooks! If you like this resource then please check out my other stuff on TES (all free of course!)
Even more Maths Relays!
Owen134866Owen134866

Even more Maths Relays!

(9)
Another set of 5 relays, this time aimed at Y9 students. Also included is an example of how I use them and a scoring sheet. Most of the questions have been pilfered from nRich or the UKMT, so are not my own work... If you like this resource then please check out my other stuff on here! https://www.tes.com/teaching-resources/shop/Owen134866 The relays are originally based on Chris Smith's set, uploaded here: https://www.tes.com/teaching-resource/maths-relay-races-problem-solving-puzzles-6064073 And my other set of 5 is here: https://www.tes.com/teaching-resource/more-maths-relays-11026512
Make 50!
Owen134866Owen134866

Make 50!

(4)
Pupils have to make the numbers from 1-50 using 1, 2, 3, and 4 once each only. They can use any operations as well as indices and factorials. Includes a sheet of possible answers! If you like this resource then please check out my other stuff on here!
Diophantus' Triples
Owen134866Owen134866

Diophantus' Triples

(3)
A lesson on the rules Diophantus came up with to create Pythagorean Triples. The main challenge is for higher ability pupils to prove why his method works using algebra. Weaker higher level pupils should still be able to do the numerical version though, and possibly start on the algebraic one... If you like this resource then please check out my other stuff on here!
Algebraic Number Pyramids
Owen134866Owen134866

Algebraic Number Pyramids

(2)
Pupils investigate how to make a number pyramid have the largest number at the top, given some numbers they have to put at the bottom. They should then try to explain (algebraically if possible) why it works. Leads into Pascal's Triangle and I usually give them another lesson investigating whatever patterns they can find within it! The 1st page is for the lesson and the 2nd page with the triangle on it is for the investigation. If you like this then please check out my other stuff on here! :)
