Codebreaker worksheet Here's a codebreaker worksheet I have used with my Year 7 class to get them to practise their addition and subtraction with decimals

I have created a Mathematics version of Pictionary. Encouraging mathematical language. To create the game cards I just printed off the slides (4 on a page) and then double sided them and laminated. They work great in class - especially for revision with Year 11s. For more info on the game see my blog post http://mrcollinsreflectivejournal.blogspot.com/2011/12/mathematical-pictionary.html I hope your classes enjoy.

A 39 page resource of the revision cards/activities I have used with my classes when finishing topics or when revising for exams. Included in the resource are templates for you/your students to create your own revision cards. There are over 10 different revision cards to create/use. I have also provided examples/pictures of cards I have made, and some they have created too! All instructions to create each card are included in the resource. Read more and see examples here -> http://goo.gl/zjtTxU

This is a plenary activity I do when teaching Properties of Quadrilaterals. I use my ABCD Fans (see my free resources) for this, but mini whiteboards would work just as well. 10 questions to test students knowledge on the properties of quadrilaterals.

A notebook (and converted PowerPoint) file on Expanding Brackets and Simplifying Expressions. This is a whole lesson's worth of content, possibly two lessons. Includes a starter to expand single brackets and collect together 'like terms' in simple expressions. Examples for you to go through with your class before giving students questions to attempt. There are then 4 different plenary activities to use with your class: a matching activity, a 'spot the mistake' activity, a 'noughts and crosses' activity and finally a 'Finish Him' question! I originally created this resource in SMART notebook but have converted it into a ppt for more to use/benefit from - I've added some animations to make it as usable.

This is the first of a series of 'stories' I have written for my students. This story involves some dinosaurs ('trinosaurs') in the shapes of common triangles. The 'trinosaurs' love to work out each others' perimeters and areas but have trouble working out their areas when they don't know their heights - cue 'The Pythagosaurus Rex' - who helps the other 'trinosaurs' work out their missing lengths (heights) using Pythagoras' Theorem. The story includes explaining how to find the perimeter and area of triangles (no trig involved), then explaining Pythagoras' theorem and some questions to attempt (answers at the back of the book). All pictures hand drawn by me! I show the story to my students at the start of teaching Pythagoras and get them to read it aloud in class - can be quite fun as it's a change from 'the norm'.

I used this question as a starter to consolidate learning of simultaneous equations with a top set year 10 class. Would work well as a plenary too? The question gets the students to form the simulatenous equations 1st based on a worded question using the characters from Finding Nemo!

Inspired by http://goo.gl/EUD8Mu I have created 20 Higher Tier h/w sheets for students aiming to get a C/B grade. The sheets alternate between non-calc and calc h/ws and will be used in Term 1 this year. I will then use some B/A grade h/w sheets (watch this space) in Term 2/3. These sheets are aimed at giving students revision of the topics needed to achieve C/B grades in their GCSEs.

A set of 3 calling cards I give to my students. They each get a set of three cards. I then put examples on the board and point to a specific length of a triangle. The class then hold up the card they think corresponds with the length.

I have recently created this presentation to run through with my Y11s in preparation for their GCSE Mathematics exams. The topics covered are: Stem & Leaf Diagrams, Scatter Graphs, Frequency Polygons, Questionnaires, Estimate of the mean from a grouped frequency table, Cumulative Frequency Curves, Box Plots, Stratified Random Sampling, Probability Tree Diagrams, Histograms and Two Way Tables. I've highlighted key points for each topic that students need to remember. A3 sheets with questions now uploaded for students to use as you go through presentation!

Based on a popular app, and having taken inspiration from the ideas of @reflectivemaths and @srcav, I have created my own Mathematics version to add a bit of literacy across the curriculum. This set includes the words: prime, odd, even, factor, cube, square and fibonacci. I hope these are of use as starters to introduce topics. Differentiated by hiding the letters to choose from initially and then revealing them if class struggle. For low ability I would reveal letters at the start.

Students work out the shortest path between A and G on the diagram. I used this with my year 8 class as a starter.

Based on a popular app, and having taken inspiration from the ideas of @reflectivemaths and @srcav, I have created my own Mathematics version to add a bit of literacy across the curriculum. This set includes the words: circle, segment, alternate, chord, intersect, angle and centre. I hope these are of use as starters to introduce topics. Differentiated by hiding letters to choose from initially and then revealing them if class struggle. For low ability I would reveal letters at the start.

This is a resource I have created for Pi Day 14/03/13. I have taken inspiration from the popluar app '4 pics 1 word&' and from the likes of @reflectivemaths, @srcav and @El_Timbre on Twitter. I use the resource with mini whiteboards to get students to write the word and the definition of it. Diff by hiding/revealing the letters to choose from. see http://mrcollinsmaths.blogspot.co.uk for more info.

Based on a popular app, and having taken inspiration from the ideas of @reflectivemaths and @srcav, I have created my own Mathematics version to add a bit of literacy across the curriculum. This set includes the words: cube, net, face, edge, vertex, construction and triangle. I hope these are of use as starters to introduce topics. I used them with mini whiteboards and got students to write the word and a definition for it. Differentiated by hiding letters to choose from initially and then revealing them if class struggled. For low ability I would reveal letters at the start.

This is another of my 4 pics 1 word resources that I have created having been inspired by @reflectivemaths and @srcav. The words in this presentation are radius, arc, sector, segment and chord. Good for literacy across the curriculum. I use these with mini whiteboards as a starter activity - students write down the word and their definitions. Diff by revealing/not revealing the letters for each set of 4 pics.

GCSE Foundation Revision. This is a topic audit that I am going to get my Year 11s that are sitting the Linear Foundation paper to complete at the start of their revision. All topics have been taken from the AQA Linear spec

Based on a popular app, and having taken inspiration from the ideas of @reflectivemaths and @srcav, I have created my own Mathematics version to add a bit of literacy across the curriculum. This set includes the words: letter, equation, formula, identity, and expression. I hope these are of use as starters to introduce topics. Differentiated by hiding letters to choose from initially and then revealing them if class struggle. For low ability I would reveal letters at the start.

I made these loyalty cards earlier in the year to be used with Y11 classes revising for their GCSEs. Can be easily adapted for any subject/year group where you can offer rewards for improvement, enthusiasm and performance in your lessons.

Based on a popular app, and having taken inspiration from the ideas of @reflectivemaths and @srcav, I have created my own Mathematics version to add a bit of literacy across the curriculum. This set includes the words: quadrilateral, hexagon, pentagon, octagon, interior, exterior, degrees, sum, regular and irregular. I hope these are of use as starters to introduce the topic of polygons and then look at the interior and exterior angles of regular/irregular polygons!?
