Nice ideas kickstart students investigations into the special values of pi, phi (golden ratio) and root2. Students will investigate the relationship between a circles diameter and its circumference and area, the numbers of the fibonacci sequence and real life and then the relationship between A3, A4, A5 paper.
Proving Trig Identities

Proving Trig Identities

(6)
Prove the trigonometric identities by matching up the peices, (steps) in the correct order. Supports students by providing the steps, and avoiding alebraic mistakes that confuse the key learning outcomes, whilst challenging them to understand the order and making connections between each step. Answers Included.
Solving Equations Game

Solving Equations Game

(0)
Pupils earn points by solving the equations. Easier questions earn less points so pupils self-differentiate and decide their own level of difficulty for themselves (although the teacher should check that they do this sensibly of course!). I tell pupils that those with most points after a given time period win. The competitive nature of this activity encourages pupils to push themselves more than they would usually and I’m always pleasantly surprised at what equations they can do here. Answers to the equations are included. as well as an easier version (v3) with no negative answers. Tried and tested in the classroom many times. This download includes a files as well as the original word files for easy editing.

This is a space-based KS2 / KS3 / GCSE matchup activity. Pupils consider and then rank relative altitudes of Earth features, satellites (natural & artificial) & stars. Pupils will match up and order the images, numbers and written information about each object. There are loads of maths aspects in here, deliberately included to make pupils think and question the points raised. A good real life ordering task or use as a prompt to introduce scale and scale models. Includes plenty of information to inspire as well as aspects to prompt questions and thinking skills. As well as maths and space science, can also be used as a literacy resource. Tried and tested in the classroom with various groups and ages (Yr5, Yr7, Yr8, Yr9, PGCE students). This download includes three versions of this activity - one specifically for primary pupils. Includes pdf files as well as the original powerpoint/word documents for easy editing.

Loads of files here… MathsTricks.ppt is a collection of some of the best, most engaging, maths questions and ideas that I’ve collected over several years of high school maths teaching. Use as lesson starters, discussion points, presentation/assembly materials or whatever other purpose you desire. Files here include… MathsTricks.ppt is a version to print, laminate and create a set of A5 playing cards where each card is one ‘trick’, like a magician! Includes both an editable Powerpoint file and a PDF. MathsTricksICT.ppt is a version of Maths Tricks to display on the whiteboard. This is same as above but with teacher’s notes removed. Includes both an editable Powerpoint file and a PDF. LinksAndNotes.doc is notes, answers and further links (YouTube videos etc.) for each trick. Includes both an editable Word file and a PDF. GreatQuestionsInMaths.docx is a small but great collection of interesting maths questions suitable for GCSE higher or A Level students. No answers here I’m afraid but some can be found in the links & notes document for the main Maths Tricks file. Includes both an editable Word file and a PDF. All of the Summer Fayre documents are a probability task extension of the original question Maths Tricks question. Files here include… SummerFayre.ppt is a single slide containing the original question TheSummerFayreAnswerAndNotes.doc explains the maths behind this game including the probability of winning / losing and the probability of the school winning / losing over multiple plays. TheSummerFayrePrompts.doc is a few starter questions that you could ask students to get them thinking about the maths behind this game. TheSummerFayreSimulation.xlsx is an Excel file demonstration of the probabilities behind playing this game many times.
Vectors Probing Questions

Vectors Probing Questions

(0)
This is an activity for Yr13 pupils to check and extend their understanding of vectors. This is a a set of questions to really check understanding of several vector concepts including magnitudes of vectors, vector equations of lines, scalar product and closest distance between a point and a line. Answers and workings included for our suggested vectors but you, the teacher, could choose to ask students for their own vector suggestions which would give completely different answers. Bonus Resource 1: Notes on Vectors. This is the set of ‘notes on a page’ that I give to my students doing this topic. Bonus Resource 2: Vector Triangles in 3D Space - A great problem-solving-style, simple question with many approaches and possible answers; Sort these triangles into scalene, isosceles and equilateral. Which are right angled too? The task involves using lots of those key vector techniques that students need to be able to perform. Sorry, no answers here this time though. Tried and tested in the classroom many times. This download includes all files as pdfs as well as the original word files for easy editing.
Graphs of Rational Functions
