This is designed to get students thinking rather than just blindly following a mathematical recipe. There a four sets of 4 problems which all have the same answer (given in the centre of the screen). Each question has a blank for the students to fill in and sometimes there is more than one answer for the blank. This particular one covers probability, percentages, fractions, ratio, angles, equations, gradient, indices and other topics. I will be using these as starters to get students thinking.

This takes students through everything they will need to know about sets and Venn diagrams, building up to the hardest type of question (hence the name).

This details the skills required to perform GCSE proofs up to grade 8/9 building up from the basics to the more complicated questions.

Work your way up to 3D Pythagoras and trigonometry…

Deputy Nick Crimes needs to navigate at night using bearings and exact distances between locations to avoid zombies. Can you find the bearings and distances he requires?

This resource consists of a PowerPoint and worksheet with answers.\nThe aim is to divide the villains up in the given ratios for Batman and Robin to tackle, then find the ratio by simplifying.\n\nIdeal for KS3 and KS4 students.

Answer the differentiation questions, find the letters and reveal the punchline to a (terrible) joke. My class in Year 12 actually request these only to groan enormously when the answer is revealed. Just meant for a bit of practice, a starter or a plenary. Version 2 contains second derivatives.

Calculate the answers to the problems to solve the riddle!

Find the percentages of a number to reveal a Tim Vine joke. Error corrected.

Dr Doom has designed a virus that has infiltrated superhero gadgets and suits. Find the probability of each hero's gadget working. This involves simple probability, expected outcomes, relative frequency and a challenge of mutually exclusive events. It can be done as a discussion activity or as a worksheet where the challenge is on the back.

This was an idea I had in on the way to work one morning - Clive makes mistakes on his homework and you need to correct them, explaining the mistake he's made in each case. I intend to use this as a plenary or starter to check learning etc. They should create discussion too. There are 5 different mistakes to correct.

Practice on the function notation (new to GCSE!) involving substituting into a function and finding the value of x given what f(x) equals. This also involves composite functions. This should hopefully encourage your class to talk about their answers and understanding of the topic. Now includes an extra "find the inverse" slide!

Erica is struggling a little again and needs your help to correct what she's done and then tell her what she has done wrong. This allows students to discuss what they would do and check through solutions carefully.

Erica's struggling again - please help her sort out her misunderstandings. This is, like all the others, design to create discussion and tap in to the new curriculum and question style.

Erica has recently had a homework on exponentials and logarithms (including natural logarithms) and is really srtuggling. Can you help her by correcting her answers and explaining her mistakes? Designed to encourage discussion and the ability to check work carefully, as the new A level course seems to like.

Four sets of four problems where students have the answer but there are blanks in the questions which require filling in. This is designed to create discussion in class and hopefully provides natural differentiation (stretch the “top end” by finding the general solution where possible compared to finding a single solution). I will be using these as starters or plenaries as I believe they will develop deeper understanding of topics, but feel free to use them as you like (you will as you don’t need me to hold your hand).

Using the 'Chart of the Day' page (linked) I have set some questions on real life data. I'm sure you could all come up with better questions, but hopefully this will give you a start.

This is higher GCSE or A Level co-ordinate geometry which involves rearranging equations to the form ax+by+c=0, finding an equation given a point etc. The joke made my class groan massively, but I was in stitches mainly due to their reaction!

There are 6 spiders here: two on speed, two on density, one on population density and one on pressure. This is designed to create discussion as well as offering students the opportunity to practise new skills.

Clive's made mistakes on his homework again. This time it is on expanding two brackets and factorising quadratics. Students need to find Clive's error in each question and involve common mistakes I've seen made in class and in tests/exams. These are designed to assess understanding and to generate discussion.
