I hate having waste, so calculate how many people I should invite to the party to ensure that I have no left overs.

I did this for an interview and it seemed to go quite well. It is plotting the reciprocal functions by considering the values of the original functions.

Help Santa and the elves by writing and solving, when required, some inequalities regarding Santa's trip on Christmas Eve.

Calculate how much each of these people need in each case. It is essentially rounding to the nearest 10, 100 and 1000.

I found a graph on the BBC News website showing the breakdown of the cost of fuel in Britain and thought that the students could calculate the percentage of each cost from the price of one litre.

Cartoon Linear Graphs: Get from one character to their sidekick and tell name the line upon which they've just travelled in the graph. An attempt to make linear graphs a bit more interesting.

A set of worksheets where students work out the equations of the lines travelled by the fireworks.

Find the words and use them to complete sentences. Designed for lower ability in secondary school who will then have some notes too!

I wrote this for students who aren't that keen on algebra, so have interspersed some relatively easy numerical problems with similar algebraic problems, getting them to write down their thought process to solve them. The ultimate aim is to show the students that the equations are just like the numerical problems.

Same as all the others - answer the questions and unjumble the letters to find your next destination.

Three sheets varying from basic up to difficult. Angles 1 - lines, around a point, triangles. Angles 2 - parallel lines, polygons. Angles 3 - circle theorems. Each QR code links to a song where the band or song contains either a number or colour and they must find the final code. Could lead onto questioning and explanations as to how they arrived at their answer.

Putting surface area into some kind of context without using wrapping paper (next best thing here mind). Two worded questions and one which involves two different units of measurement.

One fish pun on percentage multipliers and one on calculations (including percentage change). Useful for online learning or a classroom activity.

Here’s another one; answer the questions and reveal a rather nice fish-related pun. This involves circumference and area of circles, including fractions of circles at the end. Ideal for classroom, online or homework activities.

I got this idea from DaveGale (thanks by the way!) and the QR Code links to a video of Homer Simpson on YouTube. I used the website qrstuff.com to generate the original code then deleted some bits so that the kids needed to answer the questions correctly etc. It gives them a real reason to have their phone out too!

Choose the numbers that are either multiples or factors of the number in italics and unjumble the letters to find a football team.

Six students run a race and their races are described; draw the graphs then work out in which order they came.

This is part of a genuine news article from the BBC News website. Students are required to calculate the percentage changes in the article.

Scrat is the sabre-toothed squirrel in the Ice Age films. Watch the video and answer the questions on areas of circles and units of measurement. This is designed as either a starter or plenary. Video (http://www.youtube.com/watch?v=etKCHLgW_o0) now on the powerpoint.

No real imagination here, just a quick worksheet to stop the students bisecting a horizontal or vertical and bisecting a right angle. Don't expect anything fancy people...
