Pick a letter that forms the shape described and find the punchline.

Working forwards, backwards, repeated percentage change etc using multipliers. It does what it says on the tin.

The title rather give the game away here; answer he questions, reveal the punchline to the joke. I like this joke!

Find the missing values, and the missing words in the comparisons regarding median and interquartile range.

Answer the questions, reveal the punchline to a joke. The graphs are both linear and non-linear.

Find which letter is positioned at the midpoint of the two coordinates given, unjumble the letters and reveal the punchline to a joke.

Fractions n different contexts including angles, formulae, equations, averages, sets/Venn diagrams and more. Three slides each with four questions of increasing difficulty…

Two sets of questions, one on calculating sides, one on calculating angles, where parts have been missed out. This encourages students to work forwards and backwards and not get into “algorithm mode” and hopefully helps deepen understanding (that’s the plan anyway).

The usual thing involving grouped frequency tables as well as frequency tables, working forwards and backwards.

Find where the images of the coordinates are following a transformation, reveal the joke and then (possibly) laugh.

Either sketch, figure out the equation, state intersections with axes or state maxima/minima of these trigonometric functions or a combination. There are 10 of increasing difficulty and hopefully discussions in class will be forthcoming…

I was asked to come up with some Olympic themed lessons so came up with four, each getting increasingly difficult. One was on drawing statistical graphs based upon medals tables, one on a race track (basically area and perimeter), one on speed and one on parabolas. Tuck in if you think they will be of any use.

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.

This covers reflections, rotations, translations and enlargements (negative and fractional scale factors) and combinations. Some they have to describe, some they have to draw.

These are terrible cheese jokes discovered by answering maths questions. There are 15 more if you like these. The students like the challenge of finding the punchline in my experience.

This involves the old water issue, requiring 4 litres when you only have containers of 3 litres and 5 litres, plus an interactive game from subtangent.com. I have done a powerpoint version exported from SmartBoard too, on request, and now I have worked out how to embed the video! Enjoy!

I now teach enlargements using the vector method and decided to produce a worksheet to encourage this method, which involves fractional and negative scale factors.

Answer the questions, reveal the punchline; this old chestnut once again! It includes ascending and descending sequences.

The usual thing: answer the questions, reveal the punchline. This gives inequalities and asks students to find the representation on the number lines. The letters are jumbled up to stop them guessing the answer.

The usual: “do the thing, reveal the punchline to cheesy joke”. Students seem to like them (and some of my classes rate the jokes in their books).
