An end-of-unit quiz on trigonometry (with some pythagoras and other geometry thrown in) for GCSE classes. I originally made this as a presentation on Google Docs. A link to the original and the .pdf version are both shared below. EDIT --------- Now added are worked solutions to all problems. Hope this is helpful. EDIT --------- Now *corrected* solutions - Thank you @lewisbennet101

Can issue sheets one-by-one to students to first categorise and then solve. Each triangle has one correct and one incorrect 'working&' card and one correct answer to the missing side.

A challenging puzzle using a combination of several angle rules. With space at the top to make notes/examples of the necessary rules. Students will need to recognise the conventions for labelling an isosceles triangle.

A set of problems based on Colin Foster’s excellent Mathematical Etude .

Cut out into dominoes. Learners can sort them into a loop by following instructions on the cards to practise finding mean, median, mode and range.

I wrote these for my year 11 class after coming across a particularly horrible question in an EdExcel GCSE Practice Paper. The problems require students to do (at least) two conversions. Some correct numbers for predicted strategies are given, but there are lots of possible approaches. Beware - these questions are hard!

A simple idea. Calculations with time given different pieces of initial information. The extension comes from Robery Kaplinsky’s wonderful Open Middle website: http://www.openmiddle.com/operations-with-time/ Answers included.

Students use colours to help them recognise and identify the different angle rules.

A set of spider style worksheets for dinging fractions of amounts (and going backwards) with answers included. Original file in Google Slides.

Three images to pop into a IWB presentation. I suggest using like this: Use large IWB version to demonstrate examples, eg. add numbers to the scales and ask students to help find missing value, perhaps on mini-whiteboards. (See questions for examples of how to vary the questions). Then get students to practice using the six similar questions; answers provided. Could require students to set up equations using notation before solving, or just to find the missing value using affine reasoning.
