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 I originally made this as a presentation on Google Docs.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.

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

<p>A set of problems based on Colin Foster’s excellent <a href="http://www.foster77.co.uk/Foster,%20Teach%20Secondary,%20Angle%20Chasing.pdf" target="_blank" rel="nofollow">Mathematical Etude </a>.</p>

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.

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

<p>A simple idea.<br /> Calculations with time given different pieces of initial information.<br /> The extension comes from Robery Kaplinsky’s wonderful Open Middle website: <a href="http://www.openmiddle.com/operations-with-time/" target="_blank" rel="nofollow">http://www.openmiddle.com/operations-with-time/</a><br /> Answers included.</p>

<p>Students use colours to help them recognise and identify the different angle rules.</p>

<p>A set of spider style worksheets for dinging fractions of amounts (and going backwards) with answers included.</p> <p>Original file in <a href="https://docs.google.com/presentation/d/1tld9NjVyhIsSbEwggXVhlF07R2Zk3kvGDTjKmM6v9e4/copy" target="_blank" rel="nofollow">Google Slides</a>.</p>

<p>Three images to pop into a IWB presentation.<br /> I suggest using like this:<br /> 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.<br /> Could require students to set up equations using notation before solving, or just to find the missing value using affine reasoning.</p>
