#### Congruent Shapes KS2/KS3

Lesson for identifying congruent shapes and learning the meaning of congruence. Aimed at lower ability groups or KS2. Conditions for Congruence sheets used as memory tasks in groups of 4. 1 of the team comes up for each different sheet and has 30 seconds to remember the information and take it back to their team.

#### Shape terminology fill- in sheet

I think I originally devised this to accompany a PowerPoint presentation, though the presentation in question is the intellectual property of my workplace and not me. Anyway you might find it useful as an accompaniment to your lesson if you’re covering terms like congruent and similar. It’s designed to be kept handy for revision/ homework purposes.

#### 007 Problem-solving, geometry puzzle, G&T yr7

The problem of the dropped box of matches, pt 1 “Isabella Ringing dropped a box of matches, the box opened and the matches went everywhere. As she went to pick them up she knocked some of them into different positions. This gave her an idea for some puzzles to set for her friends.” A set of six matchstick puzzles to promote problem-solving skills - part 1 of 2. Suggested that it is used alongside ‘sticks’ of some sort so that kids can physcially explore the problem. We Solve Problems is a charity, founded by three PhD mathematicians, whose aim is to promote the use of advanced mathematics within secondary schools. We want to encourage creative mathematical thinking, to develop a skill within pupils for presenting their results clearly and coherently, as well as promoting personal problem-solving skills. Visit us at wesolveproblems. org. uk. We would very much appreciate it if you could take time to follow us, and hopefully review this resource as well, as this helps others to find us. Thank you.
