Tarsia – 2D Shape Properties

  • How well do you know the properties of shapes?
  • What is it? - Those of you who have used my website over the last few years (and read last week’s Resource of the Week!) will know what a huge fan of the Tarsia Jigsaw software I am. It can be used to very quickly create jigsaw and card sort activities on a whole host of mathematical topics for any age and ability level. The jigsaws can then be solved by students working on groups, racing to get their pieces into the correct order, having fruitful discussions and consolidating their understanding along the way. And the topics covered are certainly not restricted to number and algebra. This particular jigsaw concerns the topic of identifying the properties of 2D shapes.
  • How could it be used? - The conventional way to approach Tarsia in lessons is to have students working in small groups, armed with a pair of scissors (if, like me, you get them to do the work of cutting out the jigsaw), and leave them to solve it. This is absolutely fine for a good consolidation exercise and as an alternative to working through textbook questions. However, for a real challenge, why not make a few little adjustments to the jigsaw. For example, leave some of the shape cards blank and get the students to come up with the name given the unpaired properties. This particular activity would also lend itself well to challenging the students to make accurate drawings of each of the shapes once the jigsaw has been completed. A final piece of good advice I once received of Gill Hillitt is to make sure you print of the Input screen (with the answers removed) so once the jigsaw is complete, students can fill this in and have a record of their work that they can take away with them.
