    Names and properties of triangles

    Lesson presentations and activities

    • Angles and Polygons, 2D Shapes
      Key Stage: 3 ★★

      Can you arrange eight of the property cards around the outside of this grid and then draw quadrilaterals in the grid which have the properties corresponding to both their row and column?

      This game provides an interesting context in which to consider the properties of quadrilaterals (or triangles), and has a particular focus on the combinations of properties that are possible.

      This resource has comprehensive teachers' notes and resources, linked from the problem page. This includes possible approaches and key questions, as well as possible support and extensions.

      This is a great activity for pupils to play around with different criteria for triangles and see which combinations work well together and which don't work at all. The separate cards for triangles and quadrilaterals are also very useful, thank you

      Many thanks from France !

    • I used this to introduce the different types of triangles to my Year 5 class. They then had to write their own 'triangular thrillers' for homework. They loved it!

      Was so helpful.Helped me prepare the learners.

    • Geometry worksheet activity: Cut out the facts on triangles and quadrilaterals and put them in to groups: Always True; Sometimes True; Never True.

    • This is a rich Venn Diagram activity on angles in triangles, including isosceles, right-angled etc.

      To access all the Venn Diagram activities in this collection, as well as teaching notes, please visit: http://www.mrbartonmaths.com/venn.htm

      Here is why I love Venn Diagram activities so much:

      1) Students can always make a start. If they can think of a number/expression/object or whatever it might be, it has to go in one of the regions on the diagram, so they are up and running
      2) The more regions student find, the more challenging the task gets, which adds a nice element of differentiation
      3) They are incredibly versatile, and can be used for almost all maths topics for all ages and abilities
      4) They are easy to tweak by simply changing one of the circle labels if you find they are too difficult/easy
      5) Students can create their own as an extension task

      I hope you and your students enjoy them.

      New to the 'extra' uses of Venn - am immediately passing on to colleagues.

      The Venn diagram format works really well for this topic, and as has been said this is an excellent way of stretching pupils to think about shape properties. Thanks for sharing!
