What do we already know about shapes?

First, the students used whiteboards and markers to draw all the shapes they know. 

Next, we offered a challenge with toothpicks. 


Tom is making shapes with ’12’ toothpicks. Using all of the toothpicks (12), create 3 different shapes he could make. How many other combinations can you find?

Student Responses:


Exploring 3 Dimensional Shapes


Create the 4 shapes using clay, Lego, play dough and toothpicks, paper or card.

Big Ideas:


  • geometric shapes and associated vocabulary are useful for representing and describing objects in real-world situations
  • changing the position of a shape does not alter its properties
  • specific vocabulary can be used to describe an objects position in space
  • shapes can be transformed in different ways
