This lesson is designed for 1st Class, according to the Irish Education System.

Students will build on their understanding of shapes and basic geometry. They will encounter many new shapes with different characteristics and we introduce the terminology of vertex , edge and region . We will also examine 3-D shapes. Students have the opportunity to design their own shapes with unique properties.

The life and work of Leonhard Euler will be discussed. The Euler characteristic will allow students to practice addition and subtraction. Finally, we have developed several computational tools on scratch that should reinforce the lesson content. There is also a quiz for students to test their understanding of the topic.
