# Max Maths, Year 4, Try it, Carroll diagrams (2)

In the Max Maths Year 4 curriculum, students are encouraged to explore the properties of shapes through a 'Try it' activity involving Carroll diagrams. The task requires children to draw shapes that meet specific criteria in each section of a two-by-two grid. This particular exercise is found on page 101 of the workbook and helps pupils to categorise shapes based on whether they are two-dimensional and whether they have all straight edges or not.

The Carroll diagram is divided into four quadrants with two categories along the top: '2D shape' and 'Not a 2D shape'. The two categories along the side are 'All straight edges' and 'Not all straight edges'. Students are asked to draw examples of shapes that fit into each of the four resulting boxes. For instance, in the box that intersects '2D shape' and 'All straight edges', they might draw a square or a rectangle, while the box that intersects 'Not a 2D shape' and 'Not all straight edges' could include a drawing of a cone or a sphere. This activity helps students to understand and differentiate between various geometric shapes and their attributes.
