House 43 Digest Online

This week House 43 will begin our second week exploring the attributes of 2-dimensional and 3-dimensional shapes. The guiding question for this series of investigations is: “How do we define 2-dimensional and 3-dimensional shapes?” Children are experimenting with shapes using geoboards and playing games, which require pairs of children to describe shapes to each other without using the label of the shape. As a class, we are developing a classroom chart to display the attributes of polygons (2-dimensional) and, later in the week, polyhedra (3-dimensional shapes).

Here is an example of House 43’s list of attributes for a rectangle:

- 4-sides

- 2 sets of parallel (sides that have the same distance between them) sides

- 4 corners

- Each set of parallel sides is of different lengths

- the parallel sides are of equal length

- 4 right angles
