Unit description and duration
This two-week unit develops student knowledge, understanding and skills of how new shapes can be made by joining (combining) and breaking apart (partitioning) existing shapes. Students are provided opportunities to:
two-dimensional (2D) shapes can be made by joining (combining) and breaking apart (partitioning) existing shapes
shapes have attributes that are necessary for classification as that shape (features of triangles, circles, squares, rectangles)
necessary attributes are called features
shapes and objects can be halved in different ways
new shapes can be created by adding or removing sides
numbers, like shapes, have smaller numbers hiding inside of them (numbers 0 to 10)
Student prior learning
Student prior learning
Students would benefit from prior experience with:
opportunities to investigate shapes through playing with pattern blocks, geoboards, paper folding, cutting and building with solid objects
noticing and using attributes to sort and classify shapes
distinguishing shapes by their features
using mathematical language in relation to shapes.
