In math this term we started off learning about shapes with Division 2 and 4. It's been super fun and the students have learned a lot. Below is an outline of the curriculum for Grades 1 and 2.
Grade 1 Big Idea
Objects and shapes have attributes that can be described, measured, and compared.
2D shapes and 3D objects:
· sorting 3D objects and 2D shapes using one attribute, and explaining the sorting rule
· comparing 2D shapes and 3D objects in the environment
· describing relative positions, using positional language (e.g., up and down, in and out)
· replicating composite 2D shapes and 3D objects (e.g., putting two triangles together to make a square)
Grade 2 Big Idea
Objects and shapes have attributes that can be described, measured, and compared.
2D shapes and 3D objects:
· sorting 2D shapes and 3D objects, using two attributes, and explaining the sorting rule
· describing, comparing, and constructing 2D shapes, including triangles, squares, rectangles, circles
· identifying 2D shapes as part of 3D objects
· using traditional northwest coast First Peoples shapes (ovoids, U, split U, and local art shapes) reflected in the natural environment
Below are photos of children working together in groups to sort shapes into 2 groups, then 3, and so on. After each sort, teachers came and guessed what attributes were used as the sorting rule. Some were really tricky to guess. My brain worked hard that day!!
Once the students had a grasp of some of the mathematical language used to describe shapes, they built 2D and 3D shapes with plasticine and toothpicks.
Another day, students were challenged yet enjoyed making figures from this website.
