New Class: Two and Three Dimensional Geometry

Class: Two and Three Dimensional Geometry

Age/Grade: appropriate for grades 3-6, ages 8-11(approximately).

Course Description: Students will "develop more precise ways to describe, classify, and make generalizations about 2- and 3-dimensional shapes. They'll identify properties of shapes and then link those properties to specialized geometric vocabulary like angles, sides, faces, edges, and so on. They will construct and sketch shapes, compare and discuss their attributes, classify them, and develop definitions for these new ideas.

Students will communicate their geometric conjectures and arguments in the context of problem solving. They'll fold and cut a square piece of paper to make a set of tangrams and then use spatial reasoning to investigate the relationships among the tangram shapes, using combinations of pieces to create familiar polygons.

[As time allows] students will use also use geoboards, geoblocks, and polygons formed with toothpicks to build understanding of congruence, similarity, and symmetry." (The curriculum and course description are taken from Bridges in Mathematics.)

Here are class examples from last year. (This is not the same content as the geometry class I taught last year.)

5 sessions, 2 hrs. each
October 18, 25, November 1, 8, 15

  1. I wish sometime you would put your classes on Fridays so the huge group here in Oregon City could make use of them. Many of us use the homeschool/charter school based here in OC. so we cant do classes anywhere else Monday -Thursday. Fridays there are no classes at the charter school. I would love to send my son to this and am sad it never works out. :(

  2. Hi Mrs. Darling!

    Good to know that. I don't have a strong preference between Monday and Friday.

  3. HI there!! I am your newest follower from the blog hop. I think it's an old link so I'm extremely late but here none the less:) Lovely blog:) You can find me at
