Fun with pattern blocks... 2D geometry continues

Today in class we began creating pattern block designs.

We examined the attributes of each of the pattern blocks before we began. We discussed the following  terms for each shape:
- angles
- parallel lines
- number of sides and vertices
- parallelograms
- polygons
- quadrilaterals
- right angles
- lines of symmetry

One example is the triangle. It is a polygon. It has 3 vertices, sides and lines of symmetry. It is not a quadrilateral or parallelogram. It has 3 angles less than 90 degrees. 

Our activity:
We designed our own figures out of the pattern blocks and then tried to see what was the least amount of blocks needed to cover our design. Then we tried to see what was the most amount of blocks needed to cover our design. We realized that using the triangles to cover helped us see the most amount of blocks needed, and the trapezoid and hexagon were the blocks that helped us see the least amount of blocks needed to cover our designs.

Check out our work.
