Decorate a room in a house with patterns made of right-angled triangles. Choose a part of the room to decorate. Select a tessellation of right-angled triangles to make. Copy the pattern and see it cover part of the room. Finish decorating the room with two more tessellations. Create your own designs with the right-angled triangles in the play space. This learning object is one in a series of eight objects.
Objective
Students describe a tessellation as a pattern that has no gaps.
Students use right-angled triangles to create the same tessellation as one displayed in a virtual sample book.
