Learning objects Tessellate decorate: right-angled triangles

TLF ID L7786

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.



Educational details

Key learning objectives
  • 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.
Educational value
  • Demonstrates the properties of tessellations by providing models of different tessellations of the same right-angled triangle shape.
  • Provides multiple right-angled triangles for the student to arrange to replicate the modelled patterns.
  • Allows trial-and-error strategies and provides supportive feedback to the student.
  • Expands the pattern automatically to fill a large space and allows the student to see the continuous multi-directional nature of tessellations.
  • Includes a print option that captures the student's experiments in the free-play space.
