Constructive Triangles - Triangular Box
Use of this material makes the child aware that all polygons can be made with triangles. This activity prepares the child for geometry.
- Invite the child to the lesson. Name the work and show them where it is on the shelf.
- Unroll a large mat (or put two smaller mats side by side).
- Take the box of triangles to the mat.
- Lay the triangles so that the ones that go together are in columns.
- Slide down the bottom triangle for the first shape.
- Trace over the black line on it with your index and middle fingers.
- Trace the black line on the corresponding triangle.
- Slide down the second triangle so the black lines meet.
- Do the same with the other shapes.
