Our manipulative began as an idea stemming from what we learned about our students’ mathematics, which we learned about in our interview with them. We wanted them to learn more about numbers, so we thought it would be a great idea to apply touchpoints to geometric figures. The geometric figures we designed are a square, oval, circle, rhombus, diamond, trapezoid, pentagon, hexagon, an isosceles triangle, equilateral triangle, and a house. We wanted to use them to give students a reason to count. We would ask them to count the sides and the vertices, and maybe see if they could find a relationship between the two numbers.
