We are ending our 2nd/3rd grade math learning how to recognize and characterize shapes by their attributes and properties. Our first lesson was describing two-dimensional shapes according to their number of sides or angles. Our students were encouraged to use precise language when describing the shapes. For example, they described a pentagon as a shape with 5 sides and 5 angles. We also used various tools to help the students engagement such as geoboards and straws to make shapes. The students are enjoying this unit as they are able to have some fun with the shapes while learning.
The students were given a challenge to create as many shapes as they can with 10 straws.
