Exploring Triangles with Geoboards
This week in math we had a blast exploring triangles. It is important for students to understand that triangles are 2-D closed figures (meaning all lines connect) that have 3 straight sides and 3 vertices (our fancy word for corners). Our friends did a fantastic job creating different types of triangles on their Geoboards. Geoboards are plastic and have small pegs on them which hold rubber bands. Students manipulate the rubber bands to make different shapes--and in this case, we created triangles. The main goal of this lesson was to make sure students understand that there are different types of triangles. Not all triangles have equal sides, they can be large or small, and can be positioned many ways. They exercised their brains together and learned a lot from this activity!
