Triangles don’t need to be tricky for your students! Ā This week, my class tackled classifying triangles and really enjoyed the whole process. Ā The recipe for success involved some triangle foldables, interactive notebooks, an easy-to-follow anchor chart, and some practice. Ā It really was Triangle Classification Made Easy!

First, we added some mini triangle classification charts from my 2-Dimensional Foldables Packet to our interactive math notebooks. Ā I also displayed this anchor chart at the front of the room as we talked about the 2 ways to classify triangles.

Then, we cut out, colored, and labeled the first set of triangle foldables. Ā This set required students to classify the triangles according to length of sides: Scalene, Isosceles, and Equilateral. Ā Then, students glued the foldables onto the next page of their notebooks.

Next, the students did the same thing with the second set of triangle foldables. Ā This set was classified according to types of angles: Acute, Obtuse, and Right.

Now that the students were more familiar with the 2 ways to classify triangles, they were ready to practice. Ā I drew a triangle on the Smartboard and had students classify it in both ways and write their responses on their dry erase boards. Ā Overall, they were quite successful!

I took the students to a more difficult level by asking them to draw a certain type of angle, classified both ways. Ā For example, they had to draw a scalene, acute triangle or a scalene, obtuse triangle. This proved to be more difficult for them, but I love challenging my students and seeing them rise to the occasion!

You can also use triangle foldables in your students’ notebooks. Ā Have students make their own, or you can find my pre-made foldables in my best-selling 2-Dimensional Shapes Foldables Packet at my TPT Store.
