Classifying Triangles Card Sort

Classifying Triangles Card Sort
Product Description
This sorting activity will strengthen students’ skill in sorting triangles into the following types of triangles categories: Equilateral, Isosceles, Scalene, Equiangular, Right, Acute, and Obtuse. Students will cut out the 18 included triangles and use the given information on each triangle to sort it into the correct spot on the chart.

• With this product you get a version of the chart with and without QR codes so you can choose which version to use in your classroom. The QR Codes next to the different types of triangles give the definitions of each type of triangle. QR Code readers are free in both the Android & Apple app stores. Once downloaded they do not require an internet connection to work. The QR codes are not necessary to complete the activity but are a fun extra to have in student notes.

• The fact that the angles in a triangle add up to 180° (Triangle Sum Theorem) is required for some of the triangles. If doing this with younger students I recommend you quickly introduce that concept and find the missing angles in the triangles before letting the students complete the activity.

• There are 5 “Not Possible” cards that students will put in 5 of the squares on the chart. When classifying triangles students are expected to classify triangles into the most specific category. Thus, “Isosceles & Equiangular” is marked as Not Possible because any isosceles triangle that is equiangular is also equilateral so the most specific category would be “Equilateral & Equiangular”.

The letters inside each triangle make for easy teacher checking by just checking the letter. Answer key is included.
