Triangle Theorems & Properties - Practice / Review:This sorting activity will help your students practice using properties of triangles. They will classify each triangle as equilateral, isosceles, scalene, or impossible using cards with a mix of given information (diagrams, side lengths, angle measures, and ordered pairs for vertices on a coordinate plane) so that they have to use a variety of skills and concepts to sort them properly.The following concepts are used to determine types of triangles:* Distance Formula* Base Angles of Isosceles Triangles* Triangle Sum Theorem* Exterior Angle Theorem* Triangle Inequality Theorem* Vertical AnglesHere's what's included:- 4 quick-fold pockets to hold sorted cards- 30 cards with a mix of diagrams, side lengths, angle measures, and ordered pairs representing vertices- 4 "answer cards" that list which cards should be in each pocket- optional "sorting mat" for those who prefer a learning station formatStudents will cut out and sort the cards into the correct pocket (equilateral, isosceles, scalene, or impossible/not a triangle). The pockets fit well on an interactive notebook page.Then, hand out the answer/check cards. After students have verified that their cards were sorted correctly, the answer cards can be tucked into the back of each pocket. Students can re-do the activity as review any time. ___________________________________________________ Reviews from other Teachers: - The perfect activity to reinforce this concept! - This was an excellent resource for practice! Some tricky problems that made students really think. Thank you!! - Card sorts are so much fun with high school kids. Some of them think they are above hands on activities but then they get really into it. - The kids have really enjoyed these and they are great for them to reference. - This was a fun way for my students to practice their knowledge of types of triangles. Students were required to use knowledge previously learned, which I love. It is an awesome way to review concepts while still continuing on with concepts. Excellent resource. - A great way to practice and review multiple topics! - The instructions are very easy to follow. This is a great hands-on activity. Thank you for creating it! - Cards sorts are my new favourite - I love the thinking and discussions that occurs when we do these.
