This is Day 1 of how I will be teaching Triangles this week.
With the new Texas standards this year, my 6th graders are supposed to already know the types of triangles, but they do not. So I really cannot spend any days on teaching classification of triangles, but I will.
Inquiry Question: How can triangles be classified or grouped?
Engage: Ask students where they have seen triangles or how could they be useful.
Explore: In groups: Cut out a sheet of triangles of all types and find 3 ways to group the triangles.
Allow students to share how they classified the triangles. (I expect that some students will already know the types of triangles, so this will be a way for me to assess who knows and who doesn't.)
After listening to student ideas, have them try again and find 3 other ways to group the triangles.
Explain: Glue notes into ISN giving definitions of triangles and watch this video.
Elaborate: Using the app Geoboard, students will make and explain all the types of triangles.
Evaluate: Write triangle riddles: I have 3 60 degree angle, I have 3 equal sides. What am I?
and a quick 4 question exit ticket.
This is the plan. I'll report back after execution.
