The Class Activity -45-45-90 Triangles was created by Pupsaroni Puzzles for use in a classroom studying 45-45-90 triangles and their properties. Typically this is an Algebra or Geometry classroom. This specific activity was made to help students work on the shortcuts for finding sides of a triangle if they knew it was a 45-45-90 triangle.
Card 2 can be printed out on different colored cards for the
students. Card 3 can be used as a cheat sheet.
Cards 4-43 can be printed and posted around the classroom or the hall.
Cards 44-83 are answer cards.
Students take their cards and cut them out. Students are
instructed not to put their color card where there is already a card of that color, and they are not to put a number card where there is already a card of that number. This ensures students look at a variety of different problems.
This activity is great for students who want to work alone or in pairs. Pairs give students an opportunity to discuss how to solve problems. This activity also allows students to get up and move around. It can be used multiple times if the cards are laminated. Students can tape their cards up next to the triangles that they are working on. Those cards with their triangles can then be discussed in groups or in as a class.
