Product Description
This Class Activity - Trig Functions was created by Pupsaroni Puzzles for use in an Algebra or Geometry classroom that is studying using trigonometric functions. There are several triangles for students to practice or review or both.
Cards 2-3 should be printed out for the students to cut out and work the activity. Card 4 is more of a reference material card. It can be used before the activity for explanation, or after the activity for clarification, or during the activity for reference.
The rest of the cards have been divided into four sets. Sets A and B have the measure of one side and both angles given so students can solve for the measures of the other two sides. Sets C and D have the measures of the sides only so that students may solve for the angle measures. Sets A and C use the same general triangle and have an answer key. Sets B and D use the same general triangle and have an answer key. The number at the top right of the cards corresponds with the key cards so that the cards are easier to check.
Student cards 2-3 should be printed out on multiple color paper. Students cut out the cards. Students are instructed that they can not use the same color card at the same trian-gle (in hopes that students will look at more different problems), and they are not allowed to use the same card at a triangle that anyone else has used.
Set A includes cards 5-55, Set B includes cards 56-106, Set C includes cards 107-157, Set D includes cards 158-208, and the answer cards are cards 209-310.
The triangle cards for the sets should be taped up in the classroom or the hall in some ran-dom order, and students choose which triangles to work. The cards can be varied per class or section to keep students from all having to work the same triangle problems.
Students can work together to engage in purposeful discussions about the trig functions and how to solve the cards appropriately. Students also enjoy the choice and the freedom to move around working the problems. This can be used as a class activity or as a station for students to practice. It can be used and re-used as students can be given more cards to prac-tice more problems. If this is set up as a station that kids are continually using for practice, the cards can be laminated and marked with a dry erase marker. Technology can also be used if students snap a photo of their practice work and submit that work.
