Right Triangle Applications.
This activity is intended to be used in a Geometry, Algebra 2, or Trigonometry class. Look at the thumbnails and the preview to make sure these problems are appropriate for your students.
The problems use sine, cosine, and tangent to solve for an unknown side. They are one process problems, i.e., you do not have to solve one triangle in order to find a part of another. Problems include degrees and minutes, angle of elevation, angle of depression, typical kite, balloon, ladder problems, and a few not so typical.
*Two sets of 15 task cards, one with QR codes
*Student response sheets
*Worksheet for using as HW, enrichment, or assessment
*Quiz for follow up on activity
There are multiple ways to use these task cards in your classroom. Students can work alone, randomly pair up, or work in small groups. When students work in pairs or small groups, give as many task cards as there are students. This way they can help each other and work together. After a few minutes, depending upon the difficulty level and your experience, each group passes their cards to the next group.
You may also set up math centers with these cards.
If you have more than one class, this lesson gives you great flexibility; one class can use the Task Cards with QR, one class without, another class as a worksheet. Use half the Task Cards in class and the other half as homework.
