This set of cards uses the two special right triangles (30-69-90 and 45-45-90).
1. Post the cards around the classroom (either a set of 10 problems (hearts),
10 problems (clubs) or 20 problems (diamonds). The 10 set of heart problems focus
on basic 30 deg-60 deg-90 deg or 45 deg-45 deg-90 deg triangles. The 10 set of club problems focus
on using the more challenging 30 deg-60 deg-90 deg or 45 deg-45 deg-90 deg triangles. When you
use the 20 diamond problems you will use both sets of cards.
2. Assign different students to start at different numbers. Distribute copies
of the students recording sheet. Students can record the number of the problem
they are working on in the small rectangle in each section of the recording sheet.
When the work on the problem, they then go on a scavenger hunt to find the card
with their answer in the bottom right corner of a new card. If they can’t find
there answer they need to check their work again. When they find their answer on
a card, they record that number in the next square and solve the new problem.
Students keep working on problem for the allotted time.
3. The goal would be to complete as many questions as they can in the allotted
amount of time.
4. Awards can be given for the number of problems completed by each student.
