This set of I Have... Who Has... cards can be used to review the use of the Pythagorean Theorem. The activity will engage all students in solving the problems.
The set of cards can be divided into sets of 15, 20, or 25 cards. So it can be used in a class with 15 students, 20 students, or 25 students. (Or some students can be given more than one card.) Each students gets a card and anyone can begin the activity by reading their Who Has ... All the rest of the students listen to the problem and solve it. If they have the answer, they announce the answer by saying "I have..." and then read the new question. The activity continues until the last person reads their question. The answer to the last card will be on the first card that was read.
It is easy to sort the cards into the various size sets by using either the heart (25), diamond(20), or club(15) at the bottom of each card.
This activity is appropriate for high school geometry students. The questions include Pythagorean Triplets, 30-60-right triangles, 45-45-right triangles and other right triangles.
Encourage all students to record their solutions to each problem on a special Student Recording Sheet.
This activity includes two sets of cards: one with graphs and one without graphs and a master copy of all cards.
