This set of I Have... Who Has... cards can be used to review the student's knowledge of linear equations, x- and y- intercepts, and slope. The activity will engage all students in solving the problems.
It is easy to sort the cards into the various size sets by using either the heart (25), diamond(10), club(15), or spade(20) at the bottom of each card.
The set of cards can be divided into sets of 10, 15, 20, or 25 cards. So it can be used in a class with 10 students, 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.
This activity is appropriate for high school algebra students.
This activity includes two sets of cards: one with graphs and one without graphs and a master copy of all cards which includes all solutions..
