28 cards to match into sets of 4. Mainly matching equations, but there are some graphs and verbal descriptions thrown in too. Includes answer key for teacher and student grid to record answers. Easiest grading ever, and NO PREP for teacher! The students will talk talk talk about math while they are trying to match the cards.
I use this as a cooperative activity and do not allow my students to use their notes nor technology. In randomized pairs, my students took about 30-45 minutes to do this activity. I allowed one “hint” on my part per pair when about 15 minutes remained. I allowed each pair to point to one box in the grid and I wrote in a correct letter.
What my students knew: How to tell if a parabola opens up or down, how to find the y-intercept, how to find rational x-intercepts, how to find the axis of symmetry, how to find the vertex by first finding the axis of symmetry or by finding the x-intercepts and knowing it is located exactly between them.
What my students did not know and still could match successfully: completing the square, quadratic formula. This was the first time I took away their technology with within the unit on factoring and/or quadratic functions.
I grade their work and count it as a quiz. I do at least one of these matching activities per quarter.
The teacher should: Make a copy of the activity, cut up the cards, and do it him or herself first. Then, make a classroom set of cards (15 zip-lock bags, 28 brightly colored cards in each bag) and make enough of the half-sheet answer grid to give one to each pair. Monitor the activity after some very brief remarks. The students will figure it out!
Without using technology, match the 28 cards. There are seven lead cards to get you started “Card 1”, “Card 2”, and so forth. Record the letters of the three remaining cards in the blanks to the right of the card with which they match. Attach all of the work you do to this answer sheet. Have fun!
