*Note: Prior knowledge of factoring quadratic trinomials, with leading coefficient of both 1 and 2,3,5 is needed for this review.
I have worked it as such: Have a large white board and use the quadratic expressions on the board, and give the students only one minute to factor it, and find it on their card (or not!) before moving on to the next card. They need to be reminded that via the Commutatitve Property of Multiplication that their answer may be written 'in reverse' order of the parentheses and that is OK. I made 32 sheets so I can have a class set, and the students can even get a different card each game. By the way, one of the cards is the "Difference of Two Perfect Squares" just to keep the game more interesting!!
Also included is a sheet that is the ultimate answer key with ALL answers to the cards/balls. On each card, in the upper right corner, is the answer to the quadratic expression you would write on the white board. Cut up the cards, mix them in a box (like bingo balls in a machine), and have fun! Each bingo card is unique! And like in real 'Bingo', not every trinomial card answer is found in every bingo card. About 2 of every 3 total factored answers are found on each card, which makes it more real. Feel free to message me for more clarity!
And if this website allows, also watch the video I used for years to promote this activity with my students!!
