This is a set of 160 flash cards of trinomials in the form of ax^2 + bx + c that has a values of 2 to 4 and c values ranging from 1 to 5. Each flash card has the answer key directly on the back when printed with the shorter side being the flipping side.
In my own classroom, I printed these on colorful cardstock (as shown in the picture), laminated the sheets, cut out each card, hole punched each card in the center of the left-hand side, and then used a ring binder to keep them attached. My students loved these and they will be used many times in the future!
If you want me to create more trinomials in this form, I certainly can! Just message me your suggestions.
