Quadratic Formula Discriminant Sorting Activity - printable PDF and digital

What others say

"This was a great hands on activity for students. The free reference sheet from her shop is a great addition for struggling students."

Courtenay D.

Description

Students determine a, b and c from a quadratic function, sketch a parabola between 3 points or simplify a written discriminant before sorting into one of the 3 categories in this activity. There are 20 cutouts to sort. Students get practice with identifying A, B and C and evaluating b^2 - 4ac correctly, which can sometimes be tricky!

This download includes both a printable and digital version of the activity. The digital version is in GOOGLE Slides.

Students sort their cards onto a sheet with boxes for "1 real zero", "2 real zeros" and "no real zeros" to organize their thoughts and then complete an answer sheet to submit.

My students did not particularly like this activity. Many said it was boring and chose to stop engaging in completing it.
