# Big 10 Solving Quadratic Equations by Factoring Worksheet

Your students will enjoy this self-checking solving quadratic equations by factoring worksheet which uses the Big 10 review activity structure.

Earlier this week, I shared a Big 10 Worksheet over Percents for middle school students (or a much-needed review of percents for my high school statistics students…)

*This activity was originally published in the Fall 2023 Oklahoma Council of Teachers of Mathematics Newsletter. *

## About the Big 10 Worksheet Structure

A few years ago, I started teaching AP Calculus AB. It has been a wonderful learning opportunity for both my students and me. I am continually blown away by the number of free activities and resources that are shared by members of the AP Calculus community.

I realized that several of the practice activities that were shared in the AP Calculus Teachers Facebook group could be modified for use in math courses of all levels. One of

these commonly used activities for teaching AP Calculus is called “Big 10.”

The majority of the Big 10 activities I have used in calculus have been written by Bryan Passwater. Vicki Carter has also been creating some Big 10 Activities for AP Precalculus. There is also a collection of AP Calculus Big 10 Activities that can be downloaded on TPT from CR Calculus.

A Big 10 worksheet has 10 questions. At the beginning of the worksheet, there is a box containing either the numbers 0-9 or 1-10.

Students cross out a number in the box after solving each problem. If done correctly, students will have all 10 numbers crossed off without any repeats.

I like these activities because they are self-checking, and they aren’t too tricky to put together yourself if you are needing a review activity for a certain topic. You simply need to come up with 10 questions with answers of either 0-9 or 1-10.

## Worksheet Instructions

Complete each problem. Cross off the answer in the box below.

If done correctly, you will have all 10 numbers crossed off with no repeats.

This worksheet features 10 different quadratic equations for students to solve. Each of these quadratics can be solved by factoring. The worksheet does not specify that students MUST solve the quadratic equations by factoring.

Students could use the quadratic formula to solve these equations if they preferred to. For me, however, I would most likely include this worksheet in my solving quadratic equations by factoring section.

These problems are intended for students at an Algebra 2 level or above. I have not personally used this activity with students yet. I created it to be featured in the Oklahoma Council of Teachers of Mathematics quarterly newsletter, and I decided I wanted to share it with you as well!

## Puzzle Solutions

I intentionally do not make answers to the printable math puzzles I share on my blog available online because I strive to provide learning experiences for my students that are non-google-able. I would like other teachers to be able to use these puzzles in their classrooms as well without the solutions being easily found on the Internet.

However, I do recognize that us teachers are busy people and sometimes need to quickly reference an answer key to see if a student has solved a puzzle correctly or to see if they have interpreted the instructions properly.

If you are a teacher who is using these puzzles in your classroom, please send me an email at sarah@mathequalslove.net with information about what you teach and where you teach. I will be happy to forward an answer key to you.

Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, as fun activities in their workplace, or as a birthday party escape room.
