Great set of self-checking exercises for your students -- they will love working this group of mixed factoring problems. Student must factor polynomials (mixed methods) and then hunt for ONE of the factors to advance in the circuit. 20 problems total. Your students will be engaged and will not get up when the bell rings! The problems are progressive in nature (build from easiest to hardest) and so the circuit is great for differentiated instruction. Perfect for Algebra I or as a review for Algebra II or college algebra.
