Mathematics
Factoring Basics: GCF, Trinomials, and Zero Products
Students factor out the GCF, factor simple trinomials and differences of squares, solve quadratics with the zero-product rule, and find factoring errors.

Mathematics
Factoring Trinomials: Factor, Expand and Catch the Error
Students factor eight quadratic expressions, check by expanding, and find the mistakes in three sample factorizations.
Mathematics
Limits on Paper: Tables, Patterns, Algebra
Students estimate limits from tables of values, compare left and right limits, and find limits by substitution and factoring.
