This activity explores the equivalence of algebraic expressions in expanded and factored form, using patterning with CAS to expose commonly held student misconceptions.
The big algebraic mathematical ideas this activity explores are equivalence and symbol sense. More precisely, the activity speaks to the following curriculum expectations: expand and simplify second-degree polynomial expressions involving one variable that consist of the product of two binomials [e.g., (2x + 3)(x + 4)] or the square of a binomial [e.g., (x + 3)2 ], using a variety of tools (e.g., algebra tiles, diagrams, computer algebra systems, paper and pencil) and strategies (e.g. patterning)

Lessons are reviews of notes from the textbook.
Practice questions are extra material for students to use.
Lots of space is left between the question and answer to give students the opportunity to explore the question before jumping to the result.
TI-NSPIRE activities are fun problems to enhance the learning of graphing.
Links are given as lesson plans.
