1. Big ideas

1.1. Factoring and combining like terms

1.2. Simplifying expressions

2. Objectives

2.1. Rewrite algebraic expressions in different equivalent forms

2.2. Simplify expressions using strategies such as combining like terms, using distributive property and other operations with polynomials

2.3. Apply factoring techniques such as common factors, grouping, the difference of two squares, the sum or difference of two cubes to factor the expressions completely

2.4. When given a set of varying types of algebraic expressions, use appropriate tools strategically to solve or simplify those expressions

2.5. Make sense of problems, either by rewriting, simplifying or expressing in word, table, or area forms, and persevere in solving them

3. Scaffolding Strategies

3.1. Teacher models math principles for each of the objectives in this use (simplifying expressions using different techniques)

3.2. Teacher reads expressions in word form and students translate them into numeric form

3.3. Students break into small groups and practice matching expressions to their equivalent forms

3.4. Student groups present their solutions to the class, explaining the steps they took to rewrite/simplify the expressions

4. Student readiness / why I chose these strategies for my students

4.1. Students to observe me model the skills (visual and auditory learners)

4.2. Students practice initially using cut-out cards in small groups (kinesthetic learners; social learners)

4.3. Students get teaching experience by presenting their solving strategies and helping their classmates with the in-class exercises
