Strategies and Content Practice	Notes
Begin (prepare)	Review the 1-step problems, all four varieties, addition, subtraction, multiplication, and division. Make sure students have this prior knowledge. Remind students that the order of operation is done in reverse for solving algebra problems; Please Excuse My Dear Aunt Sally is up-side down. Check for prior knowledge.  Discuss if any have done 2-step problems; if so what do they recall?	Write on the whiteboard "Aunt Sallys Upside Down". Aunt Sally  (add or subtract first) My Dear (multiply or divide second) Excuse (exponents come third) Please (parenthesis come last)
Engage	Have students read pages 88 - 92. Read aloud same with students, emphasize definitions and examples. Show demonstration videos for Lesson 2-2 (above).	Try this online Algebra Tiles App to practice solving 2-step problems.
Assess (formative)	After example problems and videos, have students try to solve the Sample Problems below.  After students have had time to complete them, click on the Solutions link and go through the step-by-step process for solving each problem.  Repeat if necessary with additional example problems in the book and re-assess.
