Introduction & Warm-up
Greeting & Context Setting
Display the first slide and greet the "Expedition Team" (the students).
Introduce the topic: strengthening algebraic foundations.
Quickly preview the roadmap: factoring, distributing, solving for x, and equivalent expressions.

Direct Instruction & Guided Practice
Modeling & Concept Review
Navigate Slides 2-5, explaining each concept with the provided examples.
Work through 1-2 problems per concept together on the board.
Key Tip: Emphasize the "GCF" in factoring and the "rainbow" distribution method. Watch for sign errors in distribution!

Independent Practice
Problem Practice Patrol
Distribute the worksheet and the Time Travel Tally activity sheet.
Instruct students to work independently.
Circulate to check for common pitfalls (e.g., forgetting to divide both sides in multi-step equations).
Remind students that "showing work" is their climbing gear—they can't summit without it!

Wrap-up & Review
Debrief & Solutions
Bring the class back together to review 2-3 of the most challenging problems.
Address common misconceptions identified during circulation.
Assign any unfinished problems as homework or extension practice.
