Warm-Up 1
Day 5: Week 1 Review
Review integers, rational numbers, percents, and problem-solving habits from Days 1-4.
Student Goal
I can use what I practiced this week to solve mixed review problems.
Why It Matters
Mixed review helps students choose a strategy instead of only practicing one skill at a time.
Warm-Up
Warm-Up 2

Short Lesson
Standard Focus
NC.7.NS and NC.7.RP readiness
Student-Friendly Standard Goal
I can decide which strategy fits a problem and explain why my answer makes sense.
- Mixed review means you first identify the type of problem before solving.
- Look for clues: signs may point to integers, decimals and fractions may need comparison, and percent symbols mean part of a whole.
- After solving, check the reasonableness of the answer using estimation or the real-world context.
