The Power Reveal (Exponents)

Focus on the Expansion Rule. Do not use mental math yet.

Script: "Exponents are just instructions. The big number is the actor, and the little number is the boss. If the boss says '3', you make 3 copies of the actor and multiply them."

Minutes

The Buddy System (Radicals)

Introduce roots as "Finding the Twins." Use the factor-pairing visual.

Script: "A radical is like a locked room. To get out, you need a twin. If you have two 5s, they pair up—one escapes the room, and the other disappears. If you're a loner, you stay inside."

Minutes

The Build (Guided Practice)

Distribute the Radical Rescue Worksheet. Monitor expansion and circling.

Support: "If they get stuck on factors, point to the Factor Finder Reference. Don't let them guess; encourage them to write out every multiplication dot."

Common Trap

Students will try to multiply the base by the exponent (e.g., \(2^3 = 6\)).

The Fix:

Force the physical expansion step for every problem. 'Show me the three 2s' before they calculate.

Intervention Scaffolds

• Use colored highlighters to circle 'Twins'.
• Physically cover the 'loner' numbers with a finger to show the simplified version.
• Keep the Perfect Square list visible at all times.
