📌 Teacher Moves

• Deliver interactive modeling. Write the formula on the board.
• Show both Method A and Method B. Ask students which one they prefer and why. Highlight that division is often quicker!

🗣️ Teacher Script

"Look at this template. Placing numbers into designated buckets keeps our thoughts organized. If Area is 48, it goes in the left bucket. Length goes in the middle. The parenthesis holds the variable width."

❓ CFU Core Setup

"Why do we put parenthesis around \(x + 2\)? Because we are multiplying the entire width by the length, not just the \(x\)!"

🎯 LAP Look-For

Watch for students confusing where to write the area. Some write it as the length multiplier. Point out the color-coded borders.

Lesson 2: Area Word Problems

Guided Practice Answer Key

1. Garden: Area = 30, Length = 6, Width = \(x + 3\).

30

=

6

( x +

3

) Answer

Step 1 (Setup): \(30 = 6(x + 3)\)

Step 2 (Divide): \(30 \div 6 = 5 \rightarrow 5 = x + 3\)

Step 3 (Subtract): \(5 - 3 = x \rightarrow x = 2\)

Final Answer: x = 2

Sentence Explanation (Completed): "To solve for \(x\), I first divided the total area 30 by the length 6. This gave me 5. Next, I subtracted 3 from both sides to find that \(x\) equals 2."

Guided Explanations Note: Sentence frames are vital SPED writing scaffolds. Ensure students read the completed sentence frame aloud to embed conceptual sequencing.

📌 Teacher Moves (We Do)

• Complete the template together. Write the numbers in with red or blue marker on the smartboard.
• Ask a student to read the sentence helper aloud with the numbers filled in.

🗣️ Teacher Script

"We have Area 30, Length 6. Let's place 30 in the Area bucket and 6 in the Length bucket. If we divide 30 by 6, what number do we get? Five! Correct. Put that on step 2!"

❓ CFU Process Check

"Why did we subtract 3 at the end? Because the opposite of plus 3 is minus 3!"

🎯 LAP Look-For

Verify students are writing the inverse operation step (\(-3\) under both sides) clearly to maintain balance.

Lesson 2: Area Word Problems

Independent Practice Key

Question 1: Area = 40, Length = 5, Width = \(x - 2\)

Setup: \(40 = 5(x - 2)\)

Divide by 5: \(8 = x - 2\)

Add 2: \(8 + 2 = x \rightarrow x = 10\)

Answer: x = 10

Answer

Question 2: Area = 60, Length = 10, Width = \(x + 4\)

Setup: \(60 = 10(x + 4)\)

Divide by 10: \(6 = x + 4\)

Subtract 4: \(6 - 4 = x \rightarrow x = 2\)

Answer: x = 2

Answer

Question 3: Multiple Choice Setup

Correct Choice:

B) \(72 = 8(x + 1)\)

Remediation Tip: If students get \(x = 6\) for Question 1, they likely subtracted 2 instead of adding 2. Remind them that the opposite of subtraction is addition!

📌 Monitor & LAP Circulation

• Path: Target SPED subgroup first, then general class.
• LAP: Spot-check Q1 setup immediately. Give a non-verbal thumbs-up if setup is \(40 = 5(x - 2)\).

🎯 LAP Prompt Guides

Stuck: "What are our three buckets? Look back at Page 2."

Sign Error: "Look at Question 1. Is it minus or plus? What is the opposite?"

⚠️ SPED Contrast Cue

Point to the minus sign in \(x - 2\) on student sheets if they are blindly adding numbers.

🚀 Mastery Goal

Aim for independent setup success on at least 2 out of 3 problems!

Lesson 2: Area Word Problems

Exit Ticket Answer Key

Question 1: Tile Area = 18, Length = 3, Width = \(x + 2\)

Setup: \(18 = 3(x + 2)\)

Divide by 3: \(6 = x + 2\)

Subtract 2: \(6 - 2 = x \rightarrow x = 4\)

Equation:

\(18 = 3(x + 2)\)

Value of x:

x = 4

Answer

Question 2: Sentence completed

"To solve the area equation \(18 = 3(x + 2)\), I can start by dividing the total Area, which is 18, by the length, which is 3."

Grading & Assessment Rubric:

• 3/3 points: Complete mastery! Student correctly solves, sets up, and explains.
• 2/3 points: Setup correct but math arithmetic error (e.g. division/subtraction mistake).
• 1/3 points: Reteaching on equation mapping required.

📌 Teacher Moves (Silent Work)

• Initiate silence. Point to the timers and rubrics.
• Allow students with IEP read-aloud accommodations to hear questions whisper-read.
• Collect and sort papers instantly at the door.

🗣️ Teacher Script

"It's time to show what you've learned today. Silent individual work on page 5. You have 5 minutes. Use your formula templates to help you solve. Begin."

📊 Action Plans

Divide stacks of graded tickets. Students scoring 1/3 need immediate small group pullout in the warm-up tomorrow.

🎯 Exit Goal

Verify that students do not blindly write "x = 4" without filling in the equation setup box first.
