Modeling Question 10 (Pipe Subtraction)
Teacher Script
Read: "Builders, look at Question 10. We have a pipe that is \( 12.5 \) meters long. We are cutting off \( 4\frac{3}{4} \) meters. The word 'remaining' is our job-site keyword—it tells us we're subtracting."
Model: "I see a decimal and a fraction. I'm going to convert \( 4\frac{3}{4} \) to a decimal. I know \( \frac{3}{4} \) is three quarters, or \( 0.75 \). So, \( 4\frac{3}{4} \) becomes \( 4.75 \)."
Process: "Now, I set up my subtraction: \( 12.5 - 4.75 \). I MUST line up the decimals. I'll add a placeholder zero to \( 12.5 \) to make it \( 12.50 \). Now I can subtract. I'll need to regroup across the 5 to subtract that 5 in the hundredths place."
Think-Aloud Targets
Keyword 'remaining' = Subtraction.
Benchmark conversion (quarters).
Placeholder zero for place value.

Guided Question 11 (Window Width)
Interactive Discussion
Prompt: "Question 11 asks for the total width of two window panels. One is \( 2.8 \) feet and the other is \( 3\frac{1}{5} \). Talk to your teammate—what operation are we using?" (Wait for: 'Addition').
Guide: "Now, let's convert \( 3\frac{1}{5} \). I know \( \frac{1}{5} \) is \( 0.2 \). So \( 3\frac{1}{5} \) is \( 3.2 \). Let's add: \( 2.8 + 3.2 \). What is the sum?" (Wait for: '6.0').
Validation: "Since this is multiple choice, we look for \( 6.0 \text{ ft} \). We must be careful with our place value alignment to ensure we don't pick a distractor like \( 5.6 \) or \( 6.2 \)."
You Do
Independent: Site Report (Concrete Mixing)
Monitoring Prompt (Day 1 Activity)
"As students work on the 'Site Report: Concrete Mixing' problem, check their strategy. Are they adding the used amounts (\( 3\frac{1}{4} \) and \( 2.75 \)) first? If they say \( 3\frac{1}{4} \) is \( 3.14 \), correct them: 'A quarter is \( 0.25 \), so \( 3\frac{1}{4} \) is \( 3.25 \).'"
Structural Verification
"Check their subtraction: \( 8.5 - 6.0 \). If a student gets \( 2.5 \), they have identified the correct amount remaining. If they stop at \( 6.0 \), ask: 'Is that what is left in the truck, or what the crew already used?'"
MISCONCEPTION RADAR
The "Whole Number" Alignment
On Question 11, students might align the 2 and 3 incorrectly. Emphasize lining up the decimals to keep tenths with tenths.
The "Regrouping" Slip
In \( 12.50 - 4.75 \), students often forget to regroup from the 5 (making it a 4) to give to the zero. Check for answers like \( 8.75 \).
Incorrect Quarter Code
Common error: \( \frac{1}{4} = 0.4 \) or \( \frac{3}{4} = 0.34 \). Refer back to the Anchor Chart 'Conversion Code' frequently.
THE FINAL DEBRIEF
Gather the team and ask these three "Exit Questions":
1
"In Question 10, why did adding a 'placeholder zero' make the subtraction safer?"
2
"If the architect in Question 11 wanted the answer in fractions, would it be easier to convert the \( 2.8 \) feet or leave the \( 3\frac{1}{5} \) as it is?"
3
"What is the most important step before you start calculating on any job site?" (Answer: Converting to a common format).

Day 1: Foundation Layout
The Hook
"Team, welcome to the job site. Before we build, we must inspect our materials. Some measurements are in decimals, some in fractions. We need a common language—our Conversion Code ."
Activity Facilitation: Foundation Layout Worksheet
Explain: "Phase 1 is about your toolkit. Check your Code! Phase 2 is about starting the build. Notice how we have both formats in one task. We must pick one!"
Think Aloud: "For Phase 4 (Site Inspection), use the Day 1 STAAR Strategy Script to guide students through the modeling and guided practice of Questions 10 and 11."

Day 2: Framing Fluency
Direct Instruction: Blueprint Success Guide
Facilitate: "Use the Day 2 Blueprint Success Guide as your lesson anchor. Walk students through the Multi-Step Protocol: Inspect, Convert, Build."
Model: "Perform the 'Guided Site Challenge' on the guide as a class. Show how the 15.8 feet must be the starting point, and we subtract the total used (\( 4\frac{1}{2} + 6\frac{3}{4} \))."
Independent Practice: Station Logbook
Direct: "Students will record their data from the Day 2 Construction Zone Stations Cards in their Logbooks. For Station 3 (Load Limits), prompt them: 'Are we subtracting from the 15-ton limit or adding to it?'"
Final Check: Safety Inspection
Modeling: "For the Safety Inspection (Page 2), emphasize the crane load problem ($2.75 + 4\frac{1}{2}$). Remind students to use the Strategy Tips from the Success Guide."

Day 3: Final Inspection
Guided Practice: Final Inspection Guide

GUIDED SITE CHALLENGE
An electrician has a wire that is 15.8 feet long. He uses \( 4\frac{1}{2} \) feet for the kitchen and \( 6\frac{3}{4} \) feet for the living room. How much wire is left?
Calculation Zone
Final Answer:
Phase 1: Conversion
Convert the fractions to decimals first. What is \( 4\frac{1}{2} \) and \( 6\frac{3}{4} \) as decimals?
Phase 2: Total Used
Add the two lengths that were used. Remember to line up the decimal points!
Phase 3: The Remainder
Subtract the total used from the original 15.8 feet.
Master Inspection Tips
1. Decimal Defense: Converting your final answer to a decimal is often the quickest way to verify your work against multiple-choice options.
2. Placeholder Power: Always use zeros to fill gaps in columns when subtracting. \( 15.80 - 6.75 \) is much safer than \( 15.8 - 6.75 \)!
3. Keyword Check: Does the problem ask for "total" (Add) or "left over" (Subtract)? Circle it before you start building.
4. Reasonableness: Does your answer make sense? If you start with ~16 and use ~11, your answer should be close to 5.

GUIDED MASTERY CHALLENGE
The glass siding team delivered 18.2 tons of glass in the morning and \( 15\frac{3}{5} \) tons in the afternoon. If the total goal for the week is 50 tons, how many more tons of glass are needed to pass inspection?
Step 1: The Morning/Afternoon Total
Convert \( 15\frac{3}{5} \) to a decimal:
Decimal: ________
Add deliveries (18.2 + delivery 2):
Total Used: ________
Step 2: Finding the Remainder
Subtract your Step 1 total from the 50 ton goal:
Final Inspection Answer:
The Zero Rule
When a whole number like 50 needs to meet a decimal, add .0 to keep columns aligned!
Flash Conversion
Remember: \( \frac{3}{5} \) is just double \( \frac{3}{10} \). Double 3 is 6, so it's 0.6!
Final Check
Does your answer make sense? If you delivered ~30 tons, you should need ~20 more.
