Think-Pair-Share Activity Plan: Decimal Adventures in Spain
May 29, 2025


To design an engaging Think-Pair-Share activity, I used the chat window on the “Create” page and entered the following sentence:
“I want to create a think-pair-share on the topic of multiplication and division involving decimals for grade 6. Use CBSE in India. Try to find an exciting Indian movie as a theme.”
After the form window appeared with the values pre-filled, I clicked generate and received this result:
Learning Objectives
Apply multiplication and division operations with decimals in real-world contexts
Convert between different currencies using decimal operations
Solve multi-step problems involving decimal calculations
Justify mathematical reasoning and communicate solution strategies effectively
Develop estimation skills to verify the reasonableness of answers
Think Phase Materials (15 minutes)
Problem Scenario: "Spanish Adventure Budget"
Student Handout
Spanish Adventure Budget Challenge
Three friends - Arjun, Imran, and Kabir - are planning a trip to Spain. They need your help to plan their budget!
Currency Information:
1 Euro (€) = ₹91.25 Indian Rupees
The friends have a combined budget of ₹375,000 for activities
Adventure Activities in Spain:
Scuba Diving: €85.50 per person
Skydiving: €299.99 per person
Running with the Bulls: €125.75 per person
Flamenco Dance Class: €45.50 per person
La Tomatina Festival: €75.25 per person
Wine Tour: €65.90 per person
Your Tasks:
Calculate the cost in euros for all three friends to participate in each activity.
Convert these costs to Indian Rupees.
If they want to do all six activities, what will be the total cost in rupees?
Will their budget of ₹375,000 be enough? If not, which activities should they skip to stay within budget?
If they have ₹50,000 left after activities, and want to divide it equally for shopping, how much can each friend spend in euros?
Show all your calculations and reasoning!
Teacher Guidance for Think Phase
Distribute the handout to students and provide individual thinking time.
Encourage students to organize their work clearly, showing all calculations.
Prompt students to use estimation to check their answers.
Circulate to observe student approaches and identify misconceptions.
Provide scaffolding questions for struggling students:
"How would you convert from euros to rupees?"
"What operation would you use to find the cost for three people?"
"How can you determine if the budget is sufficient?"
Pair Phase Materials (15 minutes)
Visibly Random Groups Method
Implementation:
Prepare playing cards with matching pairs (e.g., two Kings of Hearts, two 7 of Diamonds).
Shuffle and distribute one card to each student.
Instruct students to find their matching card partner.
Pair Discussion Guide
Partner Discussion Prompts
Compare your calculations for each activity cost. Did you get the same answers? If not, work together to find where the differences occurred.
Discuss your strategies for converting between currencies. Which method is more efficient?
Compare your recommendations for which activities to skip if the budget isn't sufficient. Explain your reasoning to your partner.
Check each other's work using estimation. For example, €300 is approximately ₹27,000, so three people would cost around ₹81,000.
Create a clear, organized solution that shows all your work and reasoning.

Teacher Guidance for Pair Phase
Circulate among pairs to listen to discussions and provide guidance.
Look for different solution strategies to highlight during the share phase.
Identify common errors or misconceptions to address.
Encourage pairs to check their work using estimation.
Prompt deeper thinking with questions like:
"How did you decide which activities to prioritize?"
"What would happen if the exchange rate changed?"
"Is there more than one correct answer for which activities to skip?"
Share Phase Materials (15 minutes)
Whole Class Discussion Structure
Select 3-4 pairs to present different aspects of their solutions:
Pair 1: Conversion method and calculations for activities
Pair 2: Budget analysis and decision-making process
Pair 3: Shopping money calculations
Pair 4: Alternative approaches or interesting insights
Presentation format: Each pair displays their completed solution template and explains their reasoning.
Class discussion prompts:
"What patterns did you notice in the calculations?"
"What was challenging about this problem?"
"How did you verify your answers were reasonable?"
"How is this math relevant to real-life travel planning?"
Solution Guide for Teacher Reference
Calculations:
Cost for all three friends per activity (in euros):
Scuba Diving: €85.50 × 3 = €256.50
Skydiving: €299.99 × 3 = €899.97
Running with Bulls: €125.75 × 3 = €377.25
Flamenco Class: €45.50 × 3 = €136.50
La Tomatina: €75.25 × 3 = €225.75
Wine Tour: €65.90 × 3 = €197.70
Converting to Indian Rupees (multiply by 91.25):
Scuba Diving: €256.50 × 91.25 = ₹23,405.63
Skydiving: €899.97 × 91.25 = ₹82,122.26
Running with Bulls: €377.25 × 91.25 = ₹34,423.56
Flamenco Class: €136.50 × 91.25 = ₹12,455.63
La Tomatina: €225.75 × 91.25 = ₹20,599.69
Wine Tour: €197.70 × 91.25 = ₹18,040.13
Total cost for all activities:
€2,093.67 or ₹191,047.00
Budget analysis:
Budget is sufficient (₹375,000 > ₹191,047)
They can do all activities and have ₹183,953 remaining
Shopping money calculation:
Remaining after activities: ₹50,000
Per person: ₹50,000 ÷ 3 = ₹16,666.67
In euros: ₹16,666.67 ÷ 91.25 = €182.65 per person

Common Misconceptions to Watch For
Decimal Point Errors: Students may misplace decimal points when multiplying or dividing, especially with currency conversion.
Intervention: Encourage estimation to check reasonableness of answers.
Operation Confusion: Students might multiply when they should divide or vice versa when converting currencies.
Intervention: Use the relationship "₹ = € × 91.25" and "€ = ₹ ÷ 91.25" as a reference.
Rounding Issues: Premature rounding may lead to significant errors in final calculations.
Intervention: Suggest rounding only at the final step.
Unit Tracking: Students may forget to label their answers with the correct currency symbol.
Intervention: Emphasize the importance of including units in all answers.

Extensions and Modifications
For Advanced Students
Variable Exchange Rate Challenge:
Investigate how the budget calculations would change if the exchange rate fluctuated by ±5% during their trip.
Calculate the minimum and maximum possible costs for all activities.
Optimization Problem:
If the friends want to maximize their experiences but can only do 4 activities, which combination would give them the most value? Create a rating system and justify your choices.
Multi-Country Extension:
Extend the trip to include Portugal, where the friends spend 3 days. Research activity costs in Portugal and create a comparative budget.
For Struggling Students
Simplified Calculations:
Round the costs to the nearest euro before calculating.
Focus on fewer activities initially (just 3 instead of 6).
Structured Worksheet:
Provide a step-by-step calculation template with more guidance.
Include partially completed examples.
Visual Supports:
Offer a visual flowchart showing the sequence of operations needed.
Provide a reference card with formulas for currency conversion.
Cultural Connections
Currency Exploration:
Examine the design of Euro notes and coins, discussing their cultural significance.
Compare with Indian Rupee designs and symbols.
Festival Research:
Have students research the actual La Tomatina festival and Running with the Bulls events to understand their cultural significance in Spain.
