Inquiry Framework

Question Framework

Driving Question

The overarching question that guides the entire project.How can we, as food truck owners, use math to ensure every customer gets a fair share, every recipe is perfect, and our truck arrives on time for the Global Food Truck Festival?

Essential Questions

Supporting questions that break down major concepts.
  • How can we divide our signature dishes into equal parts (fractions) so every customer gets a fair share?
  • How do we use measurement tools for mass and volume to ensure our secret recipes taste the same every time?
  • How can we create a precise travel and cooking schedule so we arrive at our stops and serve our food exactly on time?
  • Why is it important to choose the correct unit of measurement (like grams vs. kilograms or milliliters vs. liters) when stocking our food truck supplies?
  • How do we use math to compare the amount of ingredients we have versus the amount we need for a festival crowd?

Standards & Learning Goals

Learning Goals

By the end of this project, students will be able to:
  • Students will partition whole food items into equal parts and represent these parts as unit fractions to ensure fair customer portions.
  • Students will calculate elapsed time to create a precise schedule for travel, food preparation, and service during the festival.
  • Students will measure and estimate the mass of solid ingredients and the volume of liquid ingredients using metric units (grams, kilograms, liters).
  • Students will solve one-step word problems involving mass and volume to manage food truck inventory and recipe adjustments.
  • Students will evaluate and select the most appropriate measurement tools and units for various food truck supplies.

Common Core State Standards (Math)

CCSS.MATH.CONTENT.3.MD.A.1
Primary
Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.Reason: This standard is central to the project's goal of creating a travel and cooking schedule for the festival.
CCSS.MATH.CONTENT.3.MD.A.2
Primary
Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units.Reason: Students must use mass and volume to follow recipes accurately and manage their food truck inventory.
CCSS.MATH.CONTENT.3.NF.A.1
Primary
Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.Reason: Students will use this to divide signature dishes into fair portions for customers at the festival.
CCSS.MATH.CONTENT.3.G.A.2
Supporting
Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.Reason: This supports the visual partitioning of food items (like pizza or trays of food) into fractional pieces.

Entry Events

Events that will be used to introduce the project to students

The 'Fair Share' Fraction Court

The class 'attends' a mock 'Foodie Court' where customers are complaining about getting smaller slices of pizza or less juice than their friends. Students are challenged to invent a 'Perfect Portion' system using fractions to ensure every customer gets an exactly equal share of the truck's signature dishes.

The 'Frantic Food Trucker' SOS

Students receive a 'distress call' video from a famous chef whose digital dashboard just crashed right before the Global Festival. They must step in as consultants to reconstruct the truck's complex route schedule and fix recipes where the measurements have been scrambled into confusing fractions.

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

The Fair Share Blueprint

Before the food truck can open, students must design their 'Signature Dish' and prove it can be divided fairly among customers. Students will choose a shape (circle for pizza, rectangle for a tray of sliders) and partition it into equal fractional parts to ensure every customer gets the exact same amount.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Choose your signature food item (e.g., a square pan of lasagna, a circular pizza, or a rectangular tray of brownies).
2. Decide how many people you need to serve (the denominator) and partition your food item into that many equal-sized pieces.
3. Shade one portion and label it as a unit fraction (1/b). Then, shade multiple portions and label it (a/b).
4. Write a 'Fair Share Guarantee' explaining that because the areas are equal, the portions are fair.

Final Product

What students will submit as the final product of the activityA 'Portion Poster' displaying the signature dish partitioned into equal parts, with each section labeled with its unit fraction and a written explanation of how they ensured the parts were equal.

Alignment

How this activity aligns with the learning objectives & standardsCCSS.MATH.CONTENT.3.NF.A.1 (Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts); CCSS.MATH.CONTENT.3.G.A.2 (Partition shapes into parts with equal areas).
Activity 2

The Secret Recipe Scientist

Now that the portions are set, students must determine the weight of their ingredients. They will practice using scales to measure the mass of dry ingredients (like flour, sugar, or spices) to ensure their secret recipe is perfect every time. They will also learn to choose between grams for small amounts and kilograms for bulk supplies.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Identify five dry ingredients needed for your signature dish.
2. Use a balance or digital scale to measure the mass of a sample of each ingredient.
3. Record the mass in grams. If the item is very heavy (like a sack of flour), estimate and record it in kilograms.
4. Compare two ingredients: write a comparison sentence using <, >, or = based on their masses.

Final Product

What students will submit as the final product of the activityA 'Mass Master Sheet' that lists 5 key ingredients, their measured mass in grams or kilograms, and a justification for why they chose that specific unit of measurement.

Alignment

How this activity aligns with the learning objectives & standardsCCSS.MATH.CONTENT.3.MD.A.2 (Measure and estimate liquid volumes and masses of objects using standard units of grams, kilograms, and liters).
Activity 3

The Quenching Calculator

Every food truck needs a signature drink! Students will measure the volume of liquid ingredients to create a 'Festival Punch.' They will use liters and milliliters to mix their concoction and solve problems to ensure they have enough volume to fill a certain number of cups.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Use graduated cylinders or measuring beakers to measure different liquids (water, juice, etc.) in milliliters.
2. Add the volumes together to find the total volume of your 'Signature Drink' recipe.
3. Solve the 'Refill Challenge': If a customer drinks 200ml and the pitcher holds 1 liter (1,000ml), how much is left?
4. Determine the best tool to measure a large vat of punch versus a single serving cup.

Final Product

What students will submit as the final product of the activityA 'Volume Recipe Card' showing the total milliliters/liters of the drink and a calculation showing how many liters of liquid are needed to serve the whole class.

Alignment

How this activity aligns with the learning objectives & standardsCCSS.MATH.CONTENT.3.MD.A.2 (Measure and solve problems with liquid volume; Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes).
Activity 4

The Clock-Wise Commute

Timing is everything in a food truck! Students will create a 'Festival Route & Prep Schedule.' They must calculate the elapsed time it takes to drive from the kitchen to the festival grounds and how much time they need for food preparation to ensure they are ready for the 'Grand Opening' at a specific time.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Set a 'Grand Opening' time (e.g., 12:30 PM).
2. Determine how long each task takes (e.g., Driving = 45 mins, Chopping = 20 mins, Grilling = 35 mins).
3. Work backward from the 'Grand Opening' time using a number line to find the 'Start Time' for your day.
4. Solve 'Traffic Jam' word problems: 'If a traffic jam adds 15 minutes to your drive, what is your new arrival time?'

Final Product

What students will submit as the final product of the activityA 'Trucker’s Timeline'—a visual number line showing the start times and end times for travel, setup, and cooking, with elapsed time intervals clearly marked.

Alignment

How this activity aligns with the learning objectives & standardsCCSS.MATH.CONTENT.3.MD.A.1 (Tell and write time to the nearest minute; measure time intervals; solve word problems involving addition and subtraction of time intervals).
Activity 5

The Grand Opening Manual

To prepare for the final festival, students compile all their data into a 'Food Truck Operations Manual.' This manual serves as their final pitch, showing that they have mastered fractions for portions, mass/volume for recipes, and time management for logistics.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Review all previous activities and check for mathematical accuracy.
2. Create a 'Menu' page that lists the price for a 1/4 slice versus a 1/2 slice of your dish.
3. Include a 'Logistics' page with your time-stamped schedule and your ingredient inventory (mass/volume).
4. Prepare a 1-minute pitch explaining why your truck is the most mathematically precise truck at the festival.

Final Product

What students will submit as the final product of the activityThe 'Global Food Truck Operations Manual'—a multi-page portfolio featuring the partitioned dish, the mass/volume recipe, and the timed schedule, ready to be presented to 'Festival Organizers.'
