Students design a realistic pizza shop on a coordinate grid and use positive and negative numbers, ratios, absolute value, and decimal operations to make accurate decisions about layout, spacing, sizing, and pricing. The work is broken into clear daily chunks with extra white space, teacher check-ins, and support from the special education math teacher so every student can build and revise a strong plan. Across the week, students reflect on their accuracy, track their progress, and improve an early draft into a final map and exhibit that they can share with classmates and teachers at the pizza party showcase.
Learning goals
Students will accurately build and revise a pizza shop coordinate plan by plotting and labeling points in all four quadrants, using positive and negative numbers, absolute value, and ordered pairs to describe location and distance. They will solve realistic planning problems with ratios, fractions, and decimal operations to determine pricing, size, spacing, and scale, showing their work in chunked steps with extra white space for drafts and corrections. Students will strengthen communication, collaboration, and self-direction by using daily reflection notes, progress trackers, teacher check-ins, and support from the special education math teacher to improve one section of their work over time. They will share a final exhibit board and labeled map that explain their math choices and show clear growth from an early draft to a polished final version.
Standards
[Massachusetts] 6.NS.B.3 - Fluently add, subtract, multiply, and divide multi-digit decimals using the standard algorithm for each operation.
[Massachusetts] 6.RP.A.1 - Understand the concept of a ratio including the distinctions between part:part and part:whole and the value of a ratio; part/part and part/whole. Use ratio language to describe a ratio relationship between two quantities.
[Massachusetts] 6.RP.A.3 - Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
[Massachusetts] 6.NS.C.5 - Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, and positive/negative electric charge). Use positive and negative numbers (whole numbers, fractions, and decimals) to represent quantities in real-world contexts, explaining the meaning of zero in each situation.
[Massachusetts] 6.NS.C.8 - Solve real-world and mathematical problems by graphing points in all four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate.
[Massachusetts] 6.NS.C.6 - Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.
[Massachusetts] 6.NS.C.7 - Understand ordering and absolute value of rational numbers.
[Massachusetts] 5.NF.B.6 - Solve real-world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem.
[Massachusetts] 5.NF.B.4 - Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction.
[Massachusetts] 5.NF.B.7 - Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.
[Massachusetts] 5.G.A.1 - Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the zero on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g., x-axis and x-coordinate, y-axis and y-coordinate).
[Massachusetts] 5.G.A.2 - Represent real-world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation.
[Massachusetts] 5.NBT.B.7 - Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction and between multiplication and division; relate the strategy to a written method and explain the reasoning used.
[Massachusetts] 5.NBT.B.5 - Fluently multiply multi-digit whole numbers. (Include two-digit × four-digit numbers and, three-digit × three-digit numbers) using the standard algorithm.
Competencies
Effective Communication - Students practice listening to understand, communicating with empathy, and share their learning through exhibiting, presenting and reflecting on their work.
Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.
Collaboration - Students co-design projects with peers, exercise shared-decision making, strengthen relational agency, resolve conflict, and assume leadership roles.
Self Directed Learning - Students use teacher and peer feedback and self-reflection to monitor and direct their own learning while building self knowledge both in and out of the classroom.
Academic Mindset - Students establish a sense of place, identity, and belonging to increase self-efficacy while engaging in critical reflection and action.
Products
Students will create chunked draft sections of a pizza shop coordinate plan throughout the week, with labeled points, decimal measurements, ratio notes, distance markings, and extra white space for showing work and revisions. They will also complete brief reflection notes and a daily progress tracker after each chunk, plus either a teacher-conferenced checklist record or a before-and-after revision page that shows how one early draft improved. By the end, students will produce a labeled pizza shop coordinate map and contribute to an annotated class exhibit board featuring the finished grid, sample decimal calculations, and explanation cards. The project will be shared at a small-group pizza party exhibition with classmates and about three teachers.
Launch
Open with a Pizza Party Grid Preview by taping a giant coordinate plane on the floor and giving students simple “shop setup” cards such as “place the register at (-2, 3)” or “plot a table 4.5 units from the origin.” In teams, students physically walk the coordinates, label pizza shop features, and solve quick decimal price and ratio prompts such as comparing slice deals or ingredient amounts. Pause for a whole-group notice-and-wonder about how positive and negative numbers, distance, and pricing help organize a real pizza shop. End with students sketching a first draft of the layout in chunked sections with extra white space, then marking one part they feel confident about and one part they want help checking.
Exhibition
Host a small “Pizza Party Map Gallery” where students present their labeled coordinate maps and the annotated class exhibit board to their small group class and about three teachers. Each student explains one plotted location, one decimal pricing or measurement calculation, and one revision shown in their before-and-after comparison page. Display reflection notes, distance markings, and sample ratio thinking beside the final grid so visitors can see both the math process and the finished plan. Include a short feedback walk where guests leave one comment about accuracy, clarity, or improvement for each student or pair.
