Mapping Fractions: Designing a Scaled City Map

Grade 5Math5 days

In the 'Mapping Fractions: Designing a Scaled City Map' project, fifth-grade students delve into math by using the concept of dividing fractions to create accurately scaled city maps. Students begin as 'Fraction Detectives' solving a mystery to engage critical thinking, then progress to designing their own maps on grid paper by applying their understanding of fractions and scaling. This immersive project aligns with Common Core standards by teaching students to apply fraction division, plot points on a coordinate plane, and understand measurements through line plotting, resulting in a student-created fractional grid map. Throughout, students reflect on their learning and develop both problem-solving and mathematical skills.

Common Core Standards

5.NF.B.7

Primary

Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions.Reason: The project focuses on dividing fractions to scale and map different areas of a city.

5.G.A.2

Secondary

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.Reason: Creating and interpreting a city map involves graphing points and understanding their real-world context.

5.MD.B.2

Supporting

Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots.Reason: Designing a map requires understanding measurements and can involve line plotting to represent fractional parts of a map.

Entry Events

Events that will be used to introduce the project to students

Fraction Detective: City Edition

Begin with a mystery scenario where the city is missing some pieces of its map. Students become 'Fraction Detectives' tasked to solve the mystery by calculating and placing missing map segments using fractions. This engaging scenario encourages critical thinking and problem-solving while providing a directly relevant context for learning.
