CCSS-Aligned Lesson on Using Multiplication, Division, and Other Operations in Real-World Applications!
Students will apply their multiplication and division skills in planning, plotting, planting and harvesting a garden, and then work with all four operations to determine pricing and profit for selling their produce at market.
This PBL unit for 3rd grade math will give your students am interesting, engaging, and collaborative way to practice the addition, subtraction, multiplication, and division skills they've learned while applying them to a real-world application. Using critical-thinking and problem-solving skills backed with data derived from real-world math, they will work individually and together to plan, plot, plant, harvest and sell the produce from a garden.

OVERVIEW:
This project-based learning lesson is designed to support and reinforce the concepts in a Grade 3 math unit on using multiplication and division, along with addition and subtraction, to solve real-world math problems. It is built around 5 inquiry-based milestones that incorporate cross-curricular hands-on projects, formative and summative assessments, independent and group activities, and extensions.
STUDENT/GROUP OUTPUT:
In the course of this project-based learning unit, students will:
Multiply and divide with groups and arrays;
Plan and plot a garden using multiplication, measurement, and estimation;
Use multiplication, division, and other operations to determine how to tend and harvest the garden;
Use addition, subtraction, multiplication, and division to determine quantities and profit of produce sold at market.
SUGGESTED SUBJECT PREREQUISITES:
Students should have background knowledge of multiplying, dividing, adding, subtracting, and measurement as part of this project, and instructional materials for providing refreshers and instruction are included in the Teacher Pack.
SEQUENCE AND PACING:
This project-based unit is divided into 5 milestones. The minimum suggested duration for completing this project-based unit is 5 class periods. However, the unit is completely flexible and can be lengthened or shortened as necessary or desired, based on available class time and interest level.
