Measuring the Trail: Unit Conversions for Wildlife Habitat Restoration

Shared by A STEM Educator

4th GradeBTC Vertical Whiteboard FramingCCSS.4.MD.A.1 / CCSS.4.MD.A.250 min
Learning Objective

Students will convert larger units to smaller units within the customary and metric systems using multiplication, and solve multi-step measurement word problems involving distance, mass, and liquid volume.

Lesson Overview

Students work in random groups of 3 at vertical non-permanent surfaces (VNPS) to discover and apply unit conversion patterns — starting from reading a conversion table and multiplying whole numbers, then building toward multi-step measurement word problems involving distance, mass, and volume in a wildlife habitat restoration context.

Materials

  • Vertical whiteboards or large chart paper taped to walls
  • Dry-erase markers (one per group member)
  • Erasers or socks
  • Random grouping cards or sticks
  • Printed conversion reference table (one per group, posted at board)
  • Student note sheets (Four-Quadrant Consolidation Notes, one per student)

Scaffolded Task Progression

1Task 1
The trail crew measures a log bridge as feet long. They need to report the length in inches for the supply order.

Use the conversion table at your board.

1. How many inches are in foot?
2. How many inches are in feet?
3. Write a multiplication equation that shows your thinking.
2Task 2
The restoration team needs feet of rope to tie down erosion netting along the trail edge. The hardware store sells rope by the inch.

1. How many inches of rope does the team need?
2. Write a multiplication equation.
