# Using Resources Effectively

ACP Lesson Plan

Overview / Description:

In this math lesson, students will be using math skills to determine the best layout of industrial parts to be cut from a sheet of metal. Students will then calculate both the cost of the materials used and the percentage and cost of waste remaining after cutting out the industrial parts.

Learning goals/objectives:

After completing this activity, students should be able to . . .

• create a layout of industrial parts which makes the best use of resources
• calculate the cost of materials used
• calculate the cost and percentage of waste remaining after cutting out industrial parts

Content Standards:

Common Core Standards for Math

CCSS.MATH.CONTENT.6.G.A.1

Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.

Standard E: Students will demonstrate effective decision-making, problem-solving, and goal-setting skills.

Materials:

• 20 x 24 Graph Paper

• Scissors

Learning Activities:

Assessment:

Teacher will circulate during work periods to observe progress.

Student groups will complete Exit ticket at the end of the period as a formative assessment.

Wrap-Up:

Have students complete the exit ticket. Do a whip-around of groups to see who had the smallest area of waste.

Extension Activity (for intervention or enrichment):

• Struggling students could work in a small group rather than in pairs.
• Think-pair-share: Student pairs could find another pair and collaborate before cutting takes place in Step 3.
• Student groups could take a picture of their graph paper before cutting out their shapes to share on Day 2 in a discussion of how each group determined how to place their shapes and reduce waste.
• Teacher could invite a CNC programmer in to discuss the importance of reducing waste and using resources effectively.
• Summative assessment could include students completing a similar activity individually after feedback from exit tickets.
