Lesson plan based on Amenemhet
Calculate the weight of a limestone block in both metric and U.S. customary measurements.
Skills and Focus: Calculation, Problem Solving
Subject Area: Mathematics
Thematic Connection: Counting and Calculating
Grade Level: Secondary School
Time Needed: 30 minutes
Objectives
• Make inferences by applying measurable ratios to known data.
• Convert from U.S. customary to metric measurement.
Instructional Materials Needed
Activity
Step 1: Explain the following known properties of the limestone block:
• length: 30.48 cm
• width: unknown
• thickness: 6.3 cm
Step 2: Using the printout of the wall fragment, encourage students to determine the width of the block.
Step 3: Assuming that the density of the limestone is 1,400kg/m3, have students determine the weight of the block.
Step 4: Finally, have students convert all of these measurements to U.S. customary measurements.
Goals
This activity meets Illinois State Goal 8: Use algebraic and analytical methods to identify and describe patterns and relationships in data, solve problems, and predict results.
