CTE Concept(s): Finding the diagonal of a building to insure that it’s square
Math Concepts: Pythagorean Theorem, converting feet-inch-fraction of inch measurements to decimals, converting decimals back to
feet-inch-fraction of inch measurements.
Lesson Objective: This is the second in a series of lessons to be a

of converting the measurements between fractions and decimals. T
lesson objective will be to take measurements in feet-inches
convert them to decimals.
Supplies Needed: tape measure, basic calculator that d
