Technology Integrator Interview, WAWM Volume of a Rectangular Prism Academic Standard(s): CC.8.G9, CC.K-­‐12MP1, CC.K-­‐12MP5 Instructional Objective(s): Students will be able to: • Explore resources and find the formula for volume of a rectangular prism • Measure a fish tank and find the volume • Convert the volume from cubic inches to gallons Questions: • What is the formula for volume? • How do we use the formula to estimate gallons? • If we are given the volume of a 3-­‐Dimensional figure, are we able to find the value of one missing side? • How is understanding volume applicable to the real world? When will this be a valuable school? Key Vocabulary: Volume, length, base, height, capacity Materials: • Textbook: Prentice Hall Mathematics—Pre-­‐Algebra • SMARTBoard file (notes, examples, practice problems) • Volume Worksheet • iPads • Video Clip from Animal Planet: http://animal.discovery.com/tv-­‐shows/tanked/videos/reveal-­‐spencers-­‐tank.htm Evaluation of Learner Performance (assessment): • Classroom discussion, practice problems, completion of group work: articulate/demonstrate knowledge of finding volume of a rectangular prism and completion of Calculating Volume Worksheet Differentiation: • Enrichment IXL activity • Support for Students with IEPs: visuals, printed notes, preferential seating, reduced number of problems, supported work time, re-­‐teaching with partners, the use of a calculator Volume of a Rectangular Prism INSTRUCTIONAL EVENTS: Introduction • Student Research -­‐ Students will research a series of three questions using their iPad, and write down their findings in their notes Ø What is the definition of volume? Ø What is the formula for volume of a rectangular prism? Ø How is volume different than area? Classroom Discussion -­‐ Discuss the students’ finding, if all students have a different definition of volume, find similar words and create a classroom definition -­‐ Agree on a formula for finding volume of a rectangular prism, have students highlight the formula in their notes •
Problem Solving • Questions: Show students the fish tank. How many of you have a fish tank at home? When you (or your parents) bought the fish tank, the box said that it could hold a certain number of gallons. How do ‘they’ get that number? What size fish tank do you think this is? What number would be on the box? -­‐ Students will discuss the questions at their tables first, and hypothesize how many gallons of water will fit into the fish tank • Group Work -­‐ Find the measurements of the fish tank (length, height, base) -­‐ Find the volume of the fish tank using the formula -­‐ Students will research the conversion from cubic inches to gallons, and predict whether their estimation of gallons will fit into the tank. • Closure -­‐ How many gallons of water will fit? How do we know that this is accurate? -­‐ Pour 5 gallons of water into the fish tank to make sure that it fits Solving Equations • Guided Practice: -­‐ Complete guided practice problems as a class in notebook (I Do, We Do, You Do) -­‐ Introduce problems where students are given the volume, and need to find a missing length. •
Homework: -­‐ Volume Worksheet, 1 – 6 -­‐ IXL Q.27 -­‐ Enrichment: IXL Q.28 •
Closure: Watch video clip from Animal Planet’s TV show ‘Tanked’. Have students write an exit slip answering the following questions: -­‐ What shape is the fish tank that they created? -­‐ What figure is it supposed to represent? -­‐ Can we use the formula that we learned today to find the volume of the fish tank?
