Measure Up with Common Core: Hands-on Perimeter, Area, and
Volume
Elizabeth Berman Appelbaum
Slide 2
Area and Perimeter 1 Inch Grid, No Formulas
A = sq in P = in
Slide 3
Area and Perimeter with Fractions, 1 Inch Grid
A = sq in P = in
Slide 4
Area and Perimeter with Fractions, 1 Inch Grid, Con.
Do Page 1 of Worksheet
Slide 5
Area and Perimeter with Formulas
• Measure the sides first.
Slide 6
Area with Formula, Con.Sides are w and d inches
Slide 7
Perimeter with FormulaSides are w and d inches
Slide 8
Mixed Numbers are Better than Improper Fractions
• Do not use improper fractions when–multiplying a mixed number and a whole
number– Adding a set of mixed numbers– Adding a set of mixed numbers and
whole numbers
• Reasons: efficiency and usefulness.• Do page 2 of worksheet.• I will pass out rulers.
Slide 9
Volume of a Rectangular Prism
• Students must handle actual cubes• First, find volume and lateral (side)
area without formulas• Then use formulas. • Furniture and appliances are
commonly described with width, depth, and height. So I use w, d, and h. The formula for volume is
Slide 10
SurfaceArea of a Prism
• This formula applies to right prisms (top and bottom aligned) and right cylinders, with height h.
• First find the perimeter P of the base.• Then use this formula for lateral area.
• Fold paper to motivate the formula.• Best way to measure walls for paint or wallpaper.• To find total surface area, find lateral area first. Then find top
area, double it, and add that number to lateral area.• Do page 3 of worksheet.
Slide 11
Playacting
• Work in groups of 2 or 3.• Each group makes up a show about
area, perimeter, volume, lateral area, or total surface area.
• Give your show to another group.• Then watch their show.
