Rules for manipulatives: We will be using centimeter cubes to make cubes and rectangular prisms and making nets of prisms. 1.Use these cubes and other items as tools to help you understand surface area and volume. Make sure you return the same number of cubes you were given. Clean up all materials. 4. Hands off when told to listen.
Build a 2 x 2 x 2 cube and find the surface area. Draw and record your findings in your notes. Surface Area ___________
Build a cube whose length, width and height is 3 x 3 x 3 cm. Find the surface area of the cube. Draw and record your findings. 3 cm 3 cm 3 cm
Build a cube that is 4 X 4 X 4cm in length, Draw and record your findings in your notes. 4 cm 4 cm 4 cm
Why is area measured in square units? Why is volume measures in cubic units?
Today’s task:(Record your work in a table.) Make one net of a rectangular prism (make sure it folds into a rectangular prism) 2. Measure in centimeters the length, width and height. RECORD MEASUREMENT! On your net label all measurements. Calculate and Record the Surface Area (Total area of each rectangle) 5. Measure and record information for 7 other rectangular prisms.
Make the table below on your paper. Measure in centimeters
