6. UNIT 5 Standards for Mathematical Practice, Strategies and Misconceptions Specific Standards for Mathematical Practice Below are the relevant Standards for Mathematical Practice for the task: Volume and Cubes. STANDARDS FOR MATHEMATICAL PRACTICE 1.Make sense of problems and persevere in solving them. Students will solve problems by finding the volume of rectangular prisms with fractional edges. 2. Reason abstractly and quantitatively Students will use their understanding of the volume to find the number of cubes that will fit inside a rectangular prism. Students will be able to see and justify the reasoning packing a rectangular prism to find volume. 6. Attend to precision. Students will use appropriate measurement units (square units and cubic units) and correct terminology to justify reasonable solutions. 7. Look for and make use of structure. Students will understand the relationship between the structure of a three-dimensional shape and its volume formula. 8. Look for and express regularity in repeated reasoning. Students use properties of figures and properties of operations to connect formulas to volume.

7. UNIT 5 Standards for Mathematical Practice, Strategies and Misconceptions

8. UNIT 5 Standards for Mathematical Practice, Strategies and Misconceptions MISCONCEPTIONS 1. Students may believe the orientation of the figure changes the type of figure. They struggle with recognizing common figures in different orientation. For example students may think that “square” rotated 45 degrees is no longer a square and instead is called a “diamond.” This impacts students’ ability to decompose composite figures and to appropriately apply formulas for area. Providing multiple orientations of objects within classroom examples and work is essential for students to overcome this misconception. 2. Students may have trouble identifying the height of triangles and parallelograms. They confuse the height with always being a side length. Height is the altitude and must perpendicular to the base (form a right angle). 3. The height of a triangle can be one of the sides of the right angle in a right triangle. The height is an interior segment in an acute triangle, and it is an exterior segment (the base needs to be extended) in an obtuse triangle. See the screen shots below from the GeoGebra web site for examples of each of these types of triangles.

9. Unit 5 Changes TASKS Kept the Same:  Who put the Tang in Tangram?  What's My Area?  King Arthur's New Table  How many Ways?

10. Unit 5 Changes TASKS Changed:  Packing Our Goods  Boxing Bracelets  Culminating Task

11. Unit 5 Changes TASKS ADDED:  Rectangle Wrap-around  Finding Surface Area  Volume and Cubes

12. Unit 5 Changes Packing Our Goods

13. Unit 5 Changes Finding Surface Area

14. Unit 5 Changes Volume and Cubes

15. Unit 5 Changes 2 short cycle tasks  Candle Box  Smoothie Box

16. Unit 5 Changes 1 FAL  Designing Candy Cartons

17. Vocabulary Changes Added vocabulary  Composing  Decomposing  Dimension  Trapezoid – using the inclusive definition:  A quadrilateral with AT LEAST one pair of parallel sides http://www.illustrativemathematics.org/illustrations/1505

18. Points for Teachers What is a “special quadrilateral”? Students need to find the area of trapezoids and rhombi by decomposing figures, not by formulas Use the formula sheet for the CRCT provided on the GaDOE website http://www.gadoe.org/Curriculum-Instruction-and- Assessment/Assessment/Documents/CRCT%20Mathematics%2 0Formula%20Sheet%20Revised2013.pdf http://www.gadoe.org/Curriculum-Instruction-and- Assessment/Assessment/Documents/CRCT%20Mathematics%2 0Formula%20Sheet%20Revised2013.pdf Surface area is found by breaking down the shapes, NOT by using the formulas

30. Leo’s recipe for banana bread won’t fit in his favorite pan. The batter fills the 8.5 inch by 11 inch by 1.75 inch pan to the very top, but when it bakes it spills over the side. He has another pan that is 9 inches by 9 inches by 3 inches, and from past experience he thinks he needs about an inch between the top of the batter and the rim of the pan. Should he use this pan?
