7th Grade Math Unit 8

Big Idea:

Calculate the volume of three dimensional objects.

Student Expectations:

Priority TEKS

7.9(A) [Readiness] Solve problems involving the volume of rectangular prisms, triangular prisms, rectangular pyramids, and triangular pyramids.

Focus TEKS

7.8(A) [Not Tested] model the relationship between the volume of a rectangular prism and a rectangular pyramid having both congruent bases and heights and connect that relationship to the formulas

7.8(B) [Not Tested] explain verbally and symbolically the relationship between the volume of a triangular prism and a triangular pyramid having both congruent bases and heights and connect that relationship to the formulas

7.9(D) [Supporting] solve problems involving the lateral and total surface area of a rectangular prism, rectangular pyramid, triangular prism, and triangular pyramid by determining the area of the shapes net.

Ongoing TEKS

7.3(A) [Supporting] Add, subtract, multiply, and divide rational numbers fluently.

7.11(C) [Supporting] write and solve equations using geometry concepts, including the sum of the angles in a triangle, and angle relationships.

Student Learning Targets:

• I will calculate the volume of prisms and pyramids.
• I will use nets to determine lateral and total surface area of prisms and pyramids.

Essential Questions:

• How can we use algebra to determine the volume and surface area of three dimensional objects?
