6th Grade Math Unit 8

Big Idea:

Determine side and angle relationships of triangle, and model and solve for area and volume of geometric figures.

Student Expectations:

Priority TEKS

6.8(A) [Supporting] extend previous knowledge of triangles and their properties to include the sum of angles of a triangle, the relationship between the lengths of sides and measures of angles in a triangle, and determining when three lengths form a triangle

6.8(D) [Readiness] determine solutions for problems involving the area of rectangles, parallelograms, trapezoids, and triangles and volume of right rectangular prisms where dimensions are positive rational numbers

Focus TEKS

6.8(B) [Supporting] model area formulas for parallelograms, trapezoids, and triangles by decomposing and rearranging parts of these shapes

6.8(C) [Supporting] write equations that represent problems related to the area of rectangles, parallelograms, trapezoids, and triangles and volume of right rectangular prisms where dimensions are positive rational numbers

Student Learning Targets:

• I will discover and apply the area formulas for rectangles, parallelograms, trapezoids and triangles.
• I will calculate the volume of a rectangular prism.
• I will write how I can use area and volume in a real-life situation

Essential Questions:

• What is the relationship between the sides of a triangle?
• What is the relationship between the angles in a triangle?
• What is the relationship between the sides and angles in a triangle?
• What does area and volume measure?
• How can you find the area of quadrilaterals and triangles?
• How can you find the volume of a rectangular prism?
