7th Grade Math Unit 7

Big Idea:

Use algebra to determine real world measurements.

Student Expectations:

Priority TEKS

7.9(B) [Readiness] Determine the circumference and area of circles

7.9(C) [Readiness] Determine the area of composite figures containing combinations of rectangles, squares, parallelograms, trapezoids, triangles, semicircles, and quarter circles

Focus TEKS

7.5(B) [Supporting] describe Pi as the ratio of the circumference of a circle to its diameter

7.8(C) [Not Tested] use models to determine the approximate formulas for the circumference and area of a circle and connect the models to the actual formulas

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

Ongoing TEKS

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

7.5(A) [Supporting] generalize the critical attributes of similarity, including ratios within and between similar shapes

Student Learning Targets:

• I will determine the area of various geometric shapes using formulas.
• I will describe Pi as a ratio of the circumference of a circle to its diameter.
• I will determine the area and circumference of circles.
• I will calculate the total area of composite figures.

Essential Questions:

• How do measurements help describe real world object?
