Math (TAG): Developing Circle Relationships and Solving Problems

Suggested Time Frame: 10 Instructional Days

        

Focus TEKS
  • 7.9B determine the circumference and area of circles (R)  e
    • 7.5B describe π as the ratio of the circumference of a circle to its diameter (S)
    • 7.8C use models to determine the approximate formulas for the circumference and area of a circle and connect the models to the actual formulas
Computational Fluency TEKS

Calculating Equivalences

  • 6.5C use equivalent fractions, decimals, and percents to show equal parts of the same whole (S)

Measuring and Calculating Perimeter, Area, and Volume

  • 5.4H represent and solve problems related to perimeter and/or area and related to volume. – R RC3
  • 6.8D 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 (R)
Spiral Review TEKS

Independent and Dependent Quantities

  • 6.6A identify independent and dependent quantities from tables and graphs (S)

Triangle Types and Measuring Angles

  • 4.6C apply knowledge of right angles to identify acute, right, and obtuse triangles; and – S RC3
  • 4.7C determine the approximate measures of angles in degrees to the nearest whole number using a protractor; – R RC3
    • 4.7E determine the measure of an unknown angle formed by two non-overlapping adjacent angles given one or both angle measures. – S RC3 [including complementary and supplementary angles]
