# 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]
