IN.6.3. Algebra and Functions
Students write verbal expressions and sentences as algebraic expressions and equations. They evaluate algebraic expressions, solve simple linear equations, and graph and interpret their results. They investigate geometric relationships and describe them algebraically.
6.3.2 Write and use formulas with up to three variables to solve problems.
6.3.5 Use variables in expressions describing geometric quantities.
Students deepen their understanding of the measurement of plane and solid shapes and use this understanding to solve problems. They calculate with temperature and money, and choose appropriate units of measure in other areas.
6.5.4 Understand the concept of the constant pi as the ratio of the circumference to the diameter of a circle. Develop and use the formulas for the circumference and area of a circle.
6.5.5 Know common estimates of pi (3.14, 22/7) and use these values to estimate and calculate the circumference and the area of circles. Compare with actual measurements.
