Sept15-19

Standard 1: Number and Computation – The student uses numerical and computational concepts and procedures in a variety of situations.

Benchmark 1: Number Sense – The student demonstrates number sense for rational numbers, the irrational number pi, and simple algebraic expressions in one variable in a variety of situations.

Knowledge Indicator 1. The student knows, explains, and uses equivalent representations for rational numbers and simple algebraic expressions including integers, fractions, decimals, percents, and ratios; integer bases with whole number exponents; positive rational numbers written in scientific notation with positive integer exponents; time; and money (2.4.K1a- c) ($), e.g., 253,000 is equivalent to 2.53 x 105 or x + 5x is equivalent to 6x. 2. The student compares and orders rational numbers and the irrational number pi (2.4.K1a) ($). 3. explains the relative magnitude between rational numbers and between rational numbers and the irrational number pi (2.4.K1a).

Application Indicator - 1. The student generates and/or solves real-world problems using (2.4.A1a) ($): a. ▲equivalent representations of rational numbers and simple algebraic expressions, e.g., you are in the mountains. Wilson Mountain has an altitude of 5.28 x 103 feet. Rush Mountain is 4,300 feet tall. How much higher is Wilson Mountain than Rush Mountain?

b. fraction and decimal approximations of the irrational number pi, e.g., Mary measured the distance around her 48-inch diameter circular table to be 150 inches. Using this information, approximate pi as a fraction and as a decimal.
