 Sections Topics P.1-P.2 Real Number System, Intervals, Absolute Value Distance. Students examine the structure of the whole, integer, rational , and real number systems. They order integer, mixed numbers, rational numbers (including fractions, decimals, and percents) and real numbers. They describe the relationships between algorithms for addition, subtraction, multiplication, and division. They understand the properties of number systems and their relationship to the algorithms. [e.g. 1 is the multiplicative identity; 27 + 34 = 2 × 10 + 3 + 3× 10 + 4 = (2 + 3) × 10 + (7 + 4)]. They perform operations with positive, negative, and fractional exponents, as they apply to whole numbers and fractions. They show an understanding of the order of operations. They estimate and measure length. P.3-P.4 Integer and Rational Exponents, Polynomials, scientific notation. Students revise their understanding of base ten place value, including representation of numbers in exponential and scientific notation. They describe the relationships between algorithms for addition, subtraction, multiplication, and division. They perform operations with positive, negative, and fractional exponents, as they apply to whole numbers and fractions. They round numbers and estimate the result of calculations, and place numbers accurately on a number line. P.5-P.6 Factoring and Rational Expressions. Students review number theory concepts including prime numbers, greatest common factors. They describe the relationships between algorithms for addition, subtraction, multiplication, and division. They perform operations with positive, negative, and fractional exponents, as they apply to whole numbers and fractions. They use proportional reasoning. Students have a basic understanding of the multiplication, division and factoring of polynomials. Students estimate and measure area.
