Whole Number Comparison** - Compare and order integers and positive rational numbers. (1A) **T B Rational Number Comparison** - Compare and order integers and positive rational numbers. (1A) **T B Operations: Addition and Subtraction** - Use addition, subtraction, multiplication and division to solve problems involving fractions and decimals. (2B) **T B Squares and Irrational Numbers** - Represent squares and square roots using geometric models. (1C) **T B Order of Operations -** Use models, such as concrete objects, pictorial models, and number lines, to add, subtract, multiply, and divide integers and connect the actions to algorithms. (2C) T B Simplify numerical expressions involving order of operations and exponents (2E) T B. Use division to find unit rates and ratios in proportional relationships such as speed, density, price, recipes, and student-teacher ratio. (2D) Select and use appropriate operations to solve problems and justify the selections. (2F) T B Determine the reasonableness of a solution to a problem.

Use a fraction to represent division (i.e., each representation is read 2 divided by 3: 2/3 = 2 ÷ 3). D B **Basic Facts** - Recall and apply multiplication and division facts through 12 x 12. D B Use the commutative, associative, and distributive properties of addition and multiplication to explore mathematical relationships and solve problems (e.g.,, when calculating the perimeter of a rectangle as 2(l + w) or 2l + 2w. D B Identify greatest common factors of rational numbers to simplify expressions (e.g., 14/7 = 2 and 7/14 = 1/2). D B Use least common multiple to identify the least common denominator to add and subtract fractions with a non-negative solution. D B Apply multiplication and division of whole numbers in problems situations involving equivalent ratios and rates. D B Express numbers in scientific notation with positive exponents. D B
