Mathematical Practices: 1. Make sense of problems and persevere in solving them. 2. Reason abstractly and quantitatively. 3. Construct viable arguments and critique the reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure. 8. Look for and express regularity in repeated reasoning.Common Core MathematicsGrade 4Mathematical Practices
4.MD.2. Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.Common Core MathematicsGrade 4Measurement And DataSolve Problems Involving Measurement And Conversion Of Measurements From A Larger Unit To A Smaller Unit

6.NS.5. Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.Common Core MathematicsGrade 6The Number SystemApply And Extend Previous Understandings Of Numbers To The System Of Rational Numbers
6.NS.6. Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.Common Core MathematicsGrade 6The Number SystemApply And Extend Previous Understandings Of Numbers To The System Of Rational Numbers

7.EE.3. Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies. For example: If a woman making $25 an hour gets a 10% raise, she will make an additional 1/10 of her salary an hour, or $2.50, for a new salary of $27.50. If you want to place a towel bar 9 3/4 inches long in the center of a door that is 27 1/2 inches wide, you will need to place the bar about 9 inches from each edge; this estimate can be used as a check on the exact computation.Common Core MathematicsGrade 7Expressions And EquationsSolve Real-Life And Mathematical Problems Using Numerical And Algebraic Expressions And Equations

1.8 Use concepts of negative numbers (e.g., on a number line, in counting, in temperature, in “owing”).CA MathematicsGrade 401. Number Sense1.0 Students understand place value of whole numbers and decimals to two decimal places, how these relate to simple fractions, and use concepts of negative numbers.
1.5 Identify and represent on a number line decimals, fractions, mixed numbers, and positive and negative integers.CA MathematicsGrade 501. Number Sense1.0 Students compute with very large and very small numbers, positive integers, decimals, and fractions and understand the relationship between decimals, fractions, and percents. They understand the relative magnitudes of numbers.
