4.) Understand the relationship between numbers and quantities; connect counting to cardinality. [KCC4]
a. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. [KCC4a]
b. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted. [KCC4b]
c. Understand that each successive number name refers to a quantity that is one larger.

Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known (Commutative property of addition)
To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12 (Associative property of addition)

12  8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13). [1OA6]

23.) Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement. [4MD5]
a. An angle is measured with reference to a circle with its center at the common endpoint of the rays by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through ^{1}/_{360} of a circle is called a "onedegree angle" and can be used to measure angles. [4MD5a]

17.) Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. (Students able to multiply fractions in general can develop strategies to divide fractions in general by reasoning about the relationship between multiplication and division. However, division of a fraction by a fraction is not a requirement at this grade.)
[5NF7]
a. Interpret division of a unit fraction by a nonzero whole number, and compute such quotients. [5NF7a]
Example: Create a story context for (^{1}/_{3}) ÷ 4, and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that (^{1}/_{3}) ÷ 4 = ^{1}/_{12} because (^{1}/_{12}) x 4 = ^{1}/_{3}.
b. Interpret division of a whole number by a unit fraction, and compute such quotients. [5NF7b]
Example: Create a story context for 4 ÷ (^{1}/_{5}), and use a visual fraction model to show the quotient. Use the relationship between multiplication and division to explain that 4 ÷ (^{1}/_{5}) = 20 because 20 x (^{1}/_{5}) = 4.
c. Solve realworld problems involving division of unit fractions by nonzero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem. [5NF7c]
Examples: How much chocolate will each person get if 3 people share ^{1}/_{2} lb of chocolate equally? How many ^{1}/_{3} cup servings are in 2 cups of raisins?

b. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes. [6NS6b]
c. Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane. [6NS6c]

10.) Understand ordering and absolute value of rational numbers. [6NS7]
a. Interpret statements of inequality as statements about the relative position of two numbers on a number line diagram. [6NS7a]
Example: Interpret 3 > 7 as a statement that 3 is located to the right of 7 on a number line oriented from left to right.
b. Write, interpret, and explain statements of order for rational numbers in realworld contexts. [6NS7b]
Example: Write 3^{o}C > 7^{o}C to express the fact that 3^{o}C is warmer than 7^{o}C.
c. Understand the absolute value of a rational number as its distance from 0 on the number line; interpret absolute value as magnitude for a positive or negative quantity in a realworld situation. [6NS7c]
Example: For an account balance of 30 dollars, write 30 = 30 to describe the size of the debt in dollars.
d. Distinguish comparisons of absolute value from statements about order. [6NS7d]
Example: Recognize that an account balance less than 30 dollars represents a debt greater than 30 dollars.

a. Write expressions that record operations with numbers and with letters standing for numbers. [6EE2a]
Example: Express the calculation, "Subtract y from 5," as 5  y.
b. Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity. [6EE2b]
Example: Describe the expression 2(8 + 7) as a product of two factors; view (8 + 7) as both a single entity and a sum of two terms.
c. Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in realworld problems. Perform arithmetic operations, including those involving wholenumber exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). [6EE2c]
Example: Use the formulas V = s^{3} and A = 6s^{2} to find the volume and surface area of a cube with sides of length s = ^{1}/_{2}.

5.) Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers. [7NS2]

Interpret products of rational numbers by describing realworld contexts. [7NS2a]
b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with nonzero divisor) is a rational number. If p and q are integers, then  (^{p}/_{q}) = ^{(p)}/_{q} = ^{p}/_{(q)}. Interpret quotients of rational numbers by describing realworld contexts. [7NS2b]
c. Apply properties of operations as strategies to multiply and divide rational numbers. [7NS2c]

9.) Solve multistep reallife 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. [7EE3]
Examples: 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.

Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. [7EE4a]
Example: The perimeter of a rectangle is 54 cm. Its length is 6 cm. What is its width?
b. Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality, and interpret it in the context of the problem. [7EE4b]
Example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.

41.) Construct and interpret twoway frequency tables of data when two categories are associated with each object being classified. Use the twoway table as a sample space to decide if events are independent and to approximate conditional probabilities. [SCP4]
Example: Collect data from a random sample of students in your school on their favorite subject among mathematics, science, and English. Estimate the probability that a randomly selected student from your school will favor science given that the student is in tenth grade. Do the same for other subjects and compare the results.

Example: The amount of sales tax on a new car is directly proportional to the purchase price of the car. If the sales tax on a $20,500 car is $1,600, what is the purchase price of a new car that has a sales tax of $3,200?
Answer: The purchase price of the new car is $41,000.
