3.NBT.A3
Multiply one-digit whole numbers by multiples of 10 in the range 10-90 (e.g., 9 x 80, 5 x 60) using strategies based on place value and properties of operations.
October 1, 20183.OA.A2
Interpret whole-number quotients of whole numbers, e.g., interpret 56 (square root) 8 as the number of objects in each share when 56 objects are partitioned equally into 8 shares, or as a number of shares when 56 objects are partitioned into equal shares of 8 objects each. For example, describe a context in which a … Read More “3.OA.A2”

Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 _ ? = 48, 5 = _ (square root) 3, 6 _ 6 = ?
October 1, 20183.OA.B6
Understand division as an unknown-factor problem. For example, find 32 (square root) 8 by finding the number that makes 32 when multiplied by 8.
October 1, 20183.OA.C7
Fluently multiply and divide within 100, using strategies such as the relationship between multiplication and division (e.g., knowing that 8 _ 5 = 40, one knows 40 (square root) 5 = 8) or properties of operations. By the end of Grade 3, know from memory all products of two one-digit numbers.
October 1, 20184.NF.A1
Explain why a fraction a/b is equivalent to a fraction (n x a)/(n x b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

(+) Develop a probability distribution for a random variable defined for a sample space in which probabilities are assigned empirically; find the expected value. For example, find a current data distribution on the number of TV sets per household in the United States, and calculate the expected number of sets per household. How many TV … Read More “HSS.MD.A4”

(+) Weigh the possible outcomes of a decision by assigning probabilities to payoff values and finding expected values.
October 1, 2018HSS.MD.B5a
Find the expected payoff for a game of chance. For example, find the expected winnings from a state lottery ticket or a game at a fast-food restaurant.
October 1, 2018HSS.MD.B5b
Evaluate and compare strategies on the basis of expected values. For example, compare a high-deductible versus a low-deductible automobile insurance policy using various, but reasonable, chances of having a minor or a major accident.
October 1, 2018HSS.MD.B6
(+) Use probabilities to make fair decisions (e.g., drawing by lots, using a random number generator).
October 1, 2018HSS.MD.B7
(+) Analyze decisions and strategies using probability concepts (e.g., product testing, medical testing, pulling a hockey goalie at the end of a game).
