Multiply & Divide Whole Numbers

Grade: 5th Grade
Standard:

Math.5.NBT.5 or 5.NBT.B.5

Description:

Fluently multiply multi-digit whole numbers using the standard algorithm.

Standard:

Math.5.NBT.6 or 5.NBT.B.6

Description:

Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

Standard:

Math.5.NF.3 or 5.NF.B.3

Description:

Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem. For example, interpret 3/4 as the result of dividing 3 by 4, noting that 3/4 multiplied by 4 equals 3, and that when 3 wholes are shared equally among 4 people each person has a share of size 3/4. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Between what two whole numbers does your answer lie?
