Section CLXXI-1101 - Operations and Algebraic Thinking

A. Interpret a multiplication equation as a comparison and represent verbal statements of multiplicative comparisons as multiplication equations, e.g., interpret 35=5 x 7 as a statement that 35 is 5 times as many as 7, and 7 times as many as 5.

B. Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and/or equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.

Example: 6 times as many vs. 6 more than

C. Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

Example: Twenty-five people are going to the movies. Four people fit in each car. How many cars are needed to get all 25 people to the theater at the same time?

D. Using Whole Numbers in the Range 1-100

1. Find all factor pairs for a given whole number.

2. Recognize that a given whole number is a multiple of each of its factors.

3. Determine whether a given whole number is a multiple of a given one-digit number.

4. Determine whether a given whole number is prime or composite.

E. Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself.

Example: Given the rule "Add 3" and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.)
