Grade: 4

Enduring Skill 1:

Interpret a multiplication equation as a comparison,

e.g., interpret 35 = 5 × 7 as a statement that 35 is 5

times as many as 7 and 7 times as many as 5.

Represent verbal statements of multiplicative

comparisons as multiplication equations.

Demonstrators:

1.

Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a

statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal

statements of multiplicative comparisons as multiplication equations.

2.

Multiply or divide to solve word problems involving multiplicative comparison, e.g., by

using drawings and equations with a symbol for the unknown number to represent the

.

problem, distinguishing multiplicative comparison from additive comparison

3.

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.

4. Find all factor pairs for a whole number in the range 1-100. Recognize that a whole

number is a multiple of each of its factors. Determine whether a given whole number in

the range 1-100 is a multiple of a given one-digit number. Determine whether a given

whole number in the range 1-100 is prime or composite.

5.

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. For example, given the rule

“Add 3” and the starting number 1, generate terms in the resulting sequence and

observe that the term appear to alternate between odd and even numbers. Explain

informally why the numbers will continue this way.

6. Recognize that in a multi digit whole number, a digit in one place represents ten times

what it represents in the place to its right. For example,700/70 = 10 apply concepts of

place value and division.
