Realize/Savvas Grade 4 Topic 3 Test

How can you break down a multiplication problem into simpler parts?

• By using the distributive property, which allows you to multiply each part of one factor by the other factor and then add the results.

• By simply adding the two numbers together.

• By dividing one of the numbers by the other.

• By using the associative property to group the numbers differently.

How do you estimate the product of two numbers?

• Round each number to the nearest ten or hundred and then multiply the rounded numbers.

• Add the two numbers together and then multiply by two.

• Subtract the smaller number from the larger number and then multiply by ten.

• Multiply the two numbers directly without rounding.

What is the value of the expression 8 × 42?

• 320

• 300

• 336

• 350

What is the process for solving word problems involving multiplication?

• Identify the quantities involved, determine what is being asked, and set up a multiplication equation based on the information provided.

• Only focus on the numbers given in the problem and ignore the context.

• Use addition instead of multiplication to find the solution.

• Read the problem multiple times without taking any notes.

How do you check your work after solving a multiplication problem?

• By adding the factors together

• By using the inverse operation (division)

• By multiplying the product by one of the factors

• By estimating the product using rounding

What is the relationship between multiplication and addition?

• Multiplication is a form of repeated addition.

• Multiplication is the inverse of addition.

• Multiplication is a method to find the difference between numbers.

• Multiplication is a way to divide numbers into equal parts.

What strategies can be used to solve complex multiplication problems?

• Breaking the problem into smaller parts

• Using a calculator for all calculations

• Ignoring the order of operations

• Rounding all numbers to the nearest ten

How do you find the total when given a repeated measurement, such as distance?

• Multiply the distance by the number of times it is repeated.

• Add the distance to itself for the number of times it is repeated.

• Divide the distance by the number of times it is repeated.

• Subtract the distance from the number of times it is repeated.

What is the importance of understanding units in word problems?

• It helps ensure that calculations are performed correctly and that the final answer is in the appropriate context (e.g., meters, cookies, cars).

• It allows for faster calculations without the need for units.

• It is only important in advanced mathematics, not in basic problems.

• It makes the problems more complicated and harder to solve.

What is a partial product in multiplication?

• A result of adding two factors together.

• The result of multiplying a single digit of one factor by the entire other factor.

• A method of dividing numbers into equal parts.

• The final product of a multiplication problem.
