7th Grade Math Assessment Practice Overview

This video tutorial covers a seventh-grade math assessment review. It includes instructions on measuring the length of a bar, solving absolute value expressions, using order of operations, finding true equations for ordered pairs, solving for missing numbers, and calculating probability with a six-sided die. Each section provides step-by-step guidance and examples to help students understand and solve the problems effectively.

How do you find the actual length of a bar when it doesn't start at 0?

• Multiply the starting and ending points

• Add the starting point to the ending measurement

• Subtract the starting point from the ending measurement

• Divide the ending point by the starting point

How do you measure the length of a bar that doesn't start at 0?

• Guess the length based on the scale

• Only measure the visible part of the bar

• Start measuring from the beginning of the ruler

• Measure from 0 to the end and subtract the starting point

What does the absolute value of a number represent?

• Its division factor

• Its multiplication factor

• Its distance from 0 on a number line, always positive

• Its subtraction value from 100

What does an absolute value equation look like?

• x / y = z

• x - y = z

• x^2 = y

• |x| = y

In order of operations, what should be completed first?

• Subtraction

• Addition

• Multiplication or Division, whichever comes first from left to right

• Parentheses and exponents

What is the first step in solving an equation with a negative number outside parentheses?

• Add the numbers inside the parentheses

• Divide the negative number by the sum inside the parentheses

• Subtract the numbers inside the parentheses

• Multiply the negative number by the sum inside the parentheses

Which operation is not immediately affected by the presence of parentheses?

• None, all are affected

• Multiplication

• Subtraction

• Addition

How can you determine which equation matches all ordered pairs in a table?

• Guess and check

• Test each equation with all pairs

• Only use the first pair

• Use the last pair only

How do you solve for an unknown number in a multiplication equation?

• Subtract the known numbers

• Multiply the known numbers

• Add the known numbers

• Divide the product by one of the known numbers

What is the probability of rolling a four or higher on a six-sided die?

• 1/6

• 1/2

• 1/3

• 2/3
