[FREE] End of Year Math Assessments (Grade 4 and Grade 5)

The assessments cover a range of topics to assess your students' math progress and help prepare them for state assessments.

Here you will learn about solving inequalities, including how to solve linear inequalities, identify integers in the solution set, and represent solutions on a number line.

Students will first learn about solving simple inequalities as part of expressions and equations in 6th grade math and expand that knowledge in 7th grade math.

**Solving inequalities** allows you to calculate the values of an unknown variable in an inequality.

Solving inequalities is similar to solving equations, but where an equation has one unique solution, an inequality has a range of solutions.

In order to solve an inequality, you need to balance the inequality on each side of the inequality sign in the same way as you would balance an equation on each side of the equal sign. Solutions can be integers, decimals, positive numbers, or negative numbers.

For example,

How does this relate to 6th grade and 7th grade math?

**Grade 6 – Expressions and Equations (6.EE.B.8)**Write an inequality of the form x > c or x < c to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x < c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.

**Grade 7 – Expressions and Equations (7.EE.4b)**

Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem.

For example: As a salesperson, you are paid \$50 per week plus \$3 per sale. This week you want your pay to be at least \$100. Write an inequality for the number of sales you need to make, and describe the solutions.

In order to solve inequalities:

**Rearrange the inequality so that all the unknowns are on one side of the inequality sign.****Rearrange the inequality by dividing by the**\textbf{x}**coefficient so that**\textbf{‘x’}**is isolated.****Write your solution with the inequality symbol.**

**Rearrange the inequality so that all the unknowns are on one side of the inequality sign.**

In this case you are subtracting 6 from both sides.

This leaves 4x on the left side of the inequality sign and 20 on the right side.

2**Rearrange the inequality by dividing by the ** \textbf{x} ** coefficient so that ** \textbf{‘x’} ** is isolated.**

In this case you need to divide both sides by 4.

This leaves x on the left side of the inequality sign and 5 on the right side.

3**Write your solution with the inequality symbol.**

Any value less than 5 satisfies the inequality.

Solve:

This leaves 5x on the left side of the inequality sign and 30 on the right side.

**Rearrange the inequality by dividing by the ** \textbf{x} ** coefficient so that ** \textbf{‘x’} ** is isolated.**

In this case you need to divide both sides by 5.

**Write your solution with the inequality symbol.**

Any value greater than or equal to 6 satisfies the inequality.

Solve:

**Rearrange the inequality so that all the unknowns are on one side of the inequality sign.**

Let’s start by expanding the parentheses.

Then you need to add 12 to both sides.

This leaves 3x on the left side of the inequality sign and 24 on the right side.

**Rearrange the inequality by dividing by the ** \textbf{x} ** coefficient so that ** \textbf{‘x’} ** is isolated.**

In this case you need to divide both sides by 3.

Solve:

**Rearrange the inequality so that all the unknowns are on one side of the inequality sign.**

This leaves 3x-6 on the left side of the inequality sign and 15 on the right side.

**Rearrange the inequality so that ** \textbf{‘x’} **s are on one side of the inequality sign and numbers on the other.**

In this case you need to add 6 to both sides.

This leaves 3x on the left side of the inequality sign and 21 on the right side.

**Rearrange the inequality by dividing by the ** \textbf{x} ** coefficient so that ** \textbf{‘x’} ** is isolated.**

In this case you need to divide both sides by 3.

This leaves x on the left side of the inequality sign and 7 on the right side.

**Write your solution with the inequality symbol.**

Any value greater than 7 satisfies the inequality.

Solve:

**Rearrange the inequality to eliminate the denominator.**

In this case you need to multiply both sides by 5.

**Rearrange the inequality so that ** \textbf{‘x’} **s are on one side of the inequality sign and numbers on the other.**

In this case you need to subtract 3 from both sides.

**Rearrange the inequality by dividing by the ** \textbf{x} ** coefficient so that ** \textbf{‘x’} ** is isolated.**

**Write your solution with the inequality symbol.**

Any value greater than or equal to \, \cfrac{1}{2} \, satisfies the inequality.

Represent the solution on a number line:

** Rearrange the inequality so that ** \textbf{‘x’}

In this case you need to add 7 to both sides.

**Rearrange the inequality by dividing by the ** \textbf{x} ** coefficient so that ** \textbf{‘x’} ** is isolated.**

Any value less than 6 satisfies the inequality. An open circle is required at 6 and the values lower than 6 indicated with an arrow.

Solve:

**Rearrange the inequality so that ** \textbf{‘x’} **s are on one side of the inequality sign and numbers on the other.**

In this case you need to subtract 1 from both sides.

**Rearrange the inequality by dividing by the ** \textbf{x} ** coefficient so that ** \textbf{‘x’} ** is isolated.**

In this case you need to divide both sides by negative 2.

6 \div-2=-3

**Change the direction of the inequality sign.**

Because you divided by a negative number, you also need to change the direction of the inequality sign.

List the integer values that satisfy:

**Rearrange the inequality so that all the unknowns are on one side of the inequality sign.**

In this case you need to subtract 1 from each part.

**List the integer values satisfied by the inequality.**

**Rearrange the inequality so that ** \textbf{‘x’} ** is isolated. In this case you need to divide each part by ** \bf{2} **.**

**Represent the solution set on a the number line**

-4 is not included in the solution set so requires an open circle. 1 is included in the solution set so requires a closed circle.

Put a solid line between the circles to indicate all the values that satisfy the solution set.

- Students should master solving simple inequalities (one-step inequalities) before moving on to two-step inequalities (or multi-step inequalities).

- Foster student engagement by practicing solving inequalities through classroom games such as BINGO rather than daily worksheets.

- Student practice problems should have a variety of inequalities such as inequalities with fractions, negative numbers, and parentheses. (see examples above)

**Solutions as inequalities**

Not including the inequality symbol in the solution is a common mistake. An inequality has a range of values that satisfy it rather than a unique solution so the inequality symbol is essential.

For example, when solving x + 3 < 7 giving a solution of 4 or x = 4 is incorrect, the answer must be written as an inequality x < 4 .

**Balancing inequalities**

Errors can be made with solving equations and inequalities by not applying inverse operations or not balancing the inequalities. Work should be shown step-by-step with the inverse operations applied to both sides of the inequality.

For example, when solving x + 3 < 7 , adding 3 to both sides rather than subtracting 3 from both sides.
