4.1 Writing and Graphing InequalitiesFirst video: Students will write and graph inequalities.
Second video:Then they will use substitution to check whether a number is a solution of an inequality. |
4.2 Solving Inequalities Using Addition or SubtractionStudents will solve inequalities using addition or subtraction. Then they will graph their solution on a number line. Students will also solve real-world problems.

4.3 Solving Inequalities Using Multiplication or Division7.EE.4b
Students will solve inequalities using multiplication or division. Then they will graph their solution on a number line. Students will also solve real-world problems. |
4.4 Solving Two-Step Inequalities7.EE.4b
Students will solve multi-step inequalities and solve real-life problems. Then students will graph on a number line. |
Application to the Real WorldA killer whale has eaten 75 pounds of fish today. It needs to eat at least 140 pounds of fish each day. A buck holds 15 pounds of fish. Write and solve an inequality that represents how many more buckets of fish the whale needs to eat.
Should the whale eat four or five more buckets of fish? Explain |
