I didn’t really need to have the slides in their without the color coding but for more advanced students, they may be able to run with this concept after the first example.
Depending on the ability level in your class, students may run through this pretty quickly and so you may need to add more examples for students to practice on their own or as homework.
Go to [slide 7] and have a student solve and graph.
Have students then try the problem on [slide 8/slide 9] on their own.
Examples, solutions, worksheets, videos, and lessons to help Grade 7 students learn how to use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. Solve word problems leading to inequalities of the form For example: As a salesperson, you are paid $50 per week plus $3 per sale. Write an inequality for the number of sales you need to make, and describe the solutions Solving Inequalities by Adding or Subtracting When you add or subtract the same number from each side of an inequality, the inequality remains true.

I never needed anyone to do my homework for me until I got a part-time job in college.may consist of several pages, scroll down to the see everything. If your school has some weird security settings, you can always print the worksheet right-clicking over the Worksheet and selecting "Print". If you don't see it, you may have the toolbar set to "off", just click the F8 key to see it.Step 1: Let the number of tiles he want to buy be x Step 2: Cost of each tile = Cost of x tiles = 4 × x = 4x Step 3: Amount he can spend is ≤ 00 So cost of tiles has to be less than or equal to 00 4x ≤ 1200 Step 4: Dividing both sides by 4 4x/4 ≤ 1200/4; x ≤ 300 So the solution of this inequality is x ≤ 300; The contractor can buy a maximum of 300 tiles. In 5 years, Sarah will be old enough to vote in an election. [Slide 2] Have students read the problem and then ask where they should start. From there, we have all of the pieces of the inequality in order and we can easily write the inequality. On this slide, I’ve color coded the words in the problem to the list on the left so that students can easily match up what goes together. All the numbers to the right of the number on the line are greater than the number.[Values increase from left to right on a number line.] The graph with the open dot on a number shows that the number is not a solution of the inequality and the graph with the closed dot on a number shows that the number is a solution of the inequality.The color coding was the most helpful thing to get their brains matching up phrases with parts of an inequality.This also turns out to be great for future lessons on slope-intercept form and rate of change.
