The Exit Slip ask for students to provide feedback on anything they learned from this activity, or anything that they taught another student. I expect the Independent Practice to take about 15 minutes. However, when looking at a graph, students have more difficulty.

Warm Up-stating domain and range with set builder notation. It is a handful of students that are still struggling, but it relates back to not understanding the meaning of the inequality symbols.

Express your answers in interval notation by graphing the solution on a number line to determine the upper and lower bounds of the variable.

Exit slip-domain and range using set builder notation. Then I ask the students who get all three questions correct to stand up. We check the problems again, and I call on students to come to the board to model the problems. Having a clear understanding of what the inequalities symbols mean, will help my students to achieve the goal of this lesson: He has written for the Guide to Online Schools website, covering academic and professional topics for young adults looking at higher-education opportunities.

I call on students as we work through the Guided Practice. I instruct them to start by trying to provide feedback to correct any of the first three answers that they missed, but then compare other answers on each others paper to look for differences.

I start off working and modeling a few problems, and then let them try one before we check it. One color for domain and one color for range. I have students use two colored pencils for this activity. I review the Warm Up in the video below: I also assist students that need more help with the inequality symbols when using set builder notation.

Intervals with parentheses are called open intervals, meaning the variable cannot have the value of the endpoints. I allow everyone time to finish the Independent Practice.

I purposely planned for the students to use set builder notation first to develop a deeper understanding of inequalities before working with interval notation. I instruct each of them to find a table or an individual student that is not standing, and give them feedback on their paper.

After students have completed the Practice, I show the students the first three answers to numbers 1, 2, and 3. I think that the one on one peer feedback was beneficial. I use it to access their prior knowledge of inequalities or refresh their memory if necessary.

I did hear good feedback and conversations between students, explaining the inequality symbols. Some of the students that are writing their answers in interval notation, are not using the parentheses or the square brackets correctly either.

I ask students how far left, and how far right does the graph go for domain. After the five minutes is up, I have students complete the Exit Slip. I model an example below in the video: For range, I ask how low does the graph go to how high does it go.

Guided Practice-domain and range using set builder notation. Then after reviewing the one problem they work individually, I assign them two or three problems to work individually. I emphasize equal to or includes, as well as not equal toand does not include. Most of the student responses on the Exit Slip indicated students still having problems with the meaning of the inequality symbols.

Tip If there are other intervals of the variable, connect them with the union symbol "v. This is definitely a skill that I will keep checking. Wallulis holds a Bachelor of Arts in psychology from Whitman College.

Some students I notice are writing the intervals for domain and range in interval notation instead of set builder notation. I remind students to place their answers in set builder notation, which they have problems doing.Write the interval notation for: What about?

I allow everyone time to finish the Independent Practice. The formatting of the above answer is called "inequality notation", because the solution is written as an inequality.

This is probably the simplest of the solution notations, but there are three others with which you might need to be familiar.

"Set notation" writes the solution as a set of points. The above solution would be written in set. How do you write the set in roster form and in set builder notation? - 1. Log in Join now 1.
