Viewers will learn how to graph lines, such as y=2x+1. The instructor emphasizes the relationship between the x and y variables, creates an x/y table, and finally graphs the equation. A total of three examples are given in this video.
Sal takes viewers through another example of graphing rational functions "because you really can't get enough practice here." Combined with the two previous videos on graphing rational functions and asymptotes, viewers will walk away with a strong grasp on the concept and its process.
In this short video, Sal shows how to graph a line in slope-intercept form.
Get to know your class and teach about data analysis all with the help of Google Docs. Using student-generated questions, create a class survey using Google Forms. Reserve time in the computer lab for learners to complete the form and, amazingly, Google will compile and graph the responses automatically! Display and discuss the results as a whole class, making comparisons and answering questions about the data. A great activity for the first week of school that uses technology to engage children in learning about math.
Teaching young mathematicians about collecting and analyzing data allows for a variety of fun and engaging activities. Here, children observe the weather every day for a month, recording their observations in the form of a bar graph. When they are done, the class discusses the data they collected, answering questions and comparing the number of days each type of weather was observed. The emphasis of the activity is on building the academic language of children as they learn to interpret data. Coordinate this math lesson series with a science unit on weather, enriching student learning with cross-curricular connections between the two subjects.
Turn your algebra learners into meteorologists. Students are given three graphs that contain information about the weather in Santa Rosa, California during the month of February, 2012. Graph one shows temperatures, graph two displays the solar radiation, and graph three indicates the amount of rainfall. Your future meteorologists are to first describe the function of each graph and then make a connection between all three graphs.
After making a correction to the last problem in his previous video, Sal explains how to graph quadratic functions. Those who have a hard time with the concept of graphing algebraic functions will find Sal's instruction and easygoing manner a welcome change from staring at textbooks.
Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.
If your class struggles with graphing inequalities, or if your lecture could use some help from Sal, this video would be a great help. Sal's instruction is measured and patient, and viewers will walk away feeling more confident and successful in their graphing skills.
Sal teaches how to use graphing as a tool, not a hindrance, in this helpful video. His lecture would make be a good resource for your algebra class, particularly as the focus shifts to graphing problems and linear systems.
Sal takes viewers through another example of graphing rational functions "because you really can't get enough practice here." Combined with the two previous videos on graphing rational functions and asymptotes, viewers will walk away with a strong grasp on the concept and its process.
First taking viewers through the process of graphing using intercepts, Sal then works to graph a word problem. His process is so fluid and easy to understand that all mathematicians, beginning and advanced, could benefit from watching his methods.
How many yellow Skittles® come in a fun-size package? Use candy color data to construct a bar graph and a pie chart. Pupils analyze bar graphs of real-life data on the Texas and Massachusetts populations. As an assessment at the end of the instructional activity, they gather sports data from the CNN/Sports Illustrated website to graph. At the beginning of the year, it is helpful to revisit graphing skills with mathematicians and scientists; this is an engaging instructional activity for doing just that!
Young scholars explore graph theory.  In this geometry lesson,  graphs are used to solve problems in a variety of domains.  In this lesson the term graph refers to a collection of vertices and edges used to depict travel routes.
In this graphs worksheet, students answer 15 multistep questions about graphs.  Students determine distance traveled, time, velocity, and create scenarios to fit the graph.
In this statistics learning exercise, students explore the characteristics of line graphs, bar graphs, circle graphs and the coordinate plane. Afterwards, they graph ordered pairs on a coordinate plane. Students then create a line graph, bar graph, and pie chart from given information. They answer questions and interpret graphed information. This five-page learning exercise contains three multi-step problems. Answers to the graphs are provided on page five of the learning exercise.
Students identify real graphs and misleading graphs. In this algebra lesson, students surf the Internet for real life scenarios where graphs are used in a misleading way as well as in a correct way.
By using hands-on graphing lesson plans students can learn how to collect data, and display the information using graphs.
In this bar graph worksheet, students read about making quality bar graphs and they make a bar graph using given data. They answer 5 questions about their graph.
Data collection and the construction of bar graphs are the focus of this math lesson. First and second graders tally responses from questions to the group and review different types of graphs. They visit a website to select and print a graph of their choice.
