Summer SAVY, Session 3 Day 2, The One to Beat (3rd – 4th)

Posted by on Tuesday, June 25, 2024 in blog, SAVY.

Hello SAVY parents!

Yesterday, students created a foldable that would allow them to remember vocabulary terms that we will discuss this week. Today, we added two new vocabulary terms to our word wall: rate of change and y-intercept.

The class started with a recap of yesterday’s orange-nose push challenge. Students were given a new line graph to represent the challenge, and as a whole group, we discussed the similarities and differences between the graphs. Real-world situations were given where students were able to look at the graph to determine the rate of change, interpret the information by looking at the shape of the line, and identify how the variables affect one another in each situation.

The overall theme of the morning session was for the students to be able to interpret what information could be obtained from the shape of the line. In graphs where the line did not start at the origin, students could predict that someone had a different starting position. In our last morning activity, six graphs were posted around the room, and the students had to identify which graph matched the real-world situations they were given. Students were also able to list the variables in each situation and describe the change that was happening in each graph.

In the afternoon session, students learned how to look at tables as another way to analyze the change between variables in a situation. We were able to compare/contrast line graphs and tables. Students were also given questions that they could ask themselves when trying to decide the most appropriate graph to use in various situations. When displaying change over time a line graph is most appropriate, but when displaying the data for a single event, a table should be used. Tables are most useful in helping us to more easily recognize patterns in numbers and analyze how one variable is changing with respect to another.

In tomorrow’s session, our study will involve a dog named Olive Oyl that made the record books for jumping 63 times when jumping rope in one minute. Stay tuned to find out who will break tomorrow’s record!

Thank you so much for another successful day, and I look forward to another day of fun and learning.

Questions to Consider:

• Which type of graph is best used for displaying change over time?
• How does the absence of the scale affect how you identify variables on a graph in a given situation?
• What operation should be performed when an algebraic equation includes a number and a variable side by side?
• What was the relationship between time and distance on the Orange Nose Push graph?
• Describe a real-world situation where the graph might not begin at the origin.

With children first!
