For the DO NOW problem, I’m going to have the students make a list of characteristics of previously learned graphs. For example, they can list all the elements in a line graph, bar graph, or line plot. (SMP 6) I will be using this for closure at the end when I have them create their Venn diagram. I’m looking for the following:
Line graph – shows change over time, x and y axis, labels, titles, connected lines and dots, can predict, equal intervals, scale starts at zero
Bar graph – shows popularity, x and y axis, labels, titles, separated bars, equal intervals, scale starts at zero, can see the mode
Line Plot – shows frequency, uses a number line and x’s or dots, title, label, can see median and mode
Students can share their responses with a partner to ensure enough information is collected.
My thoughts for the middle part of the lesson are to have the students answer questions about the graphs and discover the elements on their own. Then they will use this knowledge to create their own circle graph and venn diagram. So for this lesson, I’m going to reference the slide number and the questions I will ask to get the students to critically and mathematically think of the display shown. (SMP 1, 2, 5, 6)
Slide 4 – Favorite Color (Circle graph with recognizable portions or benchmarks)
Slide 5 – Favorite Pet(More sections and only a few benchmarks. Students will need to reason out the other sections)
Slide 6 – Favorite Pizza topping (Benchmark portions, but with 200 people surveyed)
Slide 8 Venn Diagram – 4 sided figures
Slide 9 – Factors of 18 and 24
Slide 10 – Favorite team (cubs and sox)
After the notes, have the students find a partner and work on the around the room or use it with white boards for a more formal assessment. The around the room is in a power point. If using for ATR, then print out a slide per page and hang around the room. If using with white boards, then use as a power point.
Students will be working in pairs to complete 12 problems involving analyzing data in a circle graph and in a Venn Diagram.
The students will be using data to create their own circle graph and venn diagram. Collect this from them to show evidence of student learning.
Create your own circle graph with the following data. Out of 100 people surveyed when asked what their favorite season was…
25 chose winter
25 chose fall
50 chose summer
Create a Venn diagram comparing and contrasting line graphs, line (dot) plots, or bar graphs. Choose any two. Use the information from the DO NOW.
