Making Bar Graphs: Graph It!
The students will be able to use a bar graph to represent data.
- Explain to your students that they are going to be asked a question to create a special bar graph for the class.
- Explain to students how bar graphs help us view data in an organized and readable way.
Explicit Instruction/Teacher modeling(25 minutes)
- Hand out a sticky note to each student.
- Have the student write their favorite ice cream flavour on the sticky note.
- Once all students have finished, have the students come up front to place the sticky note on the board.
- Start reading the sticky notes and organise them into columns by flavour, creating a bar graph.
- Once you have all the sticky notes organized, use a dry erase marker to create the bar graph with the numbers on the Y-axis, or the vertical axis, and the flavors on the X-axis, or the horizontal axis.
- Once the graph is complete on the board, review to make sure the data is accurate by having the students stand up when you call their favorite ice cream. Have the students who are sitting count the standing students to confirm the graph on the board has the correct data.
Guided practise(10 minutes)
- Pass out the My Class Ice Cream Graph worksheet to each student and have them transfer the data from the board onto the document.
- Have the students designate a colour for each flavour to colour in the bars of the graph.
Independent working time(5 minutes)
- Pass out the Favorite Cake Bar Graph worksheet to each student.
- Have the students complete the worksheet independently or with a partner.
- Walk around the room to monitor students and help as needed.
- Enrichment:Challenge advanced students to create a class or school survey and create a bar graph to represent the data they collected.
- Support:Partner a student who needs support with a student who is at grade level.
- Use the Beginning Bar Graphs: Favorite Sports worksheet to assess students formally or informally by having them complete the graph independently.
Review and closing(5 minutes)
- As a review, repeat the class graph activity by asking the class to write down a different "favorite" on a sticky note.
- Another review option is to set up a work station with graphing worksheets so students can work on them in a group setting.
