Circle to Bar Graph

Lesson
Introduction

• Have students go to different tables and work on transcribing the circle graph onto the bar graph.
• The last page of the circle to bar graph package will have questions about the graph.
  • For example: How many more robins did you have than cardinals?

Lesson

• Choose a characteristic (i.e. hair colour) and begin to sort children in columns. If you are sorting by hair colour, you might have three different columns – brown, blonde, and red.
• Ask children to stand in a straight line just like a soldier.
  • Ask children what characteristic you have sorted by.
• Ask children to sit in a circle and take off their shoes.
  • Put the shoes in a big pile.
  • Ask: “Is it easy to see to count the shoes when they are in a big pile?” Listen to their feedback.
• Put the shoes in a straight line.
  • Ask: “Is it easier to count the shoes when they are in a straight line?”
• Have students sort their own shoes using different characteristics (i.e. colour, size).
  • Children will take turns putting their own shoes in the appropriate column.

Closure

• When students finish filling in the graphs, they can practice asking each other questions about the graph.

Extension Activities
Tooth Graph

• Have tooth graph going throughout the year.
• Each child should have their own magnet with their name on it. As they loose a tooth they can move their name to the appropriate column.
• For example the graph can have the numbers 0 – 5 along the bottom.

Circle Weather Graph

• This works best in the month of November because in Canada that is typically when we witness the most diverse weather.
• Each day look out the window and put a mark in the appropriate section.
• Have students predict which type of weather they will get the most of in November.

Siblings Graph

• In small groups, build a sibling graph.
• Ask students how many siblings they have and have them put their mark in the appropriate place.
