**Curriculum – **Data Management and Probability

For students to sort, classify, and display a variety of concrete objects, collect data, begin to read and describe displays of data, and begin to explore the concept of probability in everyday contexts.

**Context**

Students begin by standing to the side of the carpet. Students should have a good understanding of sorting by characteristics and should have done the “Sorting Apples” lesson, which includes making a graph.

**Materials**

- “Sorting Apples” graph from the Sorting Apples Lesson.

**Lesson**

Introduction

- Tell students you will be sorting them by a characteristic and that their job is to find out what characteristic you are sorting by.

#### 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

- Show students the apple graph made during the previous lesson.
- Explain that graphs are meant to convey information easily to another person.
- Go through the necessary components of a graph. For example: title, column, rows, equal spacing between each section.
- It is not necessary to add numbers just yet.
