# Sorting Material

## Curriculum Goal

#### Kindergarten: Demonstrating Literacy and Mathematics Behaviour

• Describe, sort, classify, build, and compare two-dimensional shapes and three-dimensional figures, and describe the location and movement of objects through investigation (#17).

## Context

• Students and teacher will be sitting on the carpet in a circle.
• Students will be working in pairs.

## Materials

• Different sets of materials (counters, small bears, buttons, etc.)
• One set for each pair

## Lesson

• Students will be working in pairs, with each pair assigned one type of material.
• Tell students that they are to sort that material by one characteristic in whichever way they choose.
• As children are sorting the materials, go around to each pair and ask how they sorted the material.
• Give students the language by saying you sorted by colour or you sorted by size or you sorted by shape.
• Then ask students to sort the materials using a different characteristic.
• When students have finished sorting ask them to explain to the group what characteristics they sorted by.

## Look Fors

• How do children work together to sort the materials?
• Can they verbalize the characteristic they used?
• Are there any unique ways children divide materials into groups? Are they able to divide materials into a new way using a different characteristic?

## Extension

• Take away one group from the sorted material and ask students to re-sort their material using a different characteristic.
• Challenge students by having them try this activity with two different materials together.

## Related Lessons

Foster students understanding of sorting objects by various characteristics.

Students practice identifying the sorting characteristics among two groups.
