## The beach

End of Stage 1 (end of Year 2)

## Foundation Statement strands

The following strands are covered in this activity:

## Description of activity

Students construct a graph using the symbols provided and interpret the information presented.

The teacher presents the following scenario:

‘Karim went to the beach with his family last weekend. They walked along the shore and explored the rock pools. They saw many living things.’

1. Teacher displays a set of pictures on an overhead projector or as a large chart to show what Karim and his family saw at the beach.
2. Using this information, students construct a graph using a symbol to represent each animal.
3. Students use their graph to predict what they might see if they were to visit the same beach the following weekend.

The suggested time allocation for this activity is 60 minutes.

## Suggested materials

Scissors, glue, paper, pencils, crayons
Option: computer

## Prior learning

Students have sorted objects into groups and rows, organised the groups to aid comparison and compared groups by counting. They have collected information and organised it into a data display, then interpreted the information in the display to answer questions. Students have practised posing questions and using the language of chance when interpreting data.

## Outcomes

Chance (NS1.5)
Recognises and describes the element of chance in everyday events
Data (DS1.1)
Gathers and organises data, displays data using column and picture graphs, and interprets the results
Applying Strategies (WMS1.2)
Uses objects, diagrams, imagery and technology to explore mathematical problems
Communicating (WMS1.3)
Describes mathematical situations and methods using everyday and some mathematical language, actions, materials, diagrams and symbols
Reasoning (WMS1.4)
Supports conclusions by explaining or demonstrating how answers were obtained

## Criteria for assessing learning

Students will be assessed on their ability to:

• represent data in a graph
• interpret information presented in a graph
• use informal chance concepts
