**Extension/Open-Ended Questions:**

Why is egg farming so important for Australia? Why do Australian people choose to buy eggs farmed in Australia?

**OVERVIEW**

In this lesson students will learn to describe displays by identifying categories of animals and the quantity and appearance of their eggs. They will represent data relating to hens and eggs laid on farms in Australia.

**AIMS & OBJECTIVES**

Upon completion of this lesson students will demonstrate a basic understanding of:

- Describing displays using mathematical data language
- Identifying and representing categories of animals and quantities of eggs using provided data

**Lesson Introduction:**

- Conduct the pre-test Pop Quiz.
- Introduce the concept to students that nearly all animals produce eggs, however only some of them lay eggs outside their body. They are called oviparous animals and include birds, insects, most reptiles, amphibians, some fish and some mammals. Of these oviparous animals, only some lay eggs that people eat commercially (buy from shops or restaurants).
- Using the interactive whiteboard activity Do We Eat These Eggs? students drag and drop a series of animals into the correct box labelled with a cross or a tick, depending on whether or not the animal lays eggs for human consumption.
- Once all animals have been placed into a category, discuss the results to determine if there were any surprises. Encourage students to recall a time they may have eaten any of the eggs.
- Using the interactive whiteboard activity, click onto each category of oviparous animals to find out more information about the quantity and appearance of the eggs laid, discuss.
- As a class, jointly construct a picture graph display to represent the data. Students describe the display, using mathematical data language, by identifying categories with the greatest and least amount of eggs.

**Main Body of Teaching:**

- Use the interactive whiteboard game, Eggs we Like to Eat, to display the variety of different birds that produce eggs. From this category students choose which birds lay eggs for general human consumption in Australia.
- Explain to students that in Australia, the most common choice of eggs used in cooking are hen’s eggs. Using the interactive whiteboard, students are presented with a map of states in Australia and the number of eggs used to represent the percentage laid in each state, Where Are Eggs Laid? Explain that there are farms in every state and city in Australia that produce eggs. Students play a simple game to find out which state lays the greatest and least amount of eggs each year. Drag and drop the number of eggs that represent how many eggs are farmed in that state each year.
- Also inform the students that 397 million dozen eggs are farmed each year and that 16.8 million hens are kept for commercial egg farming in Australia. Using the data from the previous activity, students create a simple pie graph representing the information relating to the percentage of egg farming for each state. Students describe the display, using mathematical data language by identifying which state produces the greatest and least amount of eggs each year.
- Ask the students who they think buys the eggs farmed in Australia and discuss possible answers. Students watch the online video Who Buys Australian Eggs? Illustrating how most of Australia’s eggs are bought by Australian people (also known as the domestic market). Briefly mention that people can buy eggs produced by hens in cages, barns and free range.

** Lesson Conclusion: **

- Display the graph, Which Country Produces the Most Eggs?, on the interactive whiteboard.
- Students describe the data using mathematical language by identifying which country farms the greatest and least amount of eggs.
- Using a 3-Dimensional globe, students locate the countries listed.
- Conduct the post-test Pop Quiz.

** Homework: **

- Work with a parent/caregiver to determine the amount of eggs eaten in a week by all members of your family.
- Use a grid to tally how many eggs were eaten on each day of the week (including eggs used in family meals).
- At the end of the week, create a simple picture graph to represent your data. Take your results to school and as a class calculate the amount of eggs consumed over the one week period.
