# Summary:

In this lesson students will investigate ratios reducing or increasinng the size of numbers through designing and creating their own Dice Football team with their own Team Name, Team Jumpers and Salary Cap!

• Convert between common metric units of length, mass and capacity (ACMMG136)
• Select and apply efficient mental and written strategies and appropriate digital technologies to solve problems involving all four operations with whole numbers      (ACMNA123)
• Recognise and solve problems involving simple ratios      (ACMNA173)

# Lesson:

Introduction:
1. Give students out the team design sheet and tell them to design and colour in thier jumper as well as come up with a team name, there 5 best players (can be anyone!) and there major sponsor.
Body:
1. Model to the students how to draw a grid over the top of the jumper. The grid will contain 1cm squares over the top (4 x 5) **Make sure it is light so that it can be rubbed out easily and wont ruin the great design!
2. On an A3 sheet of paper get the students to draw a grid where the squares are 7cm x 7cm.
3. This is where you explain to the students we are blowing up the jumper at a ratio od 1:7** great chance to show students how ratios can make things bigger and smaller.
4. Now model to the students how to “blow up” your jumper to a greater scale by drawing whats in each square.
5. Once they have transferred to the jumper to A3 size they need to colour these again.
6. An extension: Your major sponsor has given you \$5,000,000 salary cap to start your team. You must pay your best player \$500,000 and you must pay your “leadership group” more than your regular players. Create a table of each player and how much they will get paid-Great mental arithmetic for them, plus a good engagement and introduction to the world of AFL salary caps.

Conclusion:

1. Up on completion, you can turn these into a poster to hang around the classroom, as well as the team design sheet now forms a round robin tournament to be played in class.

For an example of a finished poster and team competition see photos in resources.

# Assessment:

• Anecdotal notes plus the finished poster will give you a good indication.
