Rating the tasks
This lesson contains a few activities. Each activity will have one or more tasks. These tasks have been given a rating.
Some of the tasks in this lesson are must do. These are important to help you understand the introductory ideas or skills.
Have a go at the should do tasks and reach out to your friends or teacher if you need some advice. These will usually take a bit longer to complete than must do tasks.
Could do tasks will probably take you some extra time and might need you to get creative or problem solve. We strongly encourage you to try these.
Activity 1 - Rock, paper, scissors
Task 2
Use the interactive cards on the right to remind yourself of some key definitions.
Use the embedded Rock, paper, scissors simulator below to play the game. (If the embed isn't working, open the Rock paper scissor simulator in a new tab.)

Comment on the difference your strategic decision-making had on the games' outcomes.
Task 3
Have you ever thought about what result you get when you add two whole numbers together?
What about when you multiply two whole numbers together?
In your workbook or folder, write down what you think happens when adding and multiplying two whole numbers. In particular, think about what the last digit will be.
Use the Random, or Not? activity from the Maths is Fun website below, to guide your thinking and investigation.
Then, answer the big question:
Are the digits 0 to 9 all equally likely?

Activity 2 Task 2
Note: Many of these questions ask for opinion, so you may not have the same answer.
Question 1:
In your opinion, is the Connected to Games infographic:
• visually appealing?
• shareable?
• easy to understand?
Suggested answer:
In my opinion the Connected to Games infographic is somewhat visually appealing and easy to understand. The use of bright colours and colour coding helps me to understand it and draws my attention. However, I found it confusing to know where to start reading as there wasn’t a clear reading path. The infographic has lots of great information and I would share it if someone I knew was looking into games and connection. However, it doesn’t share a compelling insight that I feel eager to share with others.
Question 2:
Which infographic do you find more visually appealing?
Suggested answer:
I find the infographic, The 5 most popular video games in Australia, far more visually appealing than the other infographic. I find it more visually appealing because it is less cluttered and there is a clearer message. The bar graph helps me to understand the data and what is being compared.
Question 3:
Which infographic do you find easier to understand and why?
Suggested answer:
I find the infographic, The 5 most popular video games in Australia, easier to understand because it has the titles of games that I am familiar with. I don’t know all the categories of games that are mentioned in the other infographic so it doesn’t mean as much to me.
Question 4:
Do these infographics convey the same message? Justify your response with information from the infographics.
Suggested answer:
In some ways, these infographics do convey similar messages. The infographic ‘Popular Game Genres’ shows that action and adventure are 2 of the most popular genres of game. Similarly, the other infographic shows that games of this genre, like Fortnite, are the most popular.
Activity 3 Task 3
Question:
Three people each have a tendency to lie 1/3 of the time. There is a coin flip that they all see. They all say it's 'heads'. What's the probability it is actually heads?
Solution:
Each person has a 1/3 chance of telling a lie
Each person has 2/3 chance of telling the truth (1 minus 1/3)
All say heads so everyone is lying OR everyone is telling the truth
The probability that everyone is lying = 1/3 * 1/3 * 1/3 = 1/27
The probability that everyone is telling the truth = 2/3 * 2/3 * 2/3 = 8/27
The probability that it is actually heads = 8/27 divided by (8/27 + 1/27) = 8/9
