10_4 Homework

Homework - due Friday 4 Dec

The idea of this homework was to explore how equations can be manipulated while still maintaining balance.  Some excellent examples of the homework below.

Some of the issues that came up in this homework was:

• Not checking work - You should check that the equation is actually equal.
• Subtracting or adding numbers that were multiplied to other numbers
• Dividing by numbers when there are more than one term on that side of the equation

 Rochelle

Create your own example of the web above, either using the equation:

25 - 4 x 3 = 13 

or come up with your own equation.  Show at least 5 different ways to represent the relationship between the numbers.

 Examples of the homework showing working and useful ways of thinking about the technique

 We all make mistakes.  It's essential to learning.  It's good to show the mistakes and how you corrected them.

Produce an infographic

Choose a topic of your choice that has some statistics or numerical information.
Produce:

1. a dual or composite bar chart
2. a pie chart (comparative pie chart if you are adventurous!)
3. one other form of visual data representation (pictograms, bubble charts, stem and leaf, something else new)
4. a title
5. an appropriate image
6. a small piece of written text about the topic

You can complete this in your book, on paper or electronically. Research the term infographic and look at a few examples before beginning.

9.2 Grouped Data Homework

Comments on grouped data homework - submitted 14 Nov

Feel free to leave comments here about the homework and how it can be improved

Well set out

What would a sensible value for the mean be?

Why is 45,450 unlikely to be the mean?











Very good example of how to set out work clearly...
...but there are a few problems

Where are the errors?
Why do you think it has been ticked?
What do you think about the size of the groups?

How would we know this was a mistake?

What could you do in this case?

It can be difficult to check all of the numbers that you've tallied.  How could you make it easier to check them?

Colour coding?  More strict methods of tallying?  What else?

Is the mean 178.08?

Start with good intentions...

 A mean of 5.92 miles??
And it's ticked

A lot of effort has gone in to this homework plus evidence of checking and a sensible mean with the calculation shown.

Very clear.  An excellent example of a piece of homework!
