These are similar to the Coin Problems, but are chart should
only have two columns, Now and Then. Your Equation will
usually come out of One of the Then cells. Add or subtract years
depending on if Then is the future or the past. In the second sentence
they usually also give you another comparison, like twice the age.
Put an equal after the first change, (+ or - years) and the new comparison.

Intro to Algebra

We will now start learning about Algebra.
Algebra can be thought of as looking for
unknown numbers (sometimes called variables).
The unknown numbers are usually written as
a letter. The letter stands for a number we are
looking for. So for example 3+x=5 means
we are looking for the number that would
make the equation true. so we know that
2 = x would make it true. Let's watch a video
that introduces how we solve more questions like
this. https://youtu.be/rBf1eYwwQFE

Creating a Budget

Use Excel (or Google Docs Spreadsheet) to create a expense budget for a trip to Medice Hat.

Remember that you must start calculations in excel with the = sign.

Here are the information sheet and an example of how you should set up your Spread Sheet.

For more information on entering calculations into Excel watch the following tutorial.

Elections Math

We are going to look at the results of the last three elections and compare "Popular Vote" (percentage of the voters that voted for each party) to the proportion of the seats each party won in the House of
Commons.

Find the number of eligable voters in this election, as well as in the 2008 and 2011 elections. Then find out how many people actually voted in each election. What % of people voted? What percentage of these voters voted for each party? How many seats were there available in the House of Commons in each election? How many seats did each of the top 5 parties win? What percentage of seats did they win? Why is there a difference between this percentage and the Popular vote?

 

 

Most of this information can be found at election.ca including past elections (under the Main Website tab)
