Powers and roots (radicals)

Posted by ricardogm on 27th September 2018

Howdy!

0. First thing to do: a little history project. Search in the internet to find when and by whom the different sets of numbers were “discovered”. Write the information in a word document and send it to me via email. You have 20 minutes for this task.

1. Some reading about roots. Solve the exercises of the end of the page in your notebook.

2. Same thing with fractional exponents.

3. Well, it’s time for a new thing, and a bit difficult. We are going to learn to rationalize a fraction. Go to this page and try to understand the two (some say three) different cases. Copy in your notebook the theory and try to solve the questions.

5. More rationalizing.

Hi

First day in the computers room:

0. We are going to meet some new tools today (Symbolab, Geogebra, 10 seconds…), to use during the course.

1. First thing, 5 minutes of mental calculations. Use “10 seconds of math” for this purpouse.

2. Try to find out in the internet the name of the man who proved the existence of irrational numbers. Send me an email with this story (my mail is up there ↑ ). Use the email that you are going to use for all the year. You will have to send me lots of work in the following months.

3. Read this page about intervals. Solve the questions at the end of the page.

4. Solve some exercises (2, 3, 10 and 11) about rational numbers. Do it in your notebook and correct them with Symbolab.

5. Some reading about roots. Solve the exercises of the end of the page in your notebook.

6. Same thing with fractional exponents.

Sets of numbers

Posted by ricardogm on 19th September 2018

Hi

Let’s start with a little history:

A little video about sets of numbers. We are going to listen to a part of it, and take notes.

Now another one about intervals:

For you curiosity, here are the first 1000000 decimals of pi
