Unit 5. Decimals

Hi kids, we are now starting unit 5, it is about decimal numbers.

I post you here the class notes in English. I also link the unit in Spanish, just in case.

We are going to study this unit in a different way. As you are working on the city in English, I prepared several projects so that you can apply decimal numbers to real life in city. Have a look at this link. I will give you more information in class.


Here you have the extra exercises with their answers. Don't hesitate and ask what you need.

In case you want to go over this topic, have a look at this Decimal numbers page and Units, tenths and hundredths in GeoGebra.

Take care,
