Fantastic Friday!
We began the day with Music class.
Today we learned about equivalent ratios during math class. Ratios are used for comparisons. They are used to compare two quantities.
Sometimes it is useful to write a ratio in another way. For example, there are 8 cups of strawberries added to a fruit salad for every 16 cups of other fruits. This is an 8:16 ratio of strawberries to other fruits. However, it can also be represented as 1 :2. So if we add one cup of strawberries we can add two cups of other fruits and keep the same mixture in a smaller amount.

So if we add one cup of strawberries we can add two cups of other fruits and keep the same mixture in a smaller amount.
This is an example of scaling up by a scale factor of 3. The ratio 2 : 3 is the same as the ratio of 6 : 15.
This is an example of scaling down by a scale factor of 5. The ratio 8 to 11 is the same as the ratio 40 : 55.
Here, we scaled up by a factor of 8 to create two equivalent ratios.
We can make a string of equivalent ratios by continuing to scale up or scale down.
1 : 3 = 2 : 6 = 3 : 9 = 4 : 12 = 5 : 15 = 6 : 18 = 7 : 21....
All of these ratios show the same relationship.
Simplifying ratios to the simplest form can be helpful when solving problems that deal with ratios. You can simplify a ratio the same way that you simplify a fraction. This is basically just scaling down until you can no longer scale down anymore.

Ms. Jaskolka gave us questions related to ratios and simplifying ratios as a class and then individually to show our understanding of scaling up and down ratios.
Then we worked in our literature circles for chapter 10 of City of Ember.
After first recess and lunch we had French.
Then we spent the rest of the day working on our slides for our summative project. Students are reminded that only jot notes are required for the slides and that the slides are there to support the information that is being presented and the cue cards will have all the information that will be spoken by the students.
Homework:
1. Read daily
2. Math questions 1-5
3. International Day Research and information due Wednesday
4. Novel study chapter 11
