1. Math – Each group must complete and submit the correct URL to me for their math app. I will be showcasing them at a conference in Niagara Falls next week. See Isaac or Andrew to learn which link I need. Please make sure it is completely accurate. Check for math errors. Do your best to make it “pretty” as it will be seen by many teachers. Again, triple check your app with a calculator to make sure the math logic is accurate.

If any groups finish, I want you to record a video lesson using something like Explain Everything. In your lesson, describe the relationship between radius and diameter and show an example problem involving finding circumference or area. We are going to use this video to make some augmented reality content so please pay attention to detail.

1. The relationships between radius, diameter circumference and area.
2. The formula for the circumference of a circle.
3. The formula for the area of a circle.
4. How to find the area of irregular polygons which contain circles.
5. How to work backwards – EG: find the diameter when given area or circumference.

If you have been keeping up with the class work, you will be fine.

The two questions below both involve solving problems by working backwards. They came from last year’s Grade 9 Academic EQAO test. We will work on these problems today in small groups during Period 8 when we have math.

Don’t forget we will be having a test next week on 2D Measurement. You should also complete the practice questions at the end of the chapter in the textbook, also posted here:

1. Math – Chapter 5 Mid Chapter Review
2. Science – Spaghetti Bridge Log Book
3. Blog Recount – Recount your Genius Hour experiences – What went well, what didn’t go so well, what is your next step?
4. McGregor “Option” Sheets

I hope you have been keeping up with the homework for Chapter 5 – Circles (2D Measurement). For those who have, today’s key assessment question should be a breeze. It has been posted to our Google Classroom.

Next week we will begin to explore the area of a circle. Have a look at the remainder of chapter 5.

Don’t forget, all sections of the textbook are good practice questions for homework. You may also use the workbook that has been provided as well.
