We were looking at how to prove a point (3,5) is the intersection of two given lines y=x+2 and y=-2x+11.

Some solved the system by substitution

Some substituted x and calculated y for each line

Some made tables of values for the lines and checked if (3,5) was on both lines

Some substituted x and y and verified that the two sides remained equal

Some solved by graphing
It’s pretty awesome to have so many ways to approach a question!  Many thanks to those who explained their work today.

Grade 10s, you are working hard to review all of the grade 9 course work.  Here are some resources for you to look at (en français of course)

Graphing lines

Translating words to algebra

We had a look at an interesting app/website that can help us with graphing scatter plots and also equations.  It’s free, and pretty easy to use.  Download it and give it a try!

We are stacking cheerios today!

We are comparing the stacking rates

And making graphs

Here are the worksheets we used: grade 9 and grade 10

After we determined who stacked cheerios the fastest and the slowest, we set up a head to head competition, and we levelled the playing field, giving the slower person a head start (we calculated how many cheerios they’d need to have as a head start–initial value).

Hello grade 10s, here is the worksheet we are using today.

Grade 9s, here’s yours.

Grade 9s you will be getting textbooks tomorrow.

Hi Grade 9s,

It’s been kinda crazy with two snow days in a row.  EQAO has been moved to Thursday and Friday, and with our chapter 5/6 test (I’ll make it a small one) on Monday, we will have only 2 days in class to review.  I have made this checklist to help you get started on your studying tonight and this weekend.

Dear Grade 10s, Here’s a checklist of all you need to know for the exam.  It’s been rough with 2 snow days in a row.  I hope you are working hard.  We will have our test Thursday and Investigation Friday in class time.

We made it to holidays!  Have a safe and happy break.  Remember exams come quickly when we get back.

A class tradition has become having a secret santa gift exchange before holidays.  The emphasis is on making our gifts.  This year there were some very creative presentations, songs, and artwork, baked goods, and inside jokes.  Many thanks to everyone for all the efforts and enthusiasm you brought to this tradition.

We made cookie houses this week and calculated the volume and surface area.

We also worked on making an icing recipe that would stick the houses together well.  We needed to adjust the proportions of sugar and water until it was just right.

Then we added the candy!
