In Grade 10 we continued with some more challenging substitution problems.  We then had time to practice our skills using a “speed dating” activity.

We worked with partners across the table, solved the problem, then one set of partners shifted so they could try the problem with the support of the “expert” who stayed put.  The next round, the former “expert” shifted to a new question, and new partner (who had just become an expert).
We are solving by substitution, elimination and graphing now.  We are also working on making good choices to solve problems efficiently.

Today in Grade 9 we mastered the Brightspace Portfolio app, and also learned how to submit an assignment online using MindsOnline (D2L).

We will be submitting assignments every 2 weeks, and also emailing home to share our learning with our families.  Your first assignment is posted!  Finish it tonight for homework please.

We went to the park today.

And had a great time all afternoon.  We learned a cheer, and got very spirited.

We learned all about the clubs at KC after we got back.  These are a few…there must have been 30 different options!

We met Emma Jane, and learned some stretches to help us relax.  We also talked about deep breathing, and how our thoughts, feelings and behaviours are connected.

We also (after being completely relaxed) started graphing our multiplication results.  We are making a scatter plot and talking about the trends we see.

We are also going to see if we can extrapolate to predict how we’ll do next Monday (using our graph trends).  
Remember that tomorrow is grade 9 fun day in the park, so we will have our next math class on Wednesday where we will tie up loose ends with the graphing, the quiz, the portfolios and write our emails that were omitted on Friday.

We worked with plastic snap together shapes to build prisms.  We know prisms have 2 identical bases and if you slice it parallel to the base the slices will be identical.

We unfolded the prisms and worked on calculating surface area.  

Last night we measured our TV screens, and today we looked at the results.

We tabulated the results on “desmos” to have a look at the collection of results in our scatter plot.
Period B’s results showed the following relationship.  We calculated that the ratio in the data was about 3:4 or 9:12 which was not what most of us predicted. (The current TV proportions are frequently 9:16).  We discussed vocabulary to describe the trend, and discussed some “outlier” points and where the variability may come in our measurements (measurement error, how to report fractions of inches, age of TV-older TVs could be more square).

Here’s period C’s results.

With more data, we were able to see a similar trend, but one that was more close to the predicted 9:16 ratio.

After looking at TV data we added circles to our skills of area/perimeter calculations.

As promised, Pythagorean theorem was hidden in this question!

We saw some interesting approaches, and learned a lot from others in our group, and also from other groups.

When we work at the wall it’s easy to show others our plan.

We need to work on careful communication so our work is easily followed by others.  Sometimes arrows are a really helpful thing!

Today grade 9s worked on remembering a lot about area and perimeter calculations for complex shapes.  

This particular question could be worked in a few ways.  Some saw a big rectangle with a square and triangle removed, while others broke it into rectangles and triangles.

We saw another approach involves a trapezoid (and our new favourite song…to the tune of Frère Jacques)

L’aire d’un trapèze, l’aire d’un trapèze

Base plus base, base plus base

Divisée par deux, divisée par deux

Fois hauteur, fois hauteur.

To calculate the perimeter we needed to figure out the missing side length, which caused many people to try to remember that triangle thing (a.k.a. Pythagorean theorem).

To help remind us of how it works we watched a video

We’re going home to measure TV screens tonight (which are all sold based on their diagonal length).  We’ll tabulate results tomorrow.

Good work again grade 9s.

Today Emma Jane came to talk to the grade 10s.  She talked about her role as adolescent care worker (ACW).  She’s here to help with issues at school or at home, with friends/family/mental health etc.  She has a service dog in training with her, so we also learned a bit about service dogs, and that we need to not interact with them when they have their vest on (because they are working and shouldn’t be distracted).

We talked about the progressive muscle relaxation (in the poster) and the stretches that go with each word.

We talked about strategies to reduce stress and anxiety including deep breathing, thought stopping, and mindfulness.  We also discussed keeping time for self care in our busy schedules so we don’t get overwhelmed!  

Nous allons prendre les photos de notre travail en classe pour nos portfolios de mathématiques ce semestre.  Nous allons apprendre comment utiliser Brightspace Portfolio (une application qui est reliée à D2L–un façon d’avoir un cours à l’internet).

Voici les étapes:

1.Télécharger l’application “brightspace portfolio” 

2.Si vous utilisez votre téléphone/ordinateur/ipad choisissez “my device”, si vous utilisez un ipad/ordinateur de quelqu’un d’autre/l’école, choisissez “shared device”.

3. Chaque classe a un QR code (notez bien que immersion/extended sont les cours différents selon notre application).  Utilisez le QR de notre classe.

4. Chaque individuelle a un QR code aussi.  Vous allez recevoir une carte avec votre QR code en classe.

5. Vous allez prendre les images de votre travail, et vous allez écrire un petit peu à propos des images.  Les vendredis, nous allons utiliser les images dans nos portfolios pour accompagner ce que nous écrivons.

6. D2L est un program utilisé par Limestone pour avoir les classes à l’internet.  Vous allez sur le site web de limestone, et en bas choisissez “minds online”.

7.Mettez votre login et mot-de-passe et ensuite vous allez voir un page avec les classes à droite.  Notre classe est MPM1D3/4.  Vous pouvez regarder là pour voir “content” et les autres choses.

8. Pour voir le portfolio, regarder en haut à la droite pour votre nom.  Selectionnez cela et vous allez voir un option pour portfolio.

9. Avec D2L des fois on va avoir les petits projets à faire (nous allons essayer de faire les courriels d’ici, et aussi nous allons remettre digitalement les projets).

Today we looked at problem solving.  After examining the tug of war, we used the 3 act “technology weigh in” task to practice our skills.

Here’s the technology weigh in video.  Here’s the answer video too.

We had some productive struggle as we worked through this one!

We’ll keep working on these problem solving skills this week.
