## How many Minutes??

A short inquiry investigation today.  We are continuing to use our number sense skills to find answers to real life questions.

Today:

How many DAYS / HOUR / MINUTES / SECONDS will you spend at school this year?

How do you know you calculated correctly?  Show your steps and explanations.

How much time will you spend working on your favourite or least favourite school subject?

What do you need to know from me?

Too Easy??

What percent of the school year will you spend working on your favourite subject?  You could include lunch or recess on this one.

What percent of this year (Sept. 1 2016 to Aug. 31 2017) will you spend at school??

Thanks to Mr. Cameron’s Class for the idea today:

We could compare our numbers.  What might cause some differences?  Why do we have such discrepancies in our own calculations??

Here are some of our solutions from today:

Our thinking is posted on the Padlet below:

## Vex Maze Runner Challenge

A Vex Robotics Challenge:

Navigate the Vex Field by coding your Robot.

1. Your BB Bot must start on the Green mark in the middle (ish) of the field.
2. Translate your BB Bot to three of the four outer green marks.

The winner will complete this course in the shortest amount of time.

You have 3 minutes to look at/take a picture/take a measurement of the field.  You will then return to class with your partner and plan the fastest route.  Discussion and debate is important.  How can you justify and explain which route will be the fastest?

You will be successful if:

• you discuss and collaborate with your partner using clear math vocabulary (specific measures, angles, rotate, reverse etc.).
• Problem Solve
• Persevere
• Communicate solutions
• Have Fun!

## Déchets à Brooke Central

Ici à Brooke Central, je pense que nous avons un problème avec nos déchets.

1. Quelles sont des objets typique jeter au poubelle?
2. Qu’est ce que c’est la durée de vie de ses objets?
3. De tous ces objets; quels objets ont une meilleure destination que la déchetterie?
4. As-tu des solutions possible pour cet problème?

Yesterday we helped to raise some money, not a lot, but every bit counts. We also participated in a global online event that helped to raise awareness. This is not the first time that we have participated in our small yet helpful way. Remember this….

What a first day of school! Congratulations on becoming certified ‘Slacktivists’.

This image was posted to Twitter late last night, but later I found this one

They have yet to release the final tally, but let’s go with this one for now.

Can we explore some of the math that is linked to this great event? If we explore some of the topics that we are now familiar with (percent, ratio, rate, proportional reasoning), can we highlight some of the success of yesterday.

I have a couple of suggestions to start:
1) You could calculate the rate of money raised or interactions per hour/minute/second.
2) You could find what percent of the total money raised was your favourite participating celebrity responsible for (check their original tweet and the subsequent retweets). For example, I quickly searched and calculated that Justin Bieber is responsible for 0% of the money raised…. Shame!
FYI: Unlike me, you need to find someone who actually contributed, sorry.
