Solving equations – #hfi78

A quick review video if you are having difficulties.

Practice, Practice, Practice…..

SolveMe Mobiles – Great for practicing the idea of balancing an equation.

Algebra Touch App – Great app to practice solving algebraic expression and equations. Combine Like terms, simplify, eliminate, factoring are all reinforced – $3.99 though!

Bell Let’s Talk Math:

Each Social media interaction with #bellletstalk generates a 5 cent donation from Bell.

Can you create an algebraic expression for anyone’s Tweet and their retweets?

What would happen if they made a $500 donation along with their tweet?

Here is an example:

Could you write an algebraic expression for Prime Minister Trudeau’s tweet?

How much money would this tweet generate? Use your expression to solve.

Can you find another example for solve?

How about this tweet? What might be the expression here?

How much will Em have to donate? How much will she raise in total?

This is a nice little play on words. How much $$ did it raise?

How about this one?

Coding a Simulation

Let’s explore some more ideas about probability….

Can we test this law using some coding?

ummmm….. probably?

Head on over to Scratch or Snap (if you want use your iPad)

You are going to try and design a coin flipper…. here are some helpful images.Screen Shot 2016-06-07 at 10.36.49 AM

You will need to design some costumes to allow your coin to change from heads to tails.

Let’s get started and see where we end up.

We will be exploring the idea that experimental probability will eventually meet the theoretical probability.

Here is the code for a turbo flip option:

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.
  3. Return to the starting position.

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!

(Fail) + (Try Again) = First Attempt in Real Learning 

 

 

 

No Coffee Mo Problems!

Mr. Hewett has been without coffee for 5 days!!!!

It is of course for a good cause:

Our Class Blog: http://ourh2ochallenge.blogspot.ca/

Let’s track how much Mr. Hewett has already saved for the Water Project.

Here are some details to help you out.  Max and I wake up early (5ish), I usually enjoy a cup of coffee while Max enjoys an episode of Curious George (I also enjoy Curious George). I drink one Tassimo Disc worth of coffee at home, purchased from the Sobey’s in Grand Bend (usually).

Once I arrive at school I will typically drink one to two more cups of coffee and on the weekends I generally have one or two medium coffees from Tim Hortons.

How much coffee savings can you calculate for the week?  How much money should Mr. Hewett donate at the end of the Water Challenge?

Do you need any more information? Just ask.

More Fractions!

I have been mining the twitterverse looking for helpful images/tricks of fractions.  Hopefully some will get you thinking or help you better understand a concept.  Check them out.

trick for adding/subtracting
Yum!

Can you solve the following Lego problems?

use the legend above to help solve

Task:

1.Think of your favourite food

2. Find a recipe (with at least 3-5 fractions in it) and take a screenshot.

3. Copy into explain everything.

4. Suppose you had to triple the recipe, what would the new quantities be for each ingredient?

5. What if you had to divide the recipe in half?

6. Try your best to show your thinking, remember that you can always add an oral explanation to enhance your communication.

UPDATE!

Mixed and Improper Fractions practice (may not work with ipads)

Dividing Fractions:

Multiplying Fractions is rather easy to do…. but you will need to be comfortable with reducing your answers.

Final Task!

Create a 20 second stop-motion video demonstrating your understanding of one of the fractional concepts that we have covered in the last week.

Feel free to use; Legos, Pattern Blocks, Food or something else.  Be creative and have fun while you learn, after all that’s the point.
