3 Act Math Investigations!

We are loving the 3 Act (or 4 Act) lesson investigations in math.  They start with a “trailer video” that the students watch first.  They generate a number of possible math questions that could go with the video.  This really gets them thinking about math in the real world and situation where they might use math.  It also activates prior knowledge they have.
Next we watch Act 2 which provides some more information and a problem to solve.  The students solve the problem, present their solutions and then we watch Act 3.
Here is the first one we did.  It was created by Kyle Pearce @mathletepearce at Tap Into Teen Minds
Cookie Cutter
Act 1
The students came up with many excellent questions including the questions we were going for:  How many more cookies can we make?
Act 2
Here is some video of two of my students sharing their solution.  I started to use the time-lapse feature on my iPhone and we found it is too fast.  I’ve downloaded an App now that I hope will be better for next time.
Finally, we watch Act 3
We had some discussion about why Kyle Pearce was able to get more cookies than we calculated.  What do you think?
I started blogging for this class on Evernote and but I found it didn’t have the features I need so I’m continuing on here.  If you want to see the first few lessons leading up to this check them out here.  They give some background on Pi, deriving the formula for the area of a circle and Mindset.

iPads! & A Math test this Thursday!

On Friday we got to play with our new iPads. They were purchased through a special funding program that I applied for last year. We will be using the iPads to support our math learning and to create multi-media presentations. Watch for more coming up!

On Thursday we starte to learn how to use FRAMES, a stop-motion software program for digital story telling. We will be creating our own animations of stories in the near future, once we learn how to use the program. For more information about the program follow this link to Tech4Learning.

There will be a math test this Thursday for both grades.

The students have been given a test outline. We will review in class and they will get take home review questions that are modeled from the test tomorrow.

Here are the outlines:

Infer, Infer, Infer……and Measure

We are doing some more inferring this week!  We read a story from the 2011 EQAO test and answered the questions.  Many of the multiple choice questions require inferring.  All of the written questions do.  When we infer we use evidence from the text and our background knowledge.  The story we read and the quesions 1-6 can be found here and a scoring guide can be found here.  If you look at the scoring guide you will notice that the answers include evidence from the text and the student’s own thoughts (background knowledge).

Over the next few weeks, we are going to be looking at inferring theme and the meaning of language – new words, metaphor, figurative language and idioms. 


Mr. B, our student teacher, is back and he wil lbe teaching a unit on measurement, specifically linear measurement, area and perimeter.  Grade 5s will be studying the perimeter and area of triangles and grade 6s will look at quadrilaterals and paralellograms.  Today he read the class a story called Spaghetti and Meatballs for All by Marilyn Burns ( a Math guru!).  In this book Mr. & Mrs. Comfort hold a dinner party for 32 relatives.  Mrs. Comfort has figured out how to arrange their rental tables to seat everyone but Mr. Comfort and other families keep rearranging the tables as they arrive.   Of course, they can’t all fit at the table as they get pushed together as they lose at least two seats every time.  Eventually, they end up with the original configuration that Mrs. Comfort carefully thought out.   The students’ activity was to find as many possible table arangements for 20 people and to compare the area and perimeter.    The students used square colour tiles to model the arrangements.  Alas, I forgot to take photos today 😦

The big idea behind this lesson is that the area can remain the same and the perimeter can change or vice versa, the perimeter can remain the same while the area changes as in the story where they only had 8 square table to use so the area was alway 8 tables squared.
