Energy Bites! – 3 Act Math

Today I made our go to snack…..peanut butter bites. My kids eat these up like crazy. I turned the making into a math task.

Act 1:

Ask for what they notice and what they wonder?

The intended question here is: How many energy bites will be made?

Have them guess. Too high…too low….best guess.

Ask for what information we would need.

Act 2:

They may notice that the ball is not quite lined up right. How will the adjust?

Is the bite a perfect sphere? Will a sphere be good enough? Give them the volume of a sphere formula. Let them work.

You students may notice the dimensions of the bowl…..or also may notice that its filled up to the 500ml mark. An interesting task will be to calculate the number of bites using either the volume using the dimensions or the volume using the measuring cup.

Act 3: The reveal

Possible sequel question:

What would be the diameter of the giant Peanut Butter Ball if all 22 were mashed together?

And now for the recipe….as requested by Meg Craig!

Updating the MFM1P Spiral

“Have you taught for 25 years? Or have you taught one year 25 times?”

I don’t think I’ve taught the same course the same way ever. Why would we? We don’t have the same kids in front of us. And especially with the resources at our finger tips from our colleagues inside and outside of our schools. I’ve wrote before about the power of #mtbos and it changes the way you teach.

I started spiralling the MFM1P course a few years ago with Kyle Pearce. Since then I’ve taught that course 3 or 4 semesters in row…..and never the same way. New amazing lessons and tools are springing up. For past lessons I wasn’t completely happy with I’ve got to see if this new lesson or that lesson will help my students understand the concepts more deeply.

One change I wanted to make was to include solving equations earlier in the course. In my old plan I waited to introduce it after introducing linear relations. But, after teaching solving equations using the Double Clothesline and the puzzle nature of learning it that way….I can introduce it now and continually practice our skills through warm ups.

If you want to follow along as my day-to-day plan unfolds follow this link! If any of you have been spiralling MFM1P I would love compare notes, or see your plans.

 

 

 

One Best Thing

The MTBoS Blogging initiative has begun! Check out the two options to blog about. 

I choose option 1 which is writing about something good that happened during the day.

Week 1: One Good Thing

Today was a good day! In my mailbox was this little package.

IMG_0408

It’s a package created & designed to make students feel amazing!

It’s from Knowledgehook.

Knowledgehook is an ed tech company specializing in  creating “engagement tools to measure and improve student learning“.

My students have been completing practice questions using their Homework product. An added, amazing bonus is when a student completes a mathalon (completing the majority of questions from the course) Knowledgehook sends in the mail a real (heavy duty) medal. Along with it is a pennant we can hang in the room.

Today a student in my class got that medal! We presented it to him in front of the class. IMG_0411
He looked a tad embarrassed, but I could see he was super proud! Big smiles. Later he told me he was going to wear it home to show mom!

That was today’s good thing.

Reading Relationships – Literacy & Math

Friday last week was a PD day for us here in Chatham. We spent the day going over our OSSLT (Ontario Secondary School Literacy Test) results from last year and discussed how departments can make a difference. We came to a giant conclusion through the data that although OUR students could read…..they struggled with comprehension.

The OSSLT is a giant beast and most schools say “Literacy is a whole school issue.” I agree….but it can seem daunting to take on as a whole. Each of our departments decided to narrow their focus. Departments would choose a type of reading activity and incorporate that type into their lessons on a regular basis. We would own that type of reading assessment and use the data/results in June to see if we made a small difference.

In math we chose reading informational texts and answering multiple choice questions based on those readings.

Here is one sample lesson plan our math department created to do in our grade 9 & 10 classes.

Generate Curiosity

Show students this Estimation180 challenge.

How many pages in this book?

Day 99 http://www.estimation180.com/day-99.html

Have them guess too high, too low, best guess (Grab Andrew’s tracking sheet)

And the answer.

I zoomed into the passage on the answer picture and asked students to read the passage silently to themselves and raise their hand when finished.

We discussed that different people read at different speeds. Students made sure to point out: “Just because I read slower doesn’t mean I understand less.” Connor wanted to go as far as saying that maybe if you read slower you will understand more.

These were great observations and I said let’s explore this more.

I had them guess how fast they read in words per minute. To help make this guess we counted up all the words in the passage above (51) and asked them if they thought it took a minute to read that passage. Some students agreed and predicted they read 50 words/min, some predicted much higher at 300 words/min. They all recorded ther prediction on their whiteboard.

Let’s discover our reading speed! We’ll explore the relationship between words read and the time taken.

Predicting

Using the handout students predict what the relationship between time read and words read will look like.

Finding our Speed

A great reading resource is the series  Critical Reading Series. 

Screen Shot 2015-10-28 at 6.34.54 PMAll articles are of appropriate length with questions that are of the same variety as the OSSLT. The key for us is the book also shows the number of words per article!!

I gave each student an article titled Jackie Chan Actor & Stuntman (1006 words) I also asked them to get out their phones to time how long it takes to read.

After reading, students are to answer questions based on the reading. We’ll take up and compare our score vs. Speed later.

They read, recorded their times and calculated words/min on the handout.

Explore the Relationship.

We used this rate to introduce direct variation. We filled out a table showing words in 1 min, 2 min, etc. We showed it was linear and introduced terms initial value, rate of change, and direct variation.

I stole parts of Kyle Pearce’s template for our task Flaps for this handout

We went on to use our equation to answer the following…

Lastly after students answered the follow up questions from the reading we graphed our reading speed vs. our score on the reading. We’ll repeat this lesson again and again, each time adding to this graph…..trying to see if Connor’s statement — “does reading slower result in better understanding?”  —  true or false.
