### Central Public School

Great learning with you all again today. Please find some resources below:

## The Progression of Fractions

Exploring Fraction Constructs and Proportional Reasoning Fractions are a beast of a concept that causes struggles for many adults and students alike. While we all come to school with some intuition to help us with thinking fractionally and proportionally, the complexity quickly begins to increase as we move from concrete, to visual, to symbolic and from identifying, to comparing, to manipulatin...

## Gimme A Break [3 Act Math Task]

### How many pieces of the whole are there?

Adding/Subtracting and an Intro to Multiplying/Dividing Fractions A colleague and good friend, Dave Burke, reached out to me recently for some ideas around adding and subtracting fractions. In particular, he was interested in trying to make the topic a little more enjoyable by adding some context. This was a challenge I was really eager to work on because working with fractions is such ...

## Doritos Roulette: Hot or Not? [3 Act Math Task]

### How Many Chips Are Hot?

Don't Get Burned By Doritos Roulette Spicy Hot Chips! Today, I was finally able to record some footage involving the mysterious Doritos Roulette chips when I was working with some colleagues from Tecumseh Vista Academy. If you haven't heard of the new Doritos flavour, here is the commercial: https://youtu.be/MJTr39UJlAs Special thanks to: Joey Demarse, Dan Frezell, Diane Gardin, Craig Gu...

Looking forward to working with you again in the next couple weeks!

## Friday April 21st, 2017 – Intermediate PLC

### Central Public School

The big topics coming up for the Central Public School Intermediate group involved measurement including area, surface area and volume.

Here are some tasks that we explored:

## R2D2 Post-Its by @MrOrr_geek [3 Act Math Task]

### How many post-it notes will it take to fill the board?

Applying Area to Proportional Reasoning Thus far in the spiral, I haven't made it to measurement yet. Today, we're going to touch on area and lead us into an exploration of area formulas over the next day or so. Jon Orr's R2D2 Post-It Notes 3 Act Math Challenge is a nice low floor task that works with area of a rectangle and proportional reasoning. Here's the Act 1 video we show the student...

## Mowing the Lawn [3 Act Math Task]

### How long will it take to mow the lawn?

Real World Mathematics Using Proportional Reasoning, Linear Equations & Measurement In the Mowing the Lawn task, students will have an opportunity to utilize skills related to proportional reasoning, linear equations, and measurement after watching the information Mr. Pearce collected while mowing his lawn. This activity is geared for his grade 9 applied class, however it can be modified t...

## File Cabinet by Andrew Stadel

We then discussed how one might go about doing something “sticky-like” for surface area in their classroom. We came up with the idea of having students cover something (cereal box, their desk, etc.) with square pieces of paper, say 4 cm by 4 cm. Then, give them a piece of 8 cm by 8 cm paper and have them discuss with their partners how many they’d need to cover the same object. Is there a relationship?

If I double the dimensions of my square piece of paper, does that double the area?

We could do more explorations with tripling the area, etc.

We didn’t get to Prisms Vs. Pyramids, but thought I’d add this here for Tammy as she was absent and may want to explore a bit more deeply into volume with her grade 8 students:

## Prisms and Pyramids [3 Act Math Task]

### How many pyramids does it take to fill the prism?

How Many Pyramids Does It Take To Fill a Prism? In this multi-step 3 act math task, the teacher will show three sets of 3 Act Math Style tasks involving comparisons between rectangular prisms and pyramids, triangular base prisms and pyramids, and cylinders and cones. While the intention has been to leave Act 1 of each set very vague to allow for students to take the problem in other direct...
