## Hot Dog Duel [3 Act Math Task]

Using Patterns and Linear Relations to Solve Problems In this great 3 Act Math Task shared by Robert Kaplinsky, two well-known competitive hot dog eaters Takeru Kobayashi and Sonya “Black Widow” Thomas star in a Mastercard Paypass commercial demonstrating how quickly you can make purchases when they repeatedly buy and eat hot dogs to outdo each other: http://youtu.be/juTpKsb4zic Stude...

## Cookie Cutter

Solving Problems Involving Area of Composite Figures In this 3 act math task, we will explore the measurement strand of the Ontario mathematics curriculum. Specifically, we will look at the area of composite figures including the area of a rectangle and the area of a circle. Act 1: Introducing the Problem Making Cookie Dough, Rolling Dough and Cookie Cutting In the first act of t...

## Taco Cart

Understanding and Applying the Pythagorean Theorem The Taco Cart is another great 3 Act Math Task by Dan Meyer that asks the perplexing question of which path should each person choose to get to a taco food cart just up the road. While most students could quickly identify the shorter route using basic logic, Meyer throws in a curve-ball when one path forces one person to walk in the sand (...

## Snipping Straws

Solving Equations to Find Radius Given Area of a Circle As Justin Levack (LearnBlended.com) and I were planning for our GECDSB Middle Years Collaborative Inquiry Learning Fair recently, we realized that we were missing a math related activity that could model a simple real world situation and how it relates to mathematics from grade 7 to 9. With both of us learning more each day about serv...

## Thick Stacks

Finding the Equation of a Line Given Two Points This 3 Act Math Task is yet another sequel to the Stacking Paper and Stacking Paper - Sequel 3 Act Math Tasks where we look at linear relations with respect to a real world situation involving packages of paper stacked into a tower. While the original task begins with a direct variation requiring only basic proportional reasoning skills, th...

## The Detention Buy-Out

Solving Linear Systems of Equations Real World Math Problem Learning Goals: After our exploring linear relationships lesson, I will be able to: analyse a real-world situation and make a connection to the prior knowledge I have learned throughout this math course, deconstruct the problem and use prior knowledge to create a solution to the problem, and, show adequate steps to cle...

## Stacking Paper Sequel

Finding the Equation of a Line Given Slope and a Point This 3 Act Math Task is a sequel to the Stacking Paper Real World Math Problem I created a couple weeks back. In the previous task, students were asked "How many stacks of paper will it take to reach the ceiling?" That problem had a sequel that explored the scenario of stacking the paper on a table instead of on the floor in order to see i...

## Gas Guzzler

Proportional Reasoning / Linear Patterning Real World Math Problem This 3 Act Math Task focuses on the rate of change for proportional reasoning / linear patterning / direct variation linear relations problem. Act 1 - Introducing the Task Getting Ready To Gas Up In the first act, students watch a 30 second video that shows someone pre-paying for gas, selecting the grade of fuel and start...

## Stacking Paper

Real World Math in Proportional Reasoning and Linear Relations Here's a new Real World / 3 Act Math Task that is related to proportional reasoning and a direct variation linear relation with a partial variation sequel to boot! Please note that this is part one of three tasks in a series: Stacking Paper - Direct Variation (y-intercept equal to 0) Stacking Paper Sequel - Partial ...

## Bolt

How Fast Is Usain Bolt Running? When introducing slope as a rate of change in my grade 9 academic and applied courses, I used to use a video of Usain Bolt running the 100 m. Fun times, but pretty basic when it came to the question: "how fast is he running?" Dan Meyer manages to provide a video clip that gives us a 300 m race to work with in order to raise the bar slightly, without leaving any...
