### Hungry for Change: Food Deserts in CT

By:

Topic(s):

Supporting Resources:

In this lesson, we are tasked with determining a location for a new supermarket to address a possible “food desert” problem in Glastonbury. You will use these diagram to guide your analysis along with tools in Desmos and Geogebra. To qualify as “low access” in urban areas, at least 500...

### Racial Profiling

By:

Topic(s):

Supporting Resources:

To investigate situations in the real world, we sometimes create a mathematical model. A mathematical model is a simplified version of the real world that allows us to understand the real world a little better. Over time we can change this model so that it gets closer and closer to...

### Modeling a Pandemic

By:

Topic(s):

Supporting Resources:

How can mathematics help us understand the phenomenon of a pandemic? What factors impact the spread of a disease like Covid-19? Which of these factors can we influence? (society, in schools) How can mathematics help us act during a pandemic toward better outcomes?

### Fold & Cut

By:

Topic(s):

Supporting Resources:

What shapes can result from the following fold-and-cut process?
Take a piece of paper.
Fold it flat.
Make one complete straight cut.
Unfold the pieces.
Are all shapes possible?

### Cup Stacking

By:

Topic(s):

Supporting Resources:

Begin with a row of cups and end with all of the cups in a single stack. Rules: 1. Count the number of cups in a stack. That stack must jump that number of spaces. For example, 1 cup can only move 1 space; 2 cups have to move 2...

### Liar’s Bingo

By:

Topic(s):

Supporting Resources:

From recognizing a pattern to generating terms, to abstracting and making inferences, tasks based on patterns embody the “low-threshold, high-ceiling” trait of good problems. Liar’s Bingo is all about patterns. This session involves recognizing patterns and searching for underlying structure, number theory, numeration, and potentially binary arithmetic. Sometimes, as in...

### Locked Out: A Breakout Box Session for Your Circle

By:

Topic(s):

Supporting Resources:

Escape Rooms and “Bomb Disposal” activities are growing in popularity as a form of team building and entertainment. This session blends the two ideas to create a cooperative math activity where the challenge is to solve math problems whose solutions generate combinations to open a locked box. The math problems...

### Mathemagical Card Tricks

By:

Topic(s):

Supporting Resources:

There are many card tricks based on simple mathematics as opposed to sleight of hand. In this session, participants will play with a number of such tricks, test them out and work on discovering the math underneath, with a goal to formalize the mathematics that makes the trick work.

### Piece of Cake; Delectable Fractions and Decimals

By:

Topic(s):

Supporting Resources:

While exploring the relationship between fractions and decimals, participants will have the opportunity to practice operations with fractions, notice and explain patterns, review understandings of place value and number sense, and justify their reasoning. You can get a taste of math research by repeating these two steps: Think about an...
