### 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...

### Mural Mathematics

By:

Topic(s):

Supporting Resources:

Students will explore existing equity themed murals to identify themes, and the mathematics necessary to plan/create a city mural. Students will utilize Google maps tools to begin connecting Mathematical representations to precisely interpret circle properties and apply them to the mural design.

### 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?

### Percents

By:

Topic(s):

Supporting Resources:

Developed as part of the Math Circles of Inquiry project, this module has students grapple with different representations of percents in various contexts in order to solve real life problems. Students need fluency in percentages for real world applications such as shopping, eating at restaurants, commission based careers, etc. Understanding...

### Rational Numbers

By:

Topic(s):

Supporting Resources:

Developed as part of the Math Circles of Inquiry project, this module is an introductory activity for rational numbers, likely aligned with Grade 7. Students will be given five points on a number line and will be asked to estimate the values of each in a 3-part task and explain...

### Solving Linear Equations: An M&M Mystery

By:

Topic(s):

Supporting Resources:

Developed as part of the Math Circles of Inquiry project, this session is aimed at grades 7 or 8, but may be useful for high school algebra. It consists of worksheets and series of videos meant to get students to develop an understanding of solving linear equations, using the real...

### Trigonometric Ratios in Right Triangles

By:

Topic(s):

Supporting Resources:

Developed as part of the Math Circles of Inquiry project, this five to six day activity is designed to help students understand trigonometric ratios, by building on their understanding of similar triangles and ratios of corresponding sides. The purpose of this module is for students to spend time and energy...

### Systems of Linear Equations

By:

Topic(s):

Supporting Resources:

Developed as part of the Math Circles of Inquiry project, this short module explores a graphical solution to a system of equations. Students answer questions about lemonade sales and physically stand on the coordinates of a giant grid in order to see that plotting two equations on the same set...
