Talking Two-Way Tables

CC_BY-NC-SA

When analysis of categorical data is concerned with more than one variable, a two-way table (also known as a contingency table) can be used. These tables provide a foundation for statistical inference, where statistical tests question the relationship between the variables based on the data observed. This activity begins to explore statistical inference and testing.

Straighten up and Fly Right!

CC_BY-NC-SA

The purpose of this lesson is to allow the students gather data in a fun way and answer a statistical question through analysis of the data.  Students will fly paper airplanes and analyze the data to determine which style of plane flies longer.

Is the Sine a Circular Function? How about a Star Sine?

CC_BY-NC-SA

Students are often challenged by seeing the conncection between the unit circle and the graph of the sine and cosine functions. This activity is designed to take students out of their comfort zone to experience what the "sine" function would look like if it were based upon other geometric figures.

Paper-folding - Exponential Growth/Percentage Change

CC_BY-NC-SA

In this activity students are posed a simple question, "How tall will a paper be if it is folded 50 times?" and it is used as a fun way to introduce them to the concepts of growth factors, and percentage change.

Here Fishy, Fishy!

CC_BY

Yolanda and Zachary each have some fish. Zachary gives Yolanda some of his fish, and now he has twice as many fish as she does. Students must utilize given information and apply proportional reasoning skills in order to figure out how many fish Zach gave Yolanda.

Steeper, Faster, Division, and Slope

CC_BY-NC

What does "steeper" mean? What does "faster" mean? And how do these ideas connect to the idea of linear functions? This 3-part series explores these questions and helps students to understand why we divide when computing slope and what proportional correspondence has to do with it all!

Sharing Pencils

CC_BY

Sarah and Michelle are working on a class project using colored pencils. Given some information about the number of pencils that Sarah and Michelle had when they started, and how some sharing of pencils has taken place, students must employ proportional reasoning skills to determine how many colored pencils the girls now possess.

Number Systems - Binary, Decimal, and Other systems

CC_BY-NC-SA

Students can struggle mightily with understanding place value as they begin to add and subtract numbers and "carry" and "borrrow". This short activity can be a great way to help students understand the concept of place value.

2015 Excellence in Mathematics Contest

CC_BY-NC

This is the Team Project from the 2015 Junior High Excellence in Mathematics Contest at Chandler-Gilbert Community College. It involves lots of open ended problems from many mathematical areas: Find the weight of a snowman (geometry, proportional reasoning) Find how long it takes ice to form on a lake (rate of change, awkward units) Questions about the amount of mining done in Northern Minnesota (proportional reasoning, conversions) You can use just one part or all parts depending on the audience and the purpose.

Pennies From Heaven

CC_BY-NC-SA

The focus of this activity is to describe the shape of a distribution and to describe the center and spread. Students use data they collect (penny ages) to describe the distribution by its SOCS (Shape, Outlier, Center, Spread).

Earth Day Math

CC_BY

This powerpoint presentation for Earth Day Mathematics Lesson touches on many mathematical concepts such as volume, estimation, mean (average), measurement, and unit conversion. Students work in cooperative groups to find the approximate volume of rubber that a small business has 'rescued' from a local landfill. Alternate application ideas provided.

Nana's Lemonade - Dan Meyer Three Act Task

CC_BY-NC-SA

In a brief video, students are confronted with the situation of a person squeezing a lemon slice into a small cup of water. Then a "big gulp" cup is placed next to the smaller, lemon filled cup. By asking the question, "How many lemon wedges do you need to add for the same lemony taste?" students will begin to experiment and mathematically determine the answer.

Fractions and Free Throws

CC_BY-NC

Do we always add fractions by first finding a common denominator, etc.? Or, could it make sense to add two fractions by adding the numerators and denominators? This activity explores these questions.
