Solving Systems of Linear Equations


This is a lesson to introduce the idea of solving systems of equations using graphical methods and substitution.  The goal is to help students to make sense of the meaning of the solution to a system and to make sense of what it means to substitute.

Spreading Rumors!

Welcome to Rumor Middle School! News at Rumor Middle School travels quickly! Use the information presented in the problem to determine how many kids will know a rumor an hour and ten minutes after the first person shared it.  Then, find what time it will be when over 4,000 students know the rumor! Stick with it! Use multiple strategies, and be ready to share and defend your work!

SRS vs. Convenience Sample in the Gettysburg Address


Students have an interesting view of what a random sample looks like. They often feel that just closing their eyes and picking “haphazardly” will be enough to achieve randomness. This lesson should remove this misconception. Students will be allowed to pick words with their personal definition of random and then forced to pick a true simple random sample and compare the results.

Steeper, Faster, Division, and Slope


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!

Straighten up and Fly Right!


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.

Sugar Packets - Dan Meyer Three Act Task


The question is simple: How many sugar packets are in a soda bottle? The lesson hooks students immediately with the initial video clip of a man sitting in a restaurant downing packets of sugar one-after-another! The mathematics involved is proportional reasoning.

Talking Two-Way Tables


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.

The Forest Problem


Students want to know why they would ever use a sampling method other than a simple random sample. This lesson visually illustrates the effect of using a simple random sample (SRS) vs. a stratified random sample. Students will create a SRS from a population of apple trees and use the mean of the SRS to estimate the mean yield of the trees. Students will then create a stratified random sample from the same population to again estimate the yield of the trees. The use of the stratified random sample is to control for a known source of variation in the yield of the crop, a nearby forest.

Thinking About Exponents


The idea of negative exponents and zero as an exponent is a problem that persists with students into a college calculus class. What is, for example, 2-4 and why? This activity is designed to help students to make sense of exponents from a real-world context.  By the way, I plan to follow this up with an extension including rational exponents like 21/2.
