Real Misleading Graphs

A line is a line is a line. As a middle school assessment task, learners first identify graphs of given linear equations. They then identify the equations that represent real-world situations.

How do letters and numbers create a picture? Scholars learn to create input/output tables to graph functions. They graph both linear and nonlinear functions by creating tables and plotting points. 

Seeing functions in nature is a beautiful part of mathematics by analyzing the motion of a dolphin over time. Then take a look at the value of a stock and maximize the profit of a new toy. Explore the application of quadratics by...

How high is too high for a belly flop? Learners analyze data to model the world record belly flop using a quadratic equation. They create a graph and analyze the key features and apply them to the context of the video.

Use context to explain the importance of the key features of a graph. When context is introduced, the domain and range have meaning, which enhances understanding. Pupils use application questions to explore the key features of the graph...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

Sometimes a graph makes situations much easier to see. After learning about discrete and continuous graphs by watching a short video, scholars match graphs to real-world situations. The provided graphs are a discrete linear graph, a...

Parameters can move and change the steepness of a graph. Introduce the effects of changing the slope or the y-intercept of a linear graph. The resource shows how to incorporate changes on graphs and how they will move up, move down,...

How many yellow Skittles® come in a fun-size package? Use candy color data to construct a bar graph and a pie chart. Pupils analyze bar graphs of real-life data on the Texas and Massachusetts populations. As an assessment at the end...

There are many ways to solve a quadratic equation. Let's check out how to solve a quadratic equation by graphing. But first, let's find the axis of symmetry and the vertex before making a table of values. Write the values as ordered...
