One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

High schoolers organize data from the USA TODAY Snapshot, "Is leisure time really shrinking?" into two scatter plots and determine the quadratic model for each scatter plot. They determine if these graphs intersect and learn the concept...

Learners analyze linear functions in this algebra instructional activity. They explore the meaning of slope and the slope-intercept form of a line as they investigate the effect changing parameters on the graph of a linear function.

Learners use their graphing calculators to view graphs of equations. They tell if each equations is or is not a function and are shown pre-set graphs on their graphing calculators. They use the Quick Poll feature to indicate if the graph...

Engage in a instructional activity that is about the use of statistics to examine the number of school buses used in particular states. They perform the research and record the data on the appropriate type of graph. Then they solve...

Pupils investigate financial applications of mathematics in this mathematics lesson. They will investigate equations that represent a company’s income, expense, and profit functions and use those equations to identify break even points...

Explore graphical representation of a real-life data set and determine the exponential regression model for the data in your classroom. Young scholars also compare the estimated value to the given value by determining the percent error.

Students collect and analyze data based on academic performance. In this statistics lesson plan, students create graphs and analyze the data they created. They use positive, negative and no correlation to analyze the data.

Young scholars use technology tools and resources for managing and communicating personal/professional information. They select and apply technology tools for research, information analysis, problem solving, and decision making in...

Pupils collect data from tossing a ball into the air. Using a data collection device, they graph the data, set a window, and analyze the height of the toss, how long the ball was in the air, etc. They then find an equation that models...

Students write equations of a line. In this algebra lesson plan, students investigate the assassination of JFK through linear equations. They calculate the length of given line segments.
