Solving systems by substitution can be a challenging topic in algebra I. Here is a lesson that builds on students' understanding of intercepts to begin the process of substitution, and all work is reinforced graphically to build...

Get the class batty over graphing. Young mathematicians plot ordered pairs in all quadrants of a Cartesian plane, and connect the points to create a bat.

In the second lesson of a five-part series, young climatologists use provided temperature and precipitation data to create climographs of three different cities. They then analyze these climographs to develop a general understanding...

Learn how to slide sine back and forth and up and down. Pupils move the starting point of a graph of sine vertically and horizontally. They investigate the changes to the equation of the graph in relationship to the translation. They...

Discover another way to interpret multiplication. Using an interactive, learners slide points (representing the factors of multiplication) along the x-axis of the graph of y = x^2 and observe changes in the line segment connecting the...

Develop the problem solving skills of your young learners with this collection of math newsletters. Covering a variety of topics ranging from simple arithmetic and number sense to symmetry and graphing, these...

What does solving an inequality have in common with solving an equation? Almost everything! A math resource focuses on the one exception. The examples lead learners through the steps of solving an equality when multiplying or...

It is positive that how one performs on the first test relates to their performance on the second test. The three-question assessment has class members read and analyze a scatter plot of test scores. They must determine whether...

The coordinate plane is a popular place! Identify rotations, reflections, and dilations on the coordinate plane. Pupils work in small groups to match transformations of a figure with the description of the transformation....

What does dropping a ball look like as a graph? An engaging activity asks learners to record a video of dropping a ball and uploading the video to software for analysis. They compare the position of the ball to time and calculate the...

Explore the link between solar energy and cloud cover using real data from NASA from China! Future climatologists analyze and interpret graphs of solar energy on clear and cloudy days using a literacy cube. Investigators draw conclusions...

Go around and around on the complex plane. The sixth lesson in a 23-part unit reviews representing numbers in the complex plane. Pupils graph numbers with equal moduli and notice they represent a circle. They continue to explore complex...

It's important to have the correct number of flower arrangements at a wedding. Scholars match an inequality and a graph given a situation involving roses for wedding receptions. A set of challenge questions checks the matching pairs.

Not everything that's one-sided is bad. A slider interactive aids learners in investigating one-sided limits from graphs. A set of challenge questions assesses their understanding of the relationship between one- and two-sided limits.

Who said teaching a STEM lesson had to be challenging? Incorporate a career and technology-centered car build into your upcoming force lesson plan, and your class will be moving down the road in no time! Pupils practice...

Predict outcomes using linear models. Young mathematicians strengthen their understanding of slope and linear models using a hands-on activity. They monitor the dissolving rate of bouillon cubes, graph their data, and make predictions...

Put it in your own words. Scholars complete a mini instructional activity about paraphrasing then complete a note catcher using the text A Limited Supply. They continue studying Canada's natural resources by analyzing the graph...

Learners use the on-line affine recurrence plotter to graph equations. They work on-line to create graphs of trout in a trout pond and savings account balances when interest is compounded over time. Links to the four one-day lessons are...

A new, improved version of the game Battleship? Learners graph linear inequalities on the coordinate plane, then participate in a game where they have to guess coordinate points based on the solution to a system of linear...

It all starts with arithmetic. An educational resource provides four items to use in summative assessments. The items reflect the basic skill level required by the standards in the domain and are designed to have...

Examine the connection between rational functions and their graphs. Individuals use an online manipulative to sort equations with horizontal and oblique asymptotes. They focus on the degree of the numerator and denominator.

Create a shift in TV viewing habits. The interactive presents a cosine model of an individual's TV viewing habits during a year. Class members move the model to reflect given conditions. Finally, they determine key features from the...

Change the y-intercept by adding a constant to the function. Individuals move three functions vertically along the y-axis. As they observe how the equation of the functions change with the vertical movement, learners determine how...

Learners graph and order numbers using a number line. They also solve word problems using fractions and decimals and rewrite equations to solve problems correctly. Several example word problems are given.
