Reinforce properties while solving equations. Learners often ignore properties even as they try to apply them. A well-designed lesson emphasizes the role of additive inverses when solving equations.

We'd all love to have barrels of candy. An interactive shows the steps in evaluating a numerical expression that reflects the cost of buying several different barrels of candy.

Don't freeze out the interactive on inequalities from your lesson plans. Young mathematicians use an interactive thermometer and number line to compare freezing temperatures. Inequalities help express these comparisons.

There's nothing fishy about this resource. A slider interactive lets users adjust the side length of a fish tank cube. It aids in seeing changes in the volume and how to express the volume using an algebraic expression.

Go bananas over a fun interactive! Learners drag a point on a virtual graph of an inequality to see if it is a solution. This helps determine the possible numbers of apples and bananas a shopper can buy with a given amount of money.

Alphabet soup just got an upgrade. Pupils drag expressions from algebraic soup to indicate whether it is a like term to x or to y. Some challenge questions require combining the like terms to simplify expressions.

Not everyone can get what they want in a smoothie. Learners determine the fruit they can place in a smoothie given constraints and preferences. The union and intersection of sets must be taken into consideration.

The learning opportunities with the resource on infinity are finite, but it's still good to use. Individuals investigate the size of the set of integers and the set of even integers. Conclusion: the two sets have the same size.

Get real about learning the real number classification. Young mathematicians create a graphic organizer of the real number system using an interactive. They answer a set of challenge questions on the classifications of real numbers.

If lines aren't parallel or perpendicular, then what are they? An interactive lets users rotate a line to change its orientation with respect to another line. It then indicates whether the lines are parallel, perpendicular, or...

What information can your class determine if they know the number of people attending movie showings? Using the information about the number of people at each screening, learners develop a frequency table. The pupils analyze the type of...

What is a little cake among friends? Given the relationship between the number of cupcakes five friends have, pupils create a bar graph. The learners answer questions about the graph and adjust the graph if one friend shares some of his...

Histograms are likely to give birth to a variety of conclusions. Given the likelihood a woman is to give birth after a certain number of weeks, pupils create a histogram. The scholars use the histogram to analyze the data and answer...

Is it safe to take data at its face value? Pupils use the interactive to evaluate a claim that Virgos are more likely to get into a car crash than others. Individuals determine whether another variable may be at play.

It's just the way the cookie crumbles. Using the data from a class poll, learners create a double bar graph showing favorite cookie types. The pupils compare favorites between boys and girls with the aid of their graphs, then they make...

Explore line graphs and their characteristics through an interactive lesson. Scholars follow a set of directions to plot data on a line graph. They then answer questions about the type of variables, minimum and maximum values, and...

Demonstrate the ease of using a frequency table. An interactive lesson allows learners to create a frequency table efficiently. Challenge questions ask your classes to analyze the data represented in the frequency table. 

What are the advantages to seeing multiple data sets on the same graph? Scholars explore this question as they manipulate the animation within the lesson. Questions within the interactive ask individuals to make comparisons across the...

Introduce the concept of a correlation coefficient using an interactive lesson. Learners begin by manipulating a correlation coefficient and watching a graph change to represent the new value. Questions help strengthen their...

Cameras use histograms to communicate the exposure of a photograph. An interesting lesson uses this idea to help learners deepen their understanding of histograms. It highlights the skew of the graphs by showing under- and overexposed...

 A good lesson doesn't just grow on trees! Help your classes understand the concept of a stem-and-leaf plot using an interactive lesson. Learners first create a stem-and-leaf plot from a set of data by dragging the values to the...

Explore the strengths and weaknesses of box-and-whisker data display. An interactive lesson asks learners to create a box-and-whisker plot from a set of data. Challenge questions focus on determining what types of conclusions they can...

Learning isn't a random process. A well-designed interactive lesson helps classes make key conclusions about stratified random sampling. They calculate group percentages and use those percentages to decide on sampling totals.

Colorado would probably object if Wyoming enlarged its borders. Scholars use an interactive map to change the borders of U.S. states to see how angles change. They then answer questions about regular and irregular polygons.
