Stamps come in sheets, strips, and singles. Young mathematicians use their knowledge of hundreds, tens, and ones to determine how many stamps Mike has altogether.

Introducing ... the Transmographer. Young mathematicians investigate translations, reflections, and rotations. The applet lets users perform transformations on triangles, squares, and parallelograms.

No graphing calculator? No worries, there's an app for that! Young mathematicians use an app to graph functions. In addition, they can also plot data points.

Solve your equation and prove it, too. Young mathematicians solve linear equations using an interactive. They must input a property to justify each step of their solutions.

How does life evolve? The interactive provides a simulation based on the Game of Life invented by mathematician John Conway. Users can run the applet with the preset rules and settings or adjust them to view whether overpopulation or...

Are your young mathematicians having a hard time making heads or tails of probabilities? It's no toss up—here is a resource that's sure to straighten them out! Learners run the interactive to toss a coin a different number of times....

Teach budding mathematicians how to square a triangle with an interactive that shows a graphical proof of the Pythagorean Theorem. Pupils alter the lengths of the legs using sliders. Using the inputted lengths, the applet displays the...

How long is your hand span? Young mathematicians measure their hand span from pinky tip to thumb tip using a centimeter ruler. After rounding to the nearest whole centimeter, learners plot their data on a line plot.

Need a quick review for greater than or less than? Young mathematicians use <, >, or =  to complete a set of seven comparison number sentences.

It's Valentine's Day in geometry class! Celebrate the day of love with a heart-themed activity in which young mathematicians create a cardioid on polar graph paper.

This Valentine's Day, add a touch of festive flair to your math lesson with a booklet that combines counting, reading, and a sweet treat. Young mathematicians read a poem, count candy hearts, and record the amount of each color found. 

Get the most Valentine's candy for your money with a fun math activity! After examining three deals for buying candy hearts in bulk, young mathematicians decide which deal is the best and use bar graphs to demonstrate their claim. They...

Inventor, astronomer, surveyor, mathematician, clock maker. Learners celebrate the life of Benjamin Banneker by building creative analog clocks, making scale models, and solving problems related to surveying. The activities model the...

No luck required here! A St. Patrick's Day-themed missing-factor presentation prompts young mathematicians to read a multiplication problem and select the answer to complete the equation. Clicking on the correct answer allows players to...

Your classroom will overflow with learning as they analyze the volume in a pot of meatballs. Young mathematicians predict the number of meatballs that will make a pot of sauce overflow. They incorporate both the volume of cylinders and...

Take the resource out of the file cabinet. Young mathematicians estimate the number of sticky notes it would take to cover the surface area of a file cabinet. They answer a set of questions on how the number of sticky notes would change...

Drawing the perfect circle is harder than one would think! What makes a circle a circle and how can you define that with a formula? Young mathematicians devise their own methods of analyzing the imperfections of circle drawings. Using...

Read between the lines to find a solution. Budding mathematicians analyze a situation to solve a problem. They view a video presentation of the problem, brainstorm important information to gather, and write linear equations to find...

Keep your classes climbing in the right direction. Young mathematicians collect data from a video presentation. Using their data, they build an arithmetic sequence and use it to make predictions.

Get your classes on their way to extreme couponing! Young mathematicians analyze two different coupon options for the better deal. They use different scenarios to predict and compare the outcomes. 

Young mathematicians demonstrate what they know about measurement with a four-task assessment that focuses on estimation, length, and inches.

Build foundational knowledge of volume by building boxes. Given dimensions for a piece of grid paper, young mathematicians determine the number of possible open-top boxes it will make. As part of this task, they also find the box with...
