Help Christina figure out how many chocolate and lemon candies she has with a lesson on decomposing numbers. When presenting this context to the class, the teacher chooses the total number of candies and the number that are chocolate,...

Drawing from a scenario of the history of the penny, learners write and solve a system of linear equations from a context.

Drawing from a scenario of the history of the penny, learners write and solve a system of linear equations from a context.

This un-scaffold summative assessment tasks learners to use the height of a bouncing basketball, given the data in graph and table form, to choose the model that is represented. Learners then use the model to answer questions about...

Teach young mathematicians that sometimes just getting close to the exact answer is perfectly fine, by using this collection of estimation worksheets.

Young scholars write and solve linear equations in one variable based on descriptions of the operations that are applied to the unknown variable in an algebra machine. They then create their own problems for classmates to solve.

Round and round we go. Learners first complete a task on writing equations of circles. They then take part in a collaborative activity categorizing a set of equations for circles based on the radius and center.

To examine mathematical functions in a modeling situation pupils combine quadratic and step functions to represent a presented scenario. They both graph and write a function to represent data shown in a table. 

Ever wonder if you can trust the pump that pumps your gas? Budding mathematicians use video evidence to analyze the cost-per-gallon ratio at different intervals for three different pumps. Their goal is to identify the pump that is...

Weight is a function of the distance from sea level. Learners explore the many implications of this fact in an inquiry-based task. Given the function, pupils answer questions before manipulating the function to rewrite the distance...

What if a coordinate plane becomes a slope-intercept plane? What does the graph of a linear function look like? Learners explore these questions by graphing the y-intercept of a linear equation as a function of its slope. The result is a...

It all adds up to one. Pupils solve several items that involve finding sums of fractions in relationship to a whole. The assessment task uses fractions with unlike denominators to determine the amount of a tank of gas and the amount of...

Just how far can I see? The short assessment question uses the Pythagorean Theorem to find the distance to the horizon from a given altitude. Scholars use the relationship of a tangent segment and the radius of a circle to find the...

Individuals play a computer game to terraform planets. Learners add plants, animals, fungi, and minerals to the planet surface by creating numerical expressions that represent the objects. After playing the game for a while, the class...

Identify the correct ratios for food. Pupils play a six-level online game to practice identifying ratios. Learners see ratios in several forms mixed in with non-ratio quantities. Individuals click on each ratio to feed the hungry martian...

Take time to tell the time. Players compete in an online game of tug of war as giraffes. They determine the correct time in words for the displayed analog clock. Each correct response pulls the rope just a little farther.

Pull hard to convert fractions. Players participate in a tug of war against each other or the computer by practicing converting fractions to decimals. With each correct response, the player's puppy pulls a little harder. Play continues...

Science can be quite tasty. A delectable unit from NASA shows learners why it's important to consider food, nutrition, and health in space. Four lessons explore the idea in great depth, including testing cookie recipes. Along the way,...

Model how the sun's energy strikes the planet and help your class relate it to a climate map. Assign small groups an individual climate zone to discuss. They reflect on and research how humans survive in the assigned climate and write a...

Are opioids the most abused drug after marijuana? How hard is it for young people to obtain painkillers without a prescription? Middle and high schoolers explore the growing epidemic of opioid addiction with a lesson that prompts them to...

In this 4th grade math review worksheet, students respond to 60 multiple choice questions that review of fractions, decimals, geometry, number sense, and computation.

In this polygons and angles activity, 10th graders complete 5 different questions related to polygons and angles, in addition to symmetry and transformations. First, they define polygon and how they are named. Then, students define...

Third graders use candy to explore whole numbers one to hundred thousand. They place candy on a place value chart and explore how sweet math can be.
