Mr. Wormwood, one of the characters in Roald Dahl's Matilda, is not the most trustworthy of characters. Have student groups take on the roles of car salespeople and play a game to see who can make the most profit by selling...

No chaperones are necessary to use this resource. Scholars solve a multi-step inequality problem on summer camp chaperones by using a pictorial representation. They write inequalities to represent various situations in this context.

Connect the dots to graph a linear function. Young mathematicians use an interactive to first plot provided points on a coordinate plane. They connect these points with a line and then answer questions about the slope and y-intercept of...

One quadrant just isn't enough. Pupils learn to plot points in the four quadrants of a coordinate plane using an interactive. A set of challenge questions tests their understanding of the skill.

Where in the world (or at least in the coordinate plane) is the third vertex? Given two coordinate points for the vertices of a triangle, individuals find the location of the third vertex. They read an account of fictional...

Number patterns can seem mysterious. Help your learners unravel these mysteries as they complete an intriguing task. Through examination, collaborative groups determine that they are able to produce all integers above a certain...

Sorting your t-shirts is easy with Venn diagrams. Individuals use a drag and drop interactive to classify shapes on t-shirts into Venn diagrams. A set of challenge questions tests whether the classification is correct.

Keep your heads up while counting. Pupils use an interactive to create a table with the possible outcomes of flipping three coins and then determine the probabilities of getting certain combinations of heads and tails.

But I have nothing to wear! Using an interactive, individuals create all possible outfits from three shirts, one belt, and two pairs of pants. Answering a set of challenge questions helps them see what they have learned from the...

Young mathematicians make a tree diagram of all possibilities for sandwiches using an interactive. They learn how multiplication speeds up the process of finding the number of outcomes.

Scholars determine the number of possible outcomes when a spinner is spun three times. They start with the case of one spin and build up to the case of three spins.

Yes, Venn diagrams are helpful in science, too. Learners use an interactive to classify celestial bodies as having moons, as dwarf plants, as both, or as neither. They answer a set of challenge questions based on the Venn diagrams they...

Do people ride, slide, or do both? Pupils use an interactive Venn diagram for the numbers of people owning bicycles, owning skateboards, or both. An interactive provides questions for them to answer using the diagram.

Learners use an interactive to determine the probability that a soccer player will score a goal. Given data over the course of several days, they determine probabilities for several different situations.

Future mathematicians use an interactive to see how changing the size of a basketball court and the size of a region in the court affects the probability that a ball will randomly fall within the specified region. No calculations are...

Stockings make your legs warmer and math more enjoyable. A drag-and-drop interactive has pupils take stockings out of drawers to calculate probabilities. This includes dependent events where the probabilities depend on previous stocking...

It's not in the bag. An interactive provides the probability of picking a certain color marble from a bag after several marbles have been removed. Young mathematicians learn about dependent events from this resource.

Take a bite out of an enticing resource. Scholars use an interactive to study dependent events. They see how the number of favorable outcomes and total number of outcomes changes as individuals "eat" pieces of pizza.

Explore a basic pattern to practice writing expressions. In collaborative groups, learners examine a contextual pattern and write an expression to model it. The task encourages groups to describe the pattern in multiple ways.

Explore the measures of central tendency through a challenging task. Given values for the mean, median, mode, and range, collaborative groups create a set of data that would produce those values. They then critique other answers and...

Evaluate patterns of numbers through an engaging task. Scholars work collaboratively to determine a general rule reflecting the sum of consecutive positive integers. Multiple patterns emerge as learners explore different arrangements.

Teach solving absolute value inequalities through inquiry. Groups use their knowledge of absolute value and solving inequalities to find a solution set to an absolute value inequality. Working collaboratively encourages discussion,...

Collaboration is the key for this equation-solving lesson. Learners solve a multi-step linear equation that requires using the distributive property. Within collaborative groups, scholars discuss multiple methods and troubleshoot mistakes.

What makes a good sample? Your classes collaborate to answer this question through a task involving areas of rectangles. Given a set of 100 rectangles, they sample a set of five rectangles to estimate the average area of the figures. The...
