How many ways can you stock a shelf? It's probably more than you think! Young scholars use data in a frequency table to determine how many ways to stock a shelf given a specific constraint for types of groups. They then repeat the task...

Learners explore the meaning of groups formed through permutations and combinations with an activity that asks individuals to determine the total number of pupils needed to guarantee that at least one pair has the same initials....

Discover how much your young scientists know about biotic and abiotic factors with a two-question formative assessment that requires them to observe, list, and describe. 

Put those thinking hats on and look at all the possible outcomes from rolling two different four-sided dice. The challenge in this problem is finding all the combinations when adding and subtracting the numbers from each die and creating...

After watching a brief video on making metric conversions to standard units, pupils complete tables to describe certain items with the appropriate unit of measurement. Then, they convert liters to millimeters, millimeters to...

The test may say you have cancer, but sometimes the test is wrong. The provided task asks learners to analyze cancer statistics for a fictitious town. Given the rate of false positives, they interpret the meaning of this value in the...

A middle school test contains two 40-minute sections covering material through algebra. All questions involve applied problem solving or mathematical analysis.

The game should be fair at all costs. The mini-assessment revolves around the ability to use probabilities to determine whether a game is fair. Individuals determine compound events to calculate simple probabilities and make...

Subtracting mixed numbers is easy when the fractions have the same denominator. Here, young mathematicians are prompted to find out how many pounds of peaches are left after Alfredo gives some pounds to his neighbor.
