Time is on your side. Scholars plot three points on number lines with different time units to represent the time it takes three people to bake pies. They determine the fastest baker and the difference in times between the bakers.

Mixed numbers are the focus of a five-question interactive. Scholars move fraction pieces into strips and equations to find solutions. Questions challenge participants with multiple-choice, a true or false, and one discussion.

Five questions—multiple-choice, fill in the blank, and discussion—make up an interactive that challenges scholars to mail a teddy bear using the smallest box possible without squishing it. A box with movable sides allows mathematicians...

After a full day of selling lemonade, three friends split the cost of the profit money. If the total profit was $34.20, how much will each friend get?

How many miles did a car travel if it traveled at 55mph for three hours? What are the factors for this multiplication sentence? These are the questions young mathematicians must solve using a multiplication map.

Five questions make up an interactive all about whole-number exponents. Movable building blocks create a visual tool to aide mathematicians in answering multiple-choice and true or false problems. The interactive ends with a discussion...

Mathematicians solve six multiple-choice and true or false questions using their knowledge of estimation and multiplying decimals. The interactive provides a garden-themed tool that creates a visual aid of three watering cans to assist...

An interactive challenges mathematicians to add mixed fractions with unlike denominators. Five questions—fill-in-the-blank and multiple-choice—build from one to the next leading the way to an open discussion about denominators and...

An interactive resource challenges mathematicians to show what they know about prime factorization. Five multiple-choice, true or false, and discussion questions use chocolate chip cookies to set a real-world application of the...

Find the right number of vectors to get to the finish line. Using a boat race scenario, pupils add multiples of the same vector together. The scholars use scalar multiplication to speed up the boats in an exciting race to the finish. 

Determine whether the payoff is worth it. Pupils calculate the expected value of a game with three different payoff levels. Each level has a different probability of winning money. The scholars find the expected payoffs for each...
