New ReviewSolving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...

New ReviewFind the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...

New ReviewNot all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

New ReviewA cross-curricular resource teaches and reinforces mathematical concepts with several activities that use parts of a newspaper. Scholars use scavenger hunts to find the different ways math is used in the paper along with using data...

New ReviewPicture books provide great learning opportunities for STEM. A curriculum resource document gives several lessons in each grade level for K-6. The activities have learners read a book before applying the engineering design process to...

New ReviewEight questions challenge mathematicians to multiply decimals. A color-coded tool with movable parts assist participants in answering word problems. Item response types include fill in the blank, multiple-choice, and a discussion.   

Estimating whole number multiplication and division is the focus of an interactive that uses a garden plot with moveable points to answer six questions.

Put expressions, equations, and inequalities to work! Young scholars solve problems using various strategies. Meant as a snapshot of the Smarter Balanced Assessment, a set of seven questions includes topics from writing expressions to...

While a stopped clock is right twice a day, a fast or slow clock confuses people for weeks. Scholars observe a clock running slow and must correct it before observing a clock running fast and working it backward. Finally, a multi-step...

Scholars learn about a series of three challenges when they design a bus system for a small town. They determine the bus routes and then figure out the best type of fuel to use before considering the cost of going electric. Learners...

Climb up the staircase of engineering knowledge. After watching a video of a carpenter measuring out steps for a set of stairs, pupils learn about the terminology and regulations involving stairs. They see how to use a rule of thumb when...

Pick the resource while it's ripe. A performance task challenges young mathematicians to consider the costs of apple picking. They compare the costs for two different orchards for different situations.
