Give your students a fighting chance at understanding probability. Offering numerous examples that clearly demonstrate basic probability concepts, this resource helps young mathematicians learn how to visualize the...

Help your kids develop strategies for counting. In this base-ten instructional activity, learners use matching cards, base 10 blocks, and dry erase markers and boards to examine the base 10 counting system.

Via the concrete setting of estimating the population of the US, your algebra learners are introduced to a logistic growth model. Comparing and contrasting logistic, exponential, linear and quadratic models, to see which fits the data...

Does increasing the pressure between two moving plates provide a stabilizing force or create more destruction? The hands-on lesson encourages exploration of strike-split fault models. The sixth lesson in a 20-part series asks...

How many nurses does it take to support one doctor? A project-based activity asks learners to analyze state data to answer this question. Classes create polynomial functions from the data of doctors and nurses over a seven-year...

It's time to choose a position! Scholars read a model position paper about fracking to practice identifying the topic and argument. Then, working with a partner, they use a rubric to assess the essay. 

There are many ways to work through a multiplication problem. Using an area model, kids complete several worksheets with different types of multiplication problems, including multiplying by ten, and explain how the new strategies differ...

Behaviors are often based on assumptions. That's the big idea in the third lesson of a series of critical think resources. Through a series of worksheets, learners examine the conscious and heretofore unconscious assumptions that...

Context makes everything better! Groups use real data to create models and make predictions. Classmates compare an exponential model to a linear model, then consider the real-life implications. 

Examine trends in student-to-teacher ratios over time. Building from the first task in the two-part series, classes now explore the pattern of student-to-teacher ratios using a non-linear function. After trying to connect the pattern to...

Challenge young astronomers to demonstrate their knowledge of the solar system with this fun open-ended science project. Provided with a short list of requirements, students are given the freedom to use their creativity and whatever...

What do you call a skull without neurons? A no-brainer! A hands-on activity asks scholars to build a model of a neuron using beads. They use their models to study the parts of the neuron and their functions.

Apply geometric properties and formulae for surface area and volume by constructing a three-dimensional model of a city. Learners use similar and congruent figures and transformations to create a city of at least 10 buildings. They trade...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

Examine an innovative approach to a large-scale model. Pupils across the state of Maine teamed up to create a model of the solar system that spans 40 miles. Put thinking skills to work within your classes as they make the calculations to...

Modeling population growth gives learners an opportunity to experiment with real data. Comparing the growth rates in this real-life task strengthens learners' understanding that exponential functions change by equal factors over equal...

What do a sandwich bag and a mouth have in common? Your classes are about to find out in a hands-on lesson that has groups build models of the digestive system. Using a little imagination, learners use everyday materials to create a...

Do stars age gracefully? Young astronomers use colored paper and data on luminosity and temperature to model the changes of a star during its lifetime. They then compare models of stars of different mass and radii. 

Differentiate between models. Pupils watch as the video works through three examples of creating a differential equation to model a situation. Scholars use their knowledge of proportional relationships to set up the equations and to...

In this geometry lesson on cylinders, geometers explore how to find the smallest surface area for a given volume.  They use their knowledge to relate it to the real world by making a model of a livestock tank.

DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

Read like a writer. Scholars read a model literary analysis in preparation for a similar writing assignment before annotating each paragraph for the gist. Next, pupils devise a list of qualities of a strong literary analysis essay. 

From 3-D cities to building bridges, young engineers engage in innovative STEM challenges that promote brainstorming and collaboration. Learners take on the roles of different types of engineers as well as become familiar...

The second day of a two-part lesson on motion introduces the class to circular motion. Pupils learn how to incorporate a time parameter into the rotational matrix transformations they already know. The 24th installment in the 32-part...
