What an impressive task it is to make dental impressions! Pupils learn how dentists use proportional reasoning, unit conversions, and systems of equations to estimate the materials needed to make stone models of dental impressions....

Get a line on the snakes. The assessment task requires the class to determine the species of unknown snakes based upon collected data. Individuals analyze two scatter plots and determine the most likely species for five...

Population density, it is not all that it is plotted to be. Pupils analyze a scatter plot of population versus area for some of the states in the US. The class members respond to eight questions about the graph, specific points and...

Create a neuron frenzy as your pupils play the part of the neurons. An engaging lesson creates a human chain of neurons that pass cotton balls posing as neurotransmitters. Scholars learn about pre- and post-synapses as they complete...

A chicken egg is a very large cell—perfect for investigating osmosis! Scholars conduct an experiment with vinegar and eggs that helps them understand the process of osmosis. They follow the activity with an in-depth look at osmosis...

Explore the power of mathematics through this two-week statistics unit. Pupils learn about several climate-related issues and complete surveys that communicate their perceptions. They graph both univariate and bivariate data and use...

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

Students create 8 inch, or bigger, clay sculptures of the human form in this Art lesson introducing clay sculpting techniques. The works of artists studied in preparation include Henry Moore, Michelangelo, Degas, Rodin and John Quincy...

A thorough and fun lesson on Korea! In groups of four (Social Chair, Historian, Translator, Travel Agent) class members research North and South Korea to determine a good location for an overseas institute for studying abroad. Once this...

Investigate the relationship between height and arm span. Young statisticians measure the heights and arm spans of each class member and create a scatter plot using the data. They draw a line of best fit and use its slope to explain the...

How do doctors predict a child's future height? Scholars use one case study to determine the height of a child two years into the future. They graph the given data, determine the line of best fit, and use that to estimate the height in...

Pupils use the provided census data to guess the future height of a child. They organize and plot the data, solve for the line of best fit, and determine the likely height and range for a specific age. 

Class members research citizenship in Ancient Rome and in the United States and use the provided graphic organizers to compare the rights and responsibilities of citizens in these two democracies.

Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Put the better archer in a box. The performance task has pupils compare the performance of two archers using box-and-whisker plots. The resource includes sample responses that are useful in comparing individuals' work to others.

What's the opposite of multiplying binomials? Learners apply their previous knowledge of multiplying binomials using algebra tiles to factor trinomials. The lesson introduces factoring as a process that uses algebra tiles to...

Run a simulated airplane manufacturing plant with your pupils as the builders! Learners build Lego airplane models and collect data on the rate of production, comparing the number produced to the number defective. Using linear...

We taste with our taste buds, so why do flavors change when we have a stuffy nose? Scholars experiment with taste testing while holding their noses and then while smelling. They record their observations in pairs and come together to...

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

This lesson introduces the idea of slope and defines it as a numerical measurement of the steepness of a line. Pupils then use the definition to compare lines, find positive and negative slopes, and notice their definition holds for...

Is there a relationship between height and the number of siblings? Classmates collect data on their heights and numbers of brothers and sisters. They apply statistical methods to determine if such a relationship exists.

Young historians view and analyze photos and documents from WWII that are related to blood transfusions and blood plasma. A demonstration of correct and incorrect blood donors visually shows the importance of knowing blood...
