Join the tree house detectives in learning about the processes of the water cycle, water conservation, water treatment, and water as a limited resource.

To conclude a unit on the concept of diversity in world literature, class members conduct a symposium on "African Literature in Global Perspectives." In order to earn a spot on the panel, individuals craft an original thesis that...

Are you wishing for a great grammar presentation? Wish no longer with an engaging slideshow that focuses on the conditional verb form. Learners begin their sentences with wish before completing them with the correct usage.

Reinforce U.S. Constitution facts with a crossword puzzle. Scholars show what they know by completing the 53 prompts. 

The present tense is a helpful skill to review in any language arts classroom. Focusing on statements made in the affirmative and in the negative, a slideshow presentation guides pupils through grammar rules and examples for the simple...

Based on their understanding of the Universal Declaration of Human Rights and the Rights of Migrants in the United States, groups adopt a human rights perspective and analyze media reports to evaluate how the US is addressing the...

How do jewelers tell the difference between diamonds, glass, and cubic zirconia? A sparkling simulation demonstrates how to use a ray of light to determine the substance and ideal shape for a diamond. Scholars control the material,...

Explore the scientific process through nature. Scholars become scientists as they develop a question, design an experiment, collect data, and analyze their results. A two-week lesson guides your classes through the process and provides...

Collaboration is the key for this equation-solving lesson. Learners solve a multi-step linear equation that requires using the distributive property. Within collaborative groups, scholars discuss multiple methods and troubleshoot mistakes.

Within collaborative groups, scholars factor a degree six polynomial. They can factor the polynomial using many different strategies — a great way to prompt mathematical discussion.

Explore a basic pattern to practice writing expressions. In collaborative groups, learners examine a contextual pattern and write an expression to model it. The task encourages groups to describe the pattern in multiple ways.

Dig into a classic math problem with your classes. Through an engaging task, learners work with rate and distance information to make conclusions. In the task, two people walk at different rates; one leaves first, and scholars...

It seems the post office has run out of stamps! Learners build all the values of postage available if the post office only sells five- and seven-cent stamps. The task provides an opportunity to create an expression in two variables and...

Explore the measures of central tendency through a challenging task. Given values for the mean, median, mode, and range, collaborative groups create a set of data that would produce those values. They then critique other answers and...

Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared...

Discover relationships between linear and nonlinear functions. Initially, a set of data seems linear, but upon further exploration, pupils realize the data can model an infinite number of functions. Scholars use multiple representations...

Number patterns can seem mysterious. Help your learners unravel these mysteries as they complete an intriguing task. Through examination, collaborative groups determine that they are able to produce all integers above a certain...

Is it possible for a rectangle to have the same area and perimeter? If you disregard units, it happens! In a challenging task, groups work to determine the rectangles that meet these criterion. The hope is that learners will naturally...

Model geometric concepts through a hands-on approach. Learners apply similar triangle relationships to solve for an unknown side length. Before they find the solution, they describe the transformation to help identify corresponding sides.

Evaluate patterns of numbers through an engaging task. Scholars work collaboratively to determine a general rule reflecting the sum of consecutive positive integers. Multiple patterns emerge as learners explore different arrangements.

What makes a good sample? Your classes collaborate to answer this question through a task involving areas of rectangles. Given a set of 100 rectangles, they sample a set of five rectangles to estimate the average area of the figures. The...

Teach solving absolute value inequalities through inquiry. Groups use their knowledge of absolute value and solving inequalities to find a solution set to an absolute value inequality. Working collaboratively encourages discussion,...

Where in the world (or at least in the coordinate plane) is the third vertex? Given two coordinate points for the vertices of a triangle, individuals find the location of the third vertex. They read an account of fictional...

Geometric figures are perfect to use for proofs. Scholars prove conjectures about whether given points lie on a triangle and about midpoints. They use a provided dialogue among fictional students to frame their responses.
