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.

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.

In order to create some tasty fudge, learners must adapt a recipe. Using a recipe for fudge, ingredients must be correctly converted using fractions. If one fraction is incorrect, the fudge will reveal it! Although you will only make one...

Young scholars conduct research on 1830s families and early New England culture. They conduct research on the Old Sturbridge Village website, participate in an online chat with a costumed interpreter, and continue to develop possible...

Second graders investigate the business community in their own town. They design interview questions before interviewing business people. They look at what type of good and services are offered in their area. They design a multimedia...

Get out those bells, sand blocks, and sticks! Your kindergarteners use their singing voices to ask and answer friendly questions while keeping rhythm. They take turns in a group and in pairs singing questions and answers while keeping...

Elementary schoolers view and study ten pictures of the location of a ball adjacent to a box. They decide where the ball is and match it to its appropriate preposition on the right. A good language arts lesson!

Kids consider the pure abstraction and minimalism found in Mary Heilmann's work. They analyze several of her pieces through critical discussion and then think about her use of a song title as the title of her exhibit. Learners then use a...

Focusing primarily on Confucianism, these slides contrast the philosophies of India with those of China - and introduce the philosophies of Legalism and Daoism as well. Your world history lecture will come alive with the clear outlines...

No rules...awesome! Or is it? It's tough for young learners to think about what would happen if a rule didn't exist, but understanding the rules and where they come from helps keep everyone safe. Youngsters write a rule on the front of...
