Eight groups in your class are each responsible for a different aspect of surveying the campus for a suitable rain garden location. Features to consider include water flow, topography, sun/shade patterns, land surface, vegetation,...

This comprehensive unit investigates transformations of quadratics, having learners follow "Optima" through the development and growth of her quilting business. Deftly weaving the story into the mathematical mechanics, the unit gives...

Through a variety of hands-on activities and physical scenarios, this far-reaching unit leads learners through an exceptionally thorough exploration of circles and parabolas as conic sections. Geometric construction techniques are used...

Have a hopping good time teaching your class how to collect and graph data with this fun activity-based instructional activity series. Using the provided data taken from a frog jumping contest,...

Natural human interest in patterns and algebraic study of function notation are linked in this introductory unit on the properties of sequences. Once presented with a pattern or situation, the class works through how to justify...

The language and features of functions get careful treatment in a complex but doable lesson. Learners get a lot of practice really figuring out what a graph means in context, and also identifying key features of graphs. Key ideas...

Sequences and series are traditionally thought of as topics for the pre-calculus or calculus class, when learners are figuring out how to develop limits. But this unit uses patterns and slopes of linear functions in unique ways...

How do two administrations work together to craft a seamless transition of power? Learn more about personnel management, policy implementation, and the role of an outgoing president with a transition plan designed for the 2012...

Explore the excitement and ethical challenges of CRISPR and genetic-editing technology. Participants engage in do-nows, view a slideshow, and collaborate on scenarios about genetic editing. Group members analyze scenarios to generate...

Eugenics philosophy takes survival of the fittest to a whole new level. With a research-focused activity, young scientists examine the history of the eugenics movement and its impact on society. Pupils engage with a video clip, primary...

Teach your class the descriptive characteristics of soil. Provide information about particle size and a flow chart for assessing texture. Soil scientists then analyze samples and hypothesize which would be the best type for a rain...

Middle schoolers discover why it's important to establish a positive credit history and understand the value of credit reports to lenders and borrowers. They apply legal guidelines to establish the uses of a credit report other than...

Young surveyors look for patterns in water flow around campus. Using a map of the school (that you will need to create), they mark the direction of the path of water. They also perform calculations for the volume that becomes runoff. The...

Take young scholars on a trip through history with this unit on the mathematics and architecture of the Mayan civilization. Starting with a introduction to their base twenty number system and the symbols they used, this eight-lesson unit...

How can you tell if a number of items is reasonable? Combine math and language arts with a fun lesson based on Jeff Shepard's The Right Number of Elephants. After reading the book, kids discuss amounts of other items and create...

Inquiry-based learning and investigations form the basis of a deep understanding of quadratic functions in a very thorough unit plan.  Learners develop recursive and closed methods for representing real-life situations,...

Learners tackle a wide range of intimidating topics in this comprehensive unit that spans piecewise functions, absolute value of functions, and inverse functions (among other topics). Investigative group work alternates with more...

Probability, especially conditional probability, can be a slippery concept for young statisticians.  Statements that seem self-evident on the surface often require a daunting amount of calculations to explicate, or turn out to be...

Why are bees so important? After several activities where kids investigate the form and function of flowers, they learn about the different types of bees and label them. They then examine pollen under a microscope and decide which bees...

The coordinate plane links key geometry and algebra concepts in this approachable but rigorous unit. The class starts by developing the distance formula from the Pythagorean Theorem, then moves to applications of slope. Activities...
