Audio speakers, hard drives, credit cards, and even the earth use magnetic fields. While we observe the effect of magnetic fields, we can't actually see them. A viewer helps participants explore magnetic fields, some of the items that...

How can you tell if someone is happy? The lesson works with elementary and middle school scholars to activate their schema and pay attention to details to make inferences in their daily lives, poetry, and other literature. Cleverly...

How do you prevent the spread of water-borne illness in large public swimming areas? Scholars discover the challenges to identifying safe water through an inquiry experiment. They then produce posters sharing their understanding of water...

Planning a party of 45 guests may be more complicated than it would seem.  Learners must design the space in accordance with these constraints about the space available in the room. They need to calculate area, circumference,...

Drop a perfect project into your lesson plans. Groups use different building materials to create models of parachutes for food drops. After testing out their prototypes, they make improvements to their designs.

The truth will always come out. A short performance task has learners considering a witness statement given to a detective. They apply special line segments in triangles and Ceva's Theorem to prove that the witness is actually lying.

How is life in Northern Europe different from other areas of the world? Historians journey through the various regions of Northern Europe discovering what type of climate, animals, and lifestyles exist in that section of the world. They...

The corona virus pandemic is indeed a historic event. A time capsule activity permits young historians to document these days of social distancing, remote learning, and quarantine by collecting artifacts that capture what their lives are...

Scholars build a weather station equipped with a wind vane, rain gauge, and barometer. Following an informative page about the weather, learners follow steps to build their pieces then turn into meteorologists to chart the weather they...

Get kids interested in stargazing with a step-by-step guide. The guide begins with the do's and don'ts, what the defines a star, and introduces a journal. The page is linked to see stars if light pollution keeps stars away in your area.

What do you need to prove triangles are similar? Learners answer this question through a construction exploration. Once they establish the criteria, they use the congruence and proportionality properties of similar objects to find...

How can you formally assess understanding of circle concepts? Pupils take a mid-module assessment containing five questions, each with multiple parts.

Everyone's heard of Pythagoras, but who's Ptolemy? Learners test Ptolemy's Theorem using a specific cyclic quadrilateral and a ruler in the 22nd installment of a 23-part module. They then work through a proof of the theorem.

What do you get when you cross a circle and a line? One, two, or maybe no solutions! Teach learners to find solutions of quadratic and linear systems. Connect the visual representation of the graph to the abstract algebraic methods. 

Allow your pupils to become the mathematicians! Individuals explore the properties of a midsegment of a triangle through construction and measurement. Once they figure out the properties, learners use them to draw conclusions.

How do you know if a pair of triangles are congruent? Use the instructional activity to help class members become comfortable identifying the congruence criteria. They begin with an exploration of ASA and SSS criteria through...

Learn transformations through constructions! Pupils use perpendicular bisectors to understand the movement of a reflection and rotation. They discover that the perpendicular bisector(s) determine the line of reflection and the...

How well does the class understand dilations? The three-part assessment presents problems related to the properties of dilations. Pupils perform dilations and determine whether a dilation is responsible for a specific image.

Construct tangent lines and make the connection to tangent functions. An informative lesson reviews the geometry origins of the tangent function. Pupils use that information to determine how to construct a tangent to a circle from a...

Investigate the relationship between irrational roots and a number line with a resource that asks learners to put together a number line using radical intervals rather than integers. A great progression, they build on their understanding...

In this camping learning exercise, students identify camping objects by answering multiple choice questions. Students complete 10 multiple choice questions about camping.

In this famous person learning exercise, learners answer 10 multiple choice questions about the life and times of Albert Einstein. They answer questions about his childhood, first jobs and scientific theories.

Learners map their playground as if it were an archeological site. They locate objects on the playground and determine their location using coordinate points. A related lesson is Coordinate Grid: Mapping an Archeological Site.

Students make a flying wheel and measure its flight.
