Young mathematicians rotate, flip, and sort their way to an understanding of the different attributes of geometric figures. Using transparent yellow and blue shapes, children try to match congruent figures together...

Your class may believe that geometry is a trial, but they don't know how right they are. A thorough math lesson combines the laws of logic with the laws of geometry. As high schoolers review the work of historical mathematicians and...

No height? No problem! Learners use their knowledge and a little help from GeoGebra to develop the Law of Sines formula. The Law of Sines helps to determine the height of triangles to calculate the area.

Get lost in the classifications. Using the backdrop of the Bermuda Triangle, pupils classify it by angle and side measures. They also learn information about the triangle and its history.

Isn't paper pushing supposed to be boring? Learners attempt a paper-pushing puzzle to develop ideas about angles inscribed on a diameter of a circle. Learners then formalize Thales' theorem and use geometric properties to develop a proof...

Facilitate creativity in your math class as individuals learn the definition of a geometric reflection and correctly construct a model, as well as its reflected image. They use a perpendicular bisector and circles to elaborate on...

The final lesson in a series on theatre design spotlights how lighting is incorporated into a production. After watching videos that focus on lighting fixtures and their positioning, individuals create a basic design plan for a scene,...

Who needs a barbecue grill to cook hot dogs when you have the amazing power of the sun at your disposal? Engage young scientists in learning about solar energy with this fun activity that turns a used Pringles can into a solar...

Hit a bullseye with an engaging presentation about the components of projectile motion. Viewers see how horizontal and vertical motion combine to create the parabolic path of projectile motion. 

Does doubling mean everything doubles? Learners adjust the scale factor between two rectangles. Using the calculated measurements, pupils investigate the ratios between the lengths, perimeters, and areas of the rectangles.

Five steps walk scholars through the process of drawing a Monarch butterfly. Participants research the insect, make observations, trace, then color. 

Parallelograms are pairs of triangles all the way around. Pupils measure to determine the area and perimeter of a parallelogram. They then find the area of the tirangles formed by drawing a diagonal of the parallelogram and compare their...

Remove any ambiguity about using a helpful resource. Individuals use an interactive to find the number of triangles that fit given conditions. They find that some conditions can result in more than one triangle in the ambiguous case.

Laws of motion apply both in space and on Earth. Young experimenters model object impact on the Earth and moon. They use data to determine the effect mass and velocity have on the resulting craters and how that relates to the energy of...

Geometry—it's not just for the math classroom! Learners explore the field of forestry through a mathematical lens. An instructional resource explains how forest workers collect data about trees such as height, diameter, and age...

Pupils put together their own stroboscopes so that they can observe how cyclically moving images appear to merge into a singular object. This, and several other activities published by the same source, illuminate the way the brain...

Don't stuff money under your mattress. To find out why learners first complete a task determining how $24,000 in cash would affect the height of a mattress and whether this same amount would fit into a suitcase of given dimensions....

Learners practice relating rules of trigonometry and properties of circles. With a few simplifying assumptions such as a perfectly round earth, young mathematicians calculate the lengths of various paths between satellite and...

Translate the Common Core math standards into a series of achievable "I can" statements with this collection of classroom displays. Offering posters for each standard, this resource is a great way to support your seventh graders as...

If you need an array of worksheets to augment your science lessons, peruse a collection of assignments that is sure to fit your needs. With topics such as metric conversion, the scientific method, textbook features, research skills,...

Groups plan their escape carefully. Three three-tiered puzzles help a story character escape their situation, each involving integer sequences, transformations, and geometric constructions. The teacher resource includes...

The seventh segment in an eight-part unit promotes the idea of concentrating the sun to increase the power of a photovoltaic panel. Pupils learn about devices used such as reflectors or lenses.

Communication is the key. A presentation provides 25 sample items for Claim 3, Communicating Reasoning, for the Smarter Balanced High School Math assessment. Items require pupils to answer the question and provide logical reasoning to...

Communication is key. Eight sample items show how important communication and reasoning is for sixth grade mathematics. Part of the Claim 2-4 slide show series, the presentation uses concepts from fifth and sixth grade to illicit...
