This PowerPoint addresses fifth grade math concepts, focusing mostly on geometry. The interactive math review game is in a "Jeopardy" style format and enables students to revisit the topics in geometry such as polygons, quadrilaterals...

Students become familiar with the causes for formation of shadows. They create shadows, compare the size and shape of the shadow with the actual object, engage in shadow play theatre, and discover what happens to shadows when there is...

In this AC phase worksheet, students answer 24 questions about AC and DC voltages, phasor diagrams, sine wave graphs and Lissajous figures.

Second graders identify the attributes of various shapes and estimate the weight of the objects. In this geometry lesson, 2nd graders identify the attributes of concrete objects and use a pan balance to weight them.

Address key vocabulary in the seventh grade Common Core Math Standards with this comprehensive list. A series of word cards is also provided that supports each term with images and examples, making this an excellent tool for teaching the...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

Time for classes to show what they've learned. Use several tasks to assess understanding of the trigonometric functions, unit circle, radians, and basic trigonometric identities.

This activity is a follow-on activity to inscribing a square in a circle. The overall problem is more complex. It deals with geometric constructions, properties of triangles, and regular hexagons. The final part of the activity...

There are many different ways to show a proof of the Pythagorean Theorem.  Here is a nice hands-on paper cutting activity that shows a graphic representation. You can even challenge your young Pythagoreans to come up with their own...

Increase the level of assessment rigor with the test of performance tasks. Topics include similar triangles, trigonometric ratios, Law of Sines, Law of Cosines, and trigonometric problem solving. 

Breaking the rules is one thing, proving it is another! Learners expand on their previous understanding of congruence and apply a mathematical definition to transformations. They perform and identify a sequence of transformations and use...

What figure is formed by connecting the midpoints of the sides of a quadrilateral? The geometry assessment task has class members work through the process of determining the figure inscribed in a quadrilateral. Pupils use geometric...

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

Students compare graphs of their data that was generated on a NASA website.  For this seasons lesson students complete a lab activity. 

Here is a very interesting way of studying triangles and polygons. Pupils work together and use pieces of string to create a variety of shapes. Depending on how many kids are manipulating the string at any one time, the number of...

Show your class that trigonometric functions have characteristics of their own. A resource explores the features of trigonometric functions. Learners then connect those concepts to inverse trigonometric functions and trigonometric...

In this geometric calculations of solar storms learning exercise, students use a diagram indicating the location of 2 STEREO satellites, the earth and the sun to calculate the distance between a Coronal Mass Ejection and the Earth. They...

In this angular size learning exercise, learners read about how astronomers determine the size of objects in the sky by using their angular size. Students are given equations that allow scientists to convert the angular size into...

For this geometry worksheet, 10th graders use a graphing calculator to evaluate trigonometric functions and their inverses. The four page worksheet contains explanation, examples, and twenty questions. Answers are not...

In this math worksheet, students examine 14 problems inside geometric shapes. Students solve the simple addition or subtraction problems and color the shape blue if the answer is even and red if it is odd.

In this algebra worksheet, students solve linear equations using one and two steps. They solve systems of equations using substitution and elimination with graphing. There are links for ready made tests and quizzes.

Students identify different locations on a unit circle. In this precalculus lesson, students identify the different trig properties and rewrite the equation of a circle in standard form. They use mnemonic devices to help them...

Students grow salt crystals by making a saturated solution of table salt and let the solution sit around and evaporate.

Students participate in an experiment to discover the properties of lift. They work together to complete calculations and collect data. They share their results with the class.
