Graphing paper, pencil, ruler, protractor, and compass, all get replaced or supplemented with this dynamic geometry application. Here, you can create, move, and scale many different shapes, as well as, explore and change their properties...

Here is an assessment designed to test mathematicians' knowledge of writing numbers, comparing numbers, skip counting, solving addition and subtraction problems; along with measuring objects, telling time, identifying shapes, reading...

Students estimate the circumference of a pumpkin. They measure the pumpkin and other school objects, and record the measurements on worksheets.

The Kuril islands stretch from Japan to Russia, and the ongoing dispute about their jurisdiction prevents many scientific research studies. Scholars learn to create a topographic profile of a specific area around their schools. Then they...

Test scholars mathematic skills with an assessment addressing addition, subtraction, multiplication, place value, measurement, geometric shapes, expanded notation; and their ability to compare numbers, write number...

The incredibly shrinking meter—decimeters to centimeters, to millimeters, and now to nanometers! Learners may have a difficult time visualizing particles on a nanoscale. Help them see a little clearer using a well-designed lesson...

Chart your way to an understanding of nanoscale. Using a Google map, learners estimate a radius around their location of 1,000 and 1,000,000 meters. Predicting what 1,000,000,000 meters would look like takes them off the charts!...

Young scientists grab their measuring tapes, rulers, and yard sticks as they see how big Arctic animals really are. To conceptualize the trait of height or length, each small group will measure out the entire length of an arctic animal....

Isn't technology great? The 12th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces technology that marine scientists use. Pupils take part in an activity using conductivity,...

Explore angle relationships associated with transversals. Pupils construct parallel lines with a transversal and find the measures of the angles formed. They figure out how the different angles are related before constructing...

Certain materials do not always maintain the same physical properties when they exist in the nanoscale. Help your classes to explore this idea through an experimental lesson. Scholars use spectroscopy with samples of silver solution...

Use a West African folktale to practice several different skills in your first grade classroom. Learners read The Clever Monkey Rides Again and focus on rhyming words, reading comprehension, measurement, art, movement, and word...

Test your scholars' knowledge of a multitude of concepts with an assessment aligned to the California math standards. Using the exam, class members show what they know about the four operations, positive and negative numbers, statistics...

Connect your pupils to the problem by presenting a situation with which they can identify. Individuals analyze a graph of water use at a school by reasoning and making conclusions about the day. The lesson emphasizes units and...

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Build upon the Pythagorean Theorem with the Law of Cosines. The 10th part of a 16-part series introduces the Law of Cosines. Class members use the the geometric representation of the Pythagorean Theorem to develop a proof of the Law of...

Who needs a plan — let trigonometry protect you! Pupils determine the angle of an approaching enemy to a village wall. The scholars determine the exact value of trigonometric functions for the angle. Class members use trigonometry to...

Collaborative groups examine the importance of energy resources on quality of life by researching different energy sources and alternative energy sources through data analysis. They make a comparison of different countries and cultures,...

How do you put something as large as the universe in perspective? Use a series of scale experiments. Classmates collaborate around four experiments to examine the scale of the earth-moon system, our solar system, the Milky Way galaxy,...

Watch augmented reality bring classrooms to life. Scholars work in groups to design, build, and market a new pair of headphones meant for children under three. They use an augmented reality app to show their headphones in action as they...

Explore lines tangent to a circle. In this math lesson, students manipulate circles and lines on a TI calculator. They draw a circle  and analyze perpendicular lines intersecting the circle in only one place. This activity works...

Check in on the development of your fifth graders' reading and writing skills with this Common Core-designed assessment. Given a series of six reading passages ranging from narrative stories to informational texts, young...
