Third graders explore the concept of linear measurements and how they work. Coins are used to reinforce the process.

In this length and width learning exercise, 2nd graders draw 6 specific items or objects that are the following measurements: 6 feet tall, 3 inches long, 9 inches long, 1 inch wide, 25 feet long and 4 feet long.

Students measure respiratory rates on live toads, and the effect water temperature has on their findings.  In this scientific method lesson, students record their findings and present them in a graph, comparing the results.

In this test for parallelograms instructional activity, students solve 15 short answer problems. Students determine if a given sketch is a parallelogram given angle measures and/or side lengths. Students use knowledge of parallelograms...

Students conduct experiments to determine if length, mass, or starting angle has any effect on the rate of a pendulum's swing. They also conduct an experiment online to determine if gravitational force plays a role in the swing. Groups...

Not all triangles are right! Pupils learn to tackle non-right triangles using the Law of Sines and Law of Cosines. After using the two laws, they then apply them to word problems. 

Do flexible circuits change dimensions during fabrication? Groups use GeoGebra software to measure the length of pictures of flexible nano-circuits. To determine if the circuits change dimensions, future engineers use Microsoft...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

How accurate are robots? Groups draw lines by moving robots backwards and forwards by one rotation of the wheels. Using the appropriate formula, they determine the percent error in the length of the lines in relation to the calculated...

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Even though there is a wide variety of different triangles in the world, knowing a single equation allows us to find the area of each and every one of them. Follow along with this step-by-step presentation as Zoe clearly models how to...

Buying a new sofa? Learn how to use the Pythagorean Theorem, as well as algebra and graphing techniques, to determine whether the sofa will fit around a corner (which I'm sure you'll agree is a very important consideration!).

Learners build confidence working with geometric tools and develop their construction techniques in the sixth lesson plan of the 29-part series. Given a geometric description, they use a compass, protractor, or ruler to create it....

Second graders distinguish between and use nonstandard and standard units of measurement, use appropriate tools and techniques to measure length and width, and record and interpret data using graphs.

Students measure distances using indirect measurements. In this geometry lesson, students apply proportion and ratios to measure heights of different objects. They differentiate between direct and indirect measurements.

Students differentiate between the different properties of arcs, arc lengths, chords, and chord lengths. In this circles lesson, students calculate the arc length of a given circle, and find the measure of the inscribed angles of a...

Learners measure and apply their knowledge of proportion to solve problems. In this geometry lesson, students measure using a meter stick, small mirror and measuring tape. They compare and contrast their measurements to objects outside...

In this measurement activity, 3rd graders, working with a partner, choose two different units out of five to measure the length of their classroom. Students estimate first and then measure.

High schoolers investigate how the Earth's rotation affect the length of day. In this earth science lesson, students construct a sighting apparatus and record their observations over a few days. They analyze data collected and formulate...

Ninth graders research weapons of the Aboriginal people and throw a dart with and without the use of an atlatl. For this cross curricular lesson, 9th graders research the weapons of the Aboriginal people. They throw darts with and...

Students measure prisms and determine their volume. In this measurement and reasoning lesson, students estimate the volume and area of prisms. They measure given boxes. Students use paper to create prisms and cylinders. They determine...

Fifth graders throw darts, collecting data for distance traveled. For this data analysis lesson, 5th graders throw a dart using an atlatl. They calculate the speed for each throw and determine the best dart length for distance throws.

High schoolers use similar triangles to find missing heights.  In this using similar triangles to find missing heights lesson, students use proportions to find the heights of missing side lengths.  High schoolers find the...

Students measure using the Pythagorean Theorem. In this geometry instructional activity, students solve right triangles using the properties of the Pythagorean theorem. They apply the same knowledge to solving story problems.
