Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.

Begin seeing the world through the lens of geometry! Use the 19th installment in a 25-part module to apply the Pythagorean Theorem to solve real-world problems. Individuals sketch situations resulting in right triangles such as the...

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...

Investigate relationships between angles, arcs, and segments in circles. Pupils use geometry software to discover the relationships between angles, arcs, and segments associated with circles. Class members use similar triangles to...

Class members investigate rectangles on the coordinate plane. They determine the length of line segments in the coordinate plane with the same x-coordinate or same y-coordinate and then solve geometric problems involving perimeter...

Model geometric concepts through a hands-on approach. Learners apply similar triangle relationships to solve for an unknown side length. Before they find the solution, they describe the transformation to help identify corresponding sides.

And round and round the park we go! Given a description of an amusement park with the locations of three attractions connected by walkways, learners consider what happens when additional attractions join the mix by doubling the length of...

Is the gestation length of an animal a predictor of the average life expectancy of that animal? Learners analyze similar data for more than 50 different animals. They choose a data display and draw conclusions from their graphs.

Yummy! Use Twix candy bars to teach a lesson plan in comparing length! Learners will love this lesson plan and you will be addressing Common Core standards at the same time!

In this metric units of measurement worksheet, students read information about estimating lengths and masses, then solve 65 problems. Sample problems with solutions are included.

Learners measure the length and width of their desk using their hands. They measure the length and width of their desk. Students measure the length and width of their notebooks in the same fashion as they did their desk. They...

Students compare estimated lengths with actual lengths.

First graders compare triangle sizes, square sizes, and lengths. They use manipulatives of three varied sized triangles, squares, and strips to measure and compare relative size and length.

Third graders investigate the use of centimeters while measuring items with rulers which they construct. They examine the need for standard units of measure. They estimate the length of body parts before making the actual measurements.

Students determine the length of different whales using a rope marked off and color coded to each length. They create life-size scale drawings of whales on butcher paper.

Students measure the length and width of various sizes of envelopes. After comparing the envelopes, they explore the ratios, percentages, and rates. Students discuss postal rates and compare the cost of mailing items, delivery times, and...

In this metric worksheet, students examine conversion factors for length, mass, volume and area. Definitions of prefixes and metric abbreviations are identified.

In this ruler worksheet, 6th graders identify and complete 10 different problems that include reading various lengths of a ruler illustrated. First, they read each ruler shown on the sheet. Then, students write the length of the red line...

Students investigate parabolas as the shape of a telescopic lens.  In this Algebra I/Algebra II lesson, students explore the relationship between the coefficients of a quadratic function and the shape and position of the parabolic...

Fourth graders find the perimeter of a geometric shape by adding the lengths of the sides. They find the area of a square or rectangle by counting square units. Students use multiplication to find the area of a rectangle. They estimate...

First graders listen to a read aloud of Linda Williams, The Little Old Lady Who Was Not Afraid of Anything" before discussing Halloween. They measure pumpkins using chains of paper clips to find their length and width. Once they open the...

First graders participate in various activities dealing with measurement, length, volume, and temperature. They identify the need for standard units of measure, sort and classify objects, measure distances, and use a thermometer.

Fourth graders participate in an activity measuring length, weight and capacity. They incorporate physical movements to help them explore measurement.

In this unit students use the traditional tale of the gingerbread man as a context for ordering and comparing lengths. They compare the length of two objects directly, order three or more objects by length and select objects that are...
