Students collect and sort rocks based on visible characteristics.  In this statistics lesson, students determine adequate sample size and categorize rocks based on characteristics.  The book Everybody Needs a Rock is read to...

Students study the law of sine and cosine. In this pre-calculus lesson, students create a triangle and identify the different ratios of a non-right triangle. They use the properties of sine and cosine to solve.

Geometers calculate the area of plane surfaces using the formulas for the area of a square, rectangle, and triangle. They develop the formula for calculating the total surface area of two geometric solids: the cube and rectangular prism.

Students experiment to determine the effect of light on cyanobacteria movement. They graph the data of the experiment for further analysis. They watch a time-lapse video of cyanobacteria motility at a NASA website.

Graph polynomials and identify the end behavior of each polynomial function. The class differentiates between linear, quadratic, and other polynomial equations.

Students engage in experiences involving the mathematical concept of averages. After watching a video, students explore averaging through a variety of different methods.

Learners map their playground as if it were an archeological site. They locate objects on the playground and determine their location using coordinate points. A related lesson is Coordinate Grid: Mapping an Archeological Site.

Kindergarteners use worms, puppets or other props to practice counting to 100. First, they listen to a read aloud of Count Worms by Roger Hargeaves. A worm pattern is used to count to 100, with each segment of the worm...

Fourth and fifth graders study the Pythagorean Theorem and apply it to find the missing side of a right triangle.

Practice makes perfect! Learners estimate the least squares fit line for a set of data. They understand error involved in least squares fit lines, and solve application problems using least square fit lines.

Learners discover rules for single transformations, rules for composition of transformations, when a figure has transformation symmetry, and if a transformation is congruent to its preimage.

For this Archimedes worksheet, learners complete and respond to 4 different problems related to different triangles. First, they find the midpoint of each side of a given triangle. Then, students connect the midpoints with the opposite...

In the world of GPS, make sure your kids can still read maps and determine distances between locations. You will need neighborhood street maps, ideally of your class' home turf. Ask kids questions about different locations in relation to...

Young scholars explore how to solve any quadratic equation with a video about the quadratic formula. They then use the quadratic formula to solve a set of quadratic equations.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

First graders use unconventional units of measurement to discover the importance and need for a uniform unit of measurement.

Middle schoolers collect, organize, and analyze data while studying the Pythagorean Theorem, measure length and width of several rectangular objects, and compare the measured results to the calculated results.

Fourth graders practice measuring different objects in inches. Individually, they estimate the length of the same object in centimeters and then calculate the actual length. They compare and contrast their estimate to the actual length...

First graders use literature and hands-on activities with maps and globes to explain distance and tools used to measure distance. They select tools to measure various objects in the classroom, then apply those concepts to their map...

Students measure their shadows early in the morning, record direction of shadow, make marks in ground with chalk or tape, measure with ruler, and record results. Students repeat process at noon, and then later in afternoon. Students...

Students practice working with the metric system by measuring and recording the lengths of their smiles.

Second graders measure and grid their ideas for the new classroom floor plan. They create their own ideas for the classroom arrangement on grid paper. When they finish, they share their draft plan with their peers and with the teacher...

Young scholars identify the concepts of density, mass, and volume that define the property of a substance. They also determine that the properties of materials, such as, density and volume, can be compared and measured by using rulers,...
