Fourth graders identify lines of symmetry using reflections and then construct figures that have one or more lines of symmetry. In this symmetry lesson plan, 4th graders use sets of shapes, pattern blocks, a mirror, and more.

In this Boyles' Law activity, students answer volume questions given the temperature and pressure of various gasses. In addition to computing the mathematical volume of gas, students provide answers to questions regarding the story...

Learners explore scientific notation and the structure of the metric system.  In this middle school mathematics lesson, students read How Much is a Million? by David M. Schwartz to introduce learners to the need for scientific...

Students explore secants and circles. In this geometry instructional activity, students identify the properties of two and three dimensional shapes. They create arguments to prove the theorems are true.

Students measure the area using feet and yard. In this algebra lesson, students draw and manipulate shapes to calculate the area. They measure the relationship of area between the two units.

Pupils explore basic algorithms for addition, subtraction, and multiplication. They use models to demonstrate solving two-digit by two-digit multiplication. Students demonstrate vertical formats to solve multiplication problems.

Twelfth graders determine probabilities of real-life events such as life expectancies, winning a lottery ticket and the break-even premium. They apply how life-expectation tables are used to estimate the probability that an individual...

Students describe how several different objects magnify a provided sentence and decide if they are good magnifiers or not. They then write a sentence describing two properties an object must have in order to be a good magnifier.

Students are introduced to the problem by playing a guessing game of "I am a number, which is half of 6 and 6, what am I?" They explain their answers and see if anyone else had an alternate solution checking for reasonableness.

Students engage in an interactive Internet lesson covering the reasons and results of earthquakes. After reading eyewitness accounts and viewing animations, they use seismograms to measure and locate the epicenters. In an ongoing study,...

Students explore the concept of Mandelbrot sets and Julia sets. In this Mandelbrot and Julia set lesson, students use a function integrator applet to investigate two-variable function iterations. Students use Julia set and Mandelbrot set...

Students investigate speed, time and distance. In this algebra lesson plan, students utilize their knowledge of linear equations to solve problems related to time, speed and distance. This assignment is hands on using two toy race cars.

Students explore reasons why the dinosaurs became extinct, and the specific needs (habitat, environment, food) of individual types of dinosaurs.

Students examine the materials that are used to make space suits. They complete an experiment in which they test different materials in different colors to determine the best one for keeping astronauts comfortable. They analyze the data.

Students will learn about the respiratory system by comparing and contrasting models, building their own models, and giving one another feedback. Questions about familiar body systems can be useful in getting students to start thinking...

In this mathematics worksheet, 6th graders use a line graph to illustrate how a measure of data changes and explain their reasoning. Then they use a bar graph to compare pieces of data and a pictograph to compare data.

In this reasoning worksheet, 3rd graders analyze a sketch of a house and two feeder houses in order to answer 4 mathematical word problems related to distance.

Students explain why some colonists remained loyal to England during the American revolution. In this social studies lesson, students write a letter to an editor about their reasons for remaining loyal to England.

Students participate in a simulation activity involving the distribution of the world's wealth and power. The activity starts when 100 pennies, representing wealth and power, are spread on the floor and students must grab as many...

The sky's the limit of what you create when combining functions! The module begins with a review of transformations of parent functions and then moves to combining different function types using addition, subtraction, and...

Develop an understanding of the properties of exponents through this series of activities. This third lesson of 15 explores the patterns associated with the power property. Scholars expand the powers before applying the property.

Do ratios have values? The seventh lesson in a series of 29 introduces the value of a ratio. Pupils create associated ratios to a given ratio. They also describe the fraction associated to the ratio as the value of the ratio.

Examine the process of rotating images to visualize effects of changes to them. The fifth lesson plan of 18 prompts pupils to rotate different images to various degrees of rotation. It pays special attention to rotations in multiples of...

What in the world is the zeroth power? Examine the patterns of exponents as they apply to the zeroth power. Scholars apply the zero property to simple exponential expressions in this fourth lesson in a series of 15. The examples include...
