Students differentiate the types of cryptosystems and use them to communicate privately. In this algebra lesson, students use substitution and transposition to identify the cryptographs. They send and receive cryptograms as they try...

Students estimate and calculate the distance of a shape. In this algebra lesson, students differentiate between a horizontal distance and it's reflected image. They measure the reflection and the point starting at the eye of the observer.

Use a box of raisins to help introduce the concept of data analysis. Learners collect, analyze and display their data using a variety of methods. The included worksheet takes them through a step-by-step analysis process and graphing.

Learners are introduced to the concepts of the normal curve, skewness and the standard deviation. They discuss how the normal distribution has been used and misused to support conclusions.

Young scholars generate a list of numbers then classify them into groups of single digit and double-digit numbers. After listening to a children's book about double-digit addition, they work with tens and ones blocks to solve...

Graph inequalities and discuss the difference in their slopes. Learners observe rate of change as they compare linear, quadratic, and cubic functions.

Fourth graders find the range, mode, median, and mean for each of the data sets (height and shoe size). They discuss which measure of central tendency for each data set best represents the class and why. Students graph the shoe size and...

Twelfth graders examine the legislative process of enacting federal income tax laws. They conduct research and report on the Federal Migratory Waterfowl Stamp (Duck Stamp) Act of 1934.

Students, using manipulatives, determine how many different ways there are to arrange 3 and 4 objects. They organize and record their arrangements. Students investigate the pattern generated by 3 and 4 objects, they predict how many ways...

Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.

Students apply probability to real life situation. In this statistics lesson, students play poker and make predictions on what hand they will get next. They apply their knowledge of how probability works to make their predictions.

Students study about mathematicians' notion of fairness in games of chance. They work in pairs to perform three different experiments using macaroni and paper bags. They record their results on charts and discuss the fairness of the games.

Students create a floor graph and then interview their classmates to create their own graph.

Students explore the definition of agriculture.  In this Language Arts and Social Studies instructional activity, students read an article on products that are produced in agriculture, then they complete a vocabulary assignment and...

Reading, a math game, and a simulation activity provide the engagement on a lesson about seeds and crops. Learners in grades two through four read an informational passage about crops, seeds, and farming. They highlight important...

Learners compare and contrast the various types of rocks on each continent. In groups, the calculate the rock ages and types to determine if the continents, in their opinion, were joined at one time. They develop two imaginary...

Students learn about the four biochemicals that are important biologically. In this biochemicals lesson plan, students identify the four major groups of biochemicals including carbohydrates, proteins, lipids and nucleic acids. They are...

Build boxes using unit cubes to compare surface area and volume. The group performs multiple experiments to determine properties of volume, such as if it makes a difference which order the dimensions are multiplied in. Extensive...

Statisticians analyze a data set of student IQs by finding measures of central tendency and dispersion such as mean, median, mode, and quartiles. They practice using a graphing calculator to find the values and analyze box plots and...

Students explore how the population decreased in native cultures.

Can you name the three planets with rings in our solar system? Everyone knows Saturn, many know Uranus, but most people are surprised to learn that Jupiter also has a ring. The third in a series of six teaches pupils what is around...

There is more than one way to measure an amount, as learners discover by applying multiple measurement tools in these activities. Centimeter cubes, cylinders, beakers, and measuring cups are used to find the volume of regular and...

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Students are introduced to the component's of Ohm's Law. In groups, they practice their problem solving skills by reviewing problems solved earlier. They participate in activities that help them gather information on the importance of...
