Show scholars the importance of recognizing a normal curve within a set of data. Learners analyze normal curves and calculate mean and standard deviation.

Reflections are the geometric mirror. Pupils explore this concept as they discover the properties of reflections. They focus on the coordinates of the reflections and look for patterns. This is the third lesson in a seven-part series.

Like all of the Problem Solving units, this one aims to introduce students to the underlying ideas of mathematics through a problem. The problem here requires a knowledge of arithmetic and the use of some algebra. In this unit we see how...

Students explore the concept of addition as used in the subject of Algebra while reviewing the different methods using a number line. The lesson includes examples for students to use for scaffolding for group work or whole class...

Sixth graders measure circumference and diameter to the nearest eighth of an inch, record measurements on a spreadsheet, and use the internet to complete a "scavenger hunt" of facts concerning pi.

What do you do with a difficult-to-factor quadratic expression? This lesson provides the answer. Pupils learn a grouping strategy to help factor trinomials. When guess and check seems too tedious, this method is the "works every...

High schoolers create a mathematical formula to help plan ration supplies for a polar expedition. Using basic algebra skills, students identify the variables in planning for rations. They create an equation to help plan the expedition....

The Egyptians used unit fractions to describe all other fractions. Your class will rewrite rational expressions in order to deduce information about rational numbers. The activity starts with specific fractions, guides you through a few...

First graders incorporate language expressions, such as first, then, and together into a story and write the math equations that they represent. Concepts for the process of addition are developed using manipulatives, modeling, and...

Students use classified ads to select a career. In this math lesson, students convert the listed salary to an hourly, yearly, weekly and monthly rate. Students explain the process they used to find the various rates.

Discussion doesn't always need to be spoken. Before you begin The Tempest by William Shakespeare, have kids connect their ideas and experiences to central questions of the play with a silent discussion activity. Once they have...

Ninth graders review the information that they have already learned with regard to linear equations and graphical representations. They then assist in combining equations with a graphical element and complete various graphs with this...

Students identify and use appropriate formulas to find surface areas of solid figures, practice using formula sheet to solve textbook problems, construct solid figures of given surface area using TABS+ software program, and use Internet...

Students investigate different online tutorials as they study graphing. In this graphing lesson, students apply the concept of graphs cross curricular and use it to make predictions. They define the purpose and theories behind graphs.

Students participate in five center activities in which they construct three dimensional objects using cubic centimeter manipulatives such as sugar cubes and toothpaste boxes. They determine the volume of the objects. They build a model...

Students sort medications by likeness and use. They compare and contrast using a Venn Diagram, and find the differences and commonalities of over the counter and Rx medications.

Seventh graders analyze responses to different types of problems. Using pictures and diagrams, they explore and model the division of fractions. Students examine situations that call for division whether with the whole numbers or with...

Students (Resident assistants) enter their jobs in college and university housing environment with a variety of skill levels in problem solving. Because of the live-in nature of the position, however, most of the problem solving skills...

Students explore problem solving.  In this middle school mathematics lesson, students investigate the five-step approach to problem solving.  Students solve word problems by employing the five-step process.

Students develop the skills of problem solving and logical analysis. The conditions of when two subtraction sums are equal is examined to develop other skills like practicing arithmetic in context.

Learners explore problem solving strategies. Given real life problems, students examine the sum of consecutive strings of whole numbers. Learners use diagrams and sequencing to solve problems. Students justify their mathematical...

Second graders participate in a Scavenger Hunt to find out how long 1 cm is. They then find 10 objects that estimate to be 1 cm in length and record their findings on the table provided and check their estimates using a ruler.

This unit encourages students to assess the validity of a set of statements and then plan and carry out investigations to find out whether the statements are true. Students then carry out statistical investigations of their own.

Students examine gravity, mass, and friction. In this speed and motion instructional activity, students investigate how straight line motion is impacted by gravity, mass, and fiction as they participate in a hands-on activity.
