Fourth graders find change for an amount given. In this real life subtraction lesson, 4th graders use an advertisement to select items to "buy." They figure out how much money they would pay the cashier and how much money they will get...

Students secure information online using cryptography. For this algebra lesson, students use RSA technology to encrypt information on the internet. They use modular reduction of natural numbers to understand prime number theory.

Pupils analyze graphs for specific properties. In this algebra lesson plan, students solve equations and graph using the TI calculator. They find the different changes that occur in each graph,including maximum and minimum.

Students collect real data on sound. In this algebra activity, students use a CBL and graphing calculator to observe the graph created by sound waves. They draw conclusion about the frequency of sound from the graph.

Students recognize patterns and sequences in numbers. In this geometry lesson plan, students create rules to define the sequences and patterns they obsere. They translate coded messages as they dicuss navigational terms.

Students discover the formulas for calculating distance. In groups, they solve equations determine the distance in a specific amount of time. They record their answers in a chart or graph and compare them with their classmates.

Students use a variety of strategies to figure out the cost of baseball tickets. They use a combination chart, notebook notation, etc. to find the cost of their family to attend a Cardinal's game in St. Louis.

Students use Geometers SketchPad to find the area and perimeter of several shapes. For this geometry lesson, students determine area of rectangles and progress through irregular polygons. None of the referenced worksheets are included...

Students are introduced to the given problem and describe in their own words the situation represented in a bar chart and tally chart. They then use a bar chart and tally chart to make sensible predictions.

Eighth graders display the outcome of given events by creating and reading tree diagram. They explain the relationship between addition and multiplication.

Ninth graders discover what it means to "brainstorm." They explore a given simple number pattern and then, working in groups, brainstorm more complicated number patterns. They display them around the room and then solve the number...

Students work in groups to research clocks and practice telling time. In this telling time lesson, students use the computer program ProQuest to study circles, including radius and diameter, and practice drawing circles using a compass....

Second graders conduct survey and sort data according to categories, construct bar graph with intervals of 1, and write a few sentences about their graphs.

Students use data from the Rossi X-ray Tiiming Explorer (RXTE) satellite to analyze and graph.

Students assess some common inherited traits which are easily observable and note their phenotype for the trait. Students compare their phenotypes to those of their parents and attempt to describe the pattern and manor of inheritance.

Seventh graders participate in several learning/research stations in which they view artwork from various countries of the Eastern world and collect information on the populations of the Eastern countries. They then use this information...

Young scholars explore geometric shapes using pattern blocks. They use specific shapes to fill in triangles, color-in their solutions, and discuss the results with a partner.

Students practice performing various accounting functions. Given analysis records, they prepare cost and revenue analysis based on specific criteria. They complete handouts and review their answers as a class. They also discuss the...

Students complete activities to study the concept of place value notation. In this place value instructional activity, students use cards for the days of the month that only number from 1 to 9. Students find a subtraction pattern to...

Students use a word processing program to make patterns.

Students use the Internet to do research on the roller coasters at Magic Mountain Amusement Park. They must use mathematical formulas to calculate the highest and fastest coaster at the park.

Fifth graders use a scientific calculator to practice finding equivalencies They discuss the possible uses for the scientific calculator. They experiment with other basic functions using the calculator.

Pupils watch the teacher demonstrate on an overhead projector how to graph various equations before the students try them on their own. They start with pencil and paper; once they grasp the concept they move on to punching in the...
