Pupils build a working definition of regular fractal, look carefully at the concepts of dimension and scale, and are introduced to logarithms. They solve simple exponential equations for the exponent both by trial and error and using logs.

Students determine the size of the population at a given time. They calculate the time at which the population will be a given number. They observe how the population grows at the rate that is directly proportional to the number of...

Middle schoolers build a working definition of a regular fractal, they measure the concepts of dimensions and scale, they explore the concept of a logarithm and they attempt to solve simple exponential equations for the exponent both by...

Students practice identifying fractional parts represented in pictures and phrases. In this fraction lesson, students determine the proportion represented by common time and money phrases such as "3 hours in a day". Students match their...

For this ratios worksheet, 6th graders solve and complete 3 different types of problems. First, they divide each amount shown in the ratio of 2 to 3. Then, students explain why the amounts worked out to be whole numbers.

Young scholars explore the concept of Venn Diagrams through word problems. In this Venn Diagram lesson plan, students solve word problems about groups of people using Venn Diagrams. Young scholars use survey results about MySpace and...

Students represent relationships between variables by writing, creating, and solving linear equations, and using tables and graphing.

Fourth graders estimate the average traveling distance to a city of choice with the help of an internet site. They determine the amount of time it will take to travel there at a speed of 65 miles per hour. Students set up a proportion to...

Young scholars investigate the concept of using different types of presentations to help solve mathematical problems. They research the use of illustrations to help understand data and its interpretation in a graphing format. Students...

In this percent equations instructional activity, 7th graders translate word problems to number equations and then solve them.  They write proportions to solve percent equations.  This two-page instructional activity contains 9...

Students construct using Cabri software. In this geometry lesson, students convert between units and apply the correct measurements to build objects. They create the room virtually and manipulate the shapes to the desired measurements.

In this population worksheet, students read word problems relating to population growth. They write the problem as a differential equation, create models and graphs of the solution. This three-page worksheet contains 10 multi-step...

Seventh graders explore the skill of finding the increase and decrease of a quantity. Calculating the increase and decrease is covered by a percent. The proporition for finding a percent is also part of the lesson.

Students measure using tools they have made. In this algebra lesson, students measure the height and distance using non-traditional measuring methods. They apply their findings to algebra and trigonometry properties of measurements.

Your class will use a TI calculator to drag vertices of rectangles and triangles to observe what happens to ratios of pairs of sides within each figure. They will apply the definition of similarity to identify similar shapes. The...

Students compare prices and determine percent increases and decreases of items in order to make wise purchases. In this percent increases and decreases lesson plan, students calculate the amounts based on grocery store ads.

Middle schoolers examine and compare traits of humans and crocodiles.  In this crocodile instructional activity students use a ratio to estimate the height of a person and compare that to a crocodile. 

Student are assigned one of the sections on whole numbers. After reviewing the content, they teach their assigned sections to other class mates. They publish their findings on a PowerPoint slide show to use when they teach their section.

Computing class members encounter use a digital learning tool called The Fraction Bar to multiply fractions with whole numbers. They do so by finding a given fraction of a number either on a number line or by calculating the answer with...

Eighth graders discover the relationship between speed, distance, and time. They calculate speed and represent their data graphically. They, in groups, design a ramp for their matchbox car. The goal is to see who's ramp produces the...

In this similarity worksheet, students determine the length, area and volume of similar figures. This three-page worksheet contains explanations, examples, and 20 problems. Answers are provided on page three.

Students construct a bar graph with a given set of data. They calculate the ratio and percent of the data. Students discuss alternate ways of graphing the data as well as multiple strategies to approach the task.

For this Geometry instructional (work)sheet, learners are instructed on how to find the geometric mean.  Students are then shown how the geometric mean is applied to proving similar triangles.

Students, in groups, measure and record each other's height. They identify measurement conversion methods and use online resources to convert measured heights to multiple systems.
