Students participate in a lesson that investigates Newton's Second Law of Motion. They conduct an experiment of observing balls that are rolled down a ramp. The lesson includes background information for the teacher for preparation and...

Steel is an example of homogeneous mixture, also called an alloy, which is made of iron and carbon. The presentation introduces learners to elements, compounds, and mixtures. They explore their similarities and differences, and then take...

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.

A quick problem to test your middle schoolers' knowledge of dividing with decimals. Also a good practice of unit rates, they must compute the cost of one gallon of gas when given the total amount for a fill up. Can be used as a preface...

Give your future household repair specialists a real-life chance to apply the concepts of ratio and proportion. Using a scale drawing, they calculate the missing dimensions of two walls of a compound-shaped attic. They then figure how...

Have your aspiring contractors compute the length of two walls in a compound-shaped attic when given a scale drawing of it and the other dimensions. They find the area, determine the number of rolls of insulation they will need to...

Setting financial goals is a common occurrence in middle school that your learners can practice using this activity. They will be able to solve for how many hours Seth needs to work to save up for a skateboard, helmet, and trip. The...

Exponential growth is modeled by learners as they analyze and interpret the data presented in this real-life scenario centered on the destructive invasion of the Giant African Land Snail. Learners get a touch of history and practice...

Ever wonder how a butcher creates the different types of ground beef? Young mathematicians explore the methods butchers use to create their desired ground beef quality. Given a combination of two types of meat with varying...

Eighth graders identify that a ratio is a comparison of two numbers and that a proportion is an equation that equates two ratios. They identify the extremes and means of proportions, as well as the product of the extremes equals the...

Third graders investigate ratios and rates.  In this third grade mathematics lesson, 3rd graders identify equal ratios and rate and test for proportionality.  This lesson is created to be use in conjunctions with a particular...

students are the opportunity to enhance their computation skills using real life statistics associated with the Space Shuttle. Skills emphasized include working with fractions, decimals, percents, ratios and proportions, comparing units,...

Eighth graders follow a recipe, focusing on the concepts of ratio and proportion, to mix a batch of icing. They decorate cupcakes in the form of a pumpkin.

Eighth graders measure height and shadow length of other students on a sunny day and develop a ratio. They apply the ratio to other students and objects using shadows to determine height.

Students test their knowledge of the Wright Brothers and their aircraft, and compute ratio of two numbers to determine the ratio between wing span and length of aircraft.

Students work together to build a simple gear train. They record their observations as it gains speed and how the gears rotate. They develop rules about gears based on these observations.

Sixth graders practice the conversion of percents and fractions. They focus on the fact of both fractions and percents are part of a whole. In the independent practice the students also work with solving proportions.

Ninth graders find the height of every day objects using techniques learned through postulates that allow triangles in a problem to be similar. They calculate the length of a missing side and solve proportions.

Students solve and verify the solution for unknown measures. In this geometry lesson plan, students identify the properties of circles. They use the arc, angle and segment relationship to find the missing measures.

Students solve problems involving ratio and proportion. In this algebra lesson plan, students analyze the currencies found in different countries. They create formulas to convert between the different currencies and use ratio and...

Students calculate the distance they can travel on a tank of gas. In this algebra lesson, students use ratio and proportion to solve word problems. They graph their results and discuss their findings with the class.

Student identify the solution using geometric mean. In this geometry lesson, students create right triangles where the altitude of the triangle is the side containing the right angle. They modify shapes using Cabri software and observe...

In this geometry worksheet, students use the properties of similar polygons to find the indicated missing length or the scale factor. The two page worksheet contains twenty-two questions. Answers are included.

In this algebra worksheet, students rewrite word problems using algebraic symbols. They solve for the amount of population or money over a period of time. There are 10 questions with an answer key.
