Middle schoolers identify and interpret various ways of expressing probability as a decimal, fraction, percent, or ratio. They solve problems based on probability as they apply to real world applications.

Young scholars play games to reinforce math concepts. For this geometry lesson, students identify the probability of an even occurring. They find the vertex of a parabola and Euler and Hamilton examples.

Learners solve for the different ratio and proportion of a problem. In this geometry lesson, students show their knowledge of how to solve proportional relationships. They convert between percent, decimals and fractions.

In this Algebra I worksheet, students solve problems in which they differentiate between a ratio and a rate.  The nine page worksheet contains explanation, worked examples, and seventeen problems.  Answers are not...

In this similar figures learning exercise, students complete a chart calculating the perimeter and area of four rectangles and then compare the ratios. There are 4 questions. 

Seventh graders study ratios, scale and distances according to a three dimensional model.  For this exploratory lesson students create their own constellation and prepare an oral presentation that describes their model. 

Seventh graders construct a three dimensional model of a constellation. For this constellation lesson, 7th graders make a blueprint for a scale model of the constellation and create their models. They present their models to the class.

In this reducing ratios worksheet, students reduce or simplify 8 ratio expressions by finding common factors for the two numbers.

In this ratio and proportion worksheet, students explore example problems. Afterwards, they read story problems and use ratios and proportions to find the solution. This three-page worksheet contains six multi-step problems,

In this proportions worksheet, 8th graders solve and complete 10 different problems that include difficult word based proportions. First, they solve each proportion as described. Then, students write their answer on the line provided for...

In this independent events probability worksheet, students solve 10 different problems that include determining the probability of certain events described. First, they determine the probability of selecting at random a number divisible...

Students understand that a spreadsheet can be used to find the best scale to use in a model. They place the distances of the planets of the solar system to the Sun in one column of the spreadsheet. Students try different scales so that...

Learners calculate the height of a tree or flagpole. They measure the shadow of the tree or flagpole and the length of a shadow of a meterstick. Using similar triangles, calculate the heigh. Devise two additional ways in which to measure...

Students work in cooperative groups to find the actual measurements of an historical building/landmark. Then they use ratio and proportion to figure the measurements that might be used to create a scale model of the structure.

To practice multiplying fractions and mixed numbers, students choose a starting whole number and multiply it by a mixed number. Students then answer a number of questions about ratios for different problems. This worksheet is intended...

Students explore ratios and their relationships to fractions. They explain the process of identifying ratios and describe their comparison. Students write ratios as fractions and by using colons. They convert the ratios to percents.

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...

Eighth graders examine probability. Students read real life situations involving math. Upon completing probability problems, they express their answer as a fraction, decimal or percent.

Ninth graders investigate the concepts of ratio and proportion.They solve examples with the teacher for ratios and proportions. A basic fraction review is used for a warm up in this lesson. The primary focus of the lesson appears to be...

Pupils examine concrete samples and guess their strength. They determine the correlation between concrete strength and the cement to water ratio that was used in making each sample. They make a quality concrete based on their findings.

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.

The CyberSquad tests which broom can travel the furthest in five seconds in this video from Cyberchase.

The interactive assessment examines ratios, proportions, and percents. Students complete 14 questions created by Glencoe. Hints and solutions are included.

The interactive assessment examines ratios, proportions, and percents. Students complete 20 questions created by Glencoe. Hints and solutions are included.
