Taxi! Have your travelers figure out how far they can go in a taxi for $10.00. They must account for the mileage rate and tip in their calculation. They can set up a table or make an equation to solve for the exact mileage they can...

Sometimes you just want to know the cost of one apple. A fun interactive lets learners explore the unit costs of fruits, vegetables, and candy. It shows how ratios to express ratios symbolically and on a double number line.

Mathematicians answer five questions about percents, ratios, and proportions with help from an interactive graduated cylinder. Question types include multiple-choice, fill-in-the-blank, and discussion. 

If you made a doll version of yourself, how tall would you be? By using ratios and proportions, young mathematicians are able to answer this question. They actually create their dolls using clay, paper, or other materials.

Nobody wants to make Nana mad! Help Mr. Meyer fix the chocolate milk he prepared for his Nana using too many scoops of chocolate. Youngsters develop a problem-solving strategy that leads to the solution using ratios and proportions.

A watched printer never finishes—or does it? Engage your classes in a ratio and proportion task that asks them to predict how long it takes to print the numbers one through 88 on 88 sheets of paper. They use video to determine the rate...

Be an octave above the rest. A musician explains how to write music in different time signatures. An interesting resource continues to demonstrate ratios using the pitch of musical notes and hertz. Pupils use a pitch table and determine...

Young mathematicians study probability. In this math lesson, learners calculate odds, and convert those into percentages of probability. Fractions are also used, making this lesson quite rich in some of the more difficult conversions...

Discover how triangles are congruent based on their sides, angles, and proportionality. Learners explore the ways to determine similarity at their own pace, and then they practice afterwards with an assessment. 

Find a cheaper way to keep buses going round and round. Small groups use their knowledge of ratios and proportions to find ways to save money on school transportation. The teams determine the number of miles buses currently travel by...

Give a round of applause for completing the task. Scholars watch a video that shows an extremely fast clapper and a timer. The activity requires applying concepts of rates and proportional reasoning to estimate the number of claps in one...

Far out — plan a trip to space! Aspiring mathematicians steer a space vehicle through an asteroid field, calculate currency exchanges to buy provisions, and determine placement of charges to blow up asteroids. Along the way, they learn...

Explore the meaning of scale and proportion with a set of five activities that examines the topic from elementary through high school. The first lessons explore ratio by examining pictures of different sizes. The next three activities...

In this ratio and proportion worksheet, students solve 12 problems in which the ratios of shaded and unshaded tiles are calculated. Students use the provided pictures to write ratios.

For this ratio and proportion worksheet, 6th graders solve and complete 5 different types of problems. First, they determine the amount of money each person receives. Then, students calculate the recipe at the bottom of the sheet for 3...

Middle schoolers read a cookie recipe and complete a worksheet that asks them to establish ratios and proportions for various ingredients in the recipe.

Students figure out the mileage from one state to another using a map. In this map lesson, students look at the scale factor and turn it into a fraction. They measure the distance between two cities and use the proportion to find the...

Fifth graders explore ratios. Using models and real-world scenarios, they complete tables and generate comparisons. Pupils demonstrate multiple ways of writing ratios and describe the differences between ratios.

Students use M&M candies to show fractions, percents, and ratios. Individually, they complete a worksheet using their candies and solving equations of greater than or less than. They review their answers and strategies used as a...

Can you tell how tall someone is just by looking at their feet? In this activity, young mathematicians measure their height, arm span, and foot size, graph their findings, and answer questions about how these measurements are related....

Say cheese! Can your class take a great photo and size it to fit any need? A career and technology-centered lesson plan demonstrates the correct way to resize images in Adobe Photoshop. Scholars view a presentation and work individually...

Develop scales using tables. Pupils complete charts to show equivalent scale factors before using the completed tables to determine the sizes of scale drawings. They finish the lesson and demonstrate their understanding by completing a...

A different-than-normal problem that allows learners to practice their reasoning to find an answer. The problem bases itself off a graph drawing of a store that needs to install security cameras. The challenge is to find which placement...

Make young mathematicians' dreams a reality with this fun drawing project. Given the task of designing their dream home, students create drawings and physical models that demonstrate their understanding of proportion and scale.
