Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

Having problems with proportions? Then solve these proportion problems with an exercise that asks learners to first individually solve a set of problems involving ratios and proportional reasoning. Groups then discuss provided...

Proportions, proportions, everywhere. Class members complete an assessment task solving problems involving proportionality. They then complete an activity classifying given situations as proportional or non-proportional.

Students convert their physical models of a playground from a previous lesson into a map of the playground that includes a scale and key. They examine and discuss examples of maps, view an image to map photo essay, and create a map using...

Compare information from a US population cartogram and a standard US map. Learners draw conclusions about population density by analyzing census data a population distribution. They discover that census data is used to apportion seats in...

Students explore the distance formula using real world data from nonviolent marches for social change.  In this secondary mathematics lesson plan, students investigate the marches of Gandhi and King using maps overlaid with a...

Learning about proportions through measuring and mapping distances is the focus of this real-world math lesson plan that doubles as an activity. Mathematicians complete a course designed to measure and map locations in order to put the...

Drive or take the school bus? Class members determine the amount each student would have to pay in a carpool situation. They then evaluate  the cost in a set of provided examples. I think I'd rather take the school...

Students explore the relationship between a scale drawing and actual distance. In this mapping lesson plan, students use an amusement park map to determine distances and what they would be like in real life.

Third and fourth graders are introduced to the concept of map scale. Using an illustration, they discuss if it shows the actual size of the object and why scale is used to represent areas. They use some items in the illustration to...

The key to understanding is making connections. Scholars explore angle dilations using properties of parallel lines. At completion, pupils prove that angles of a dilation preserve their original measure. 

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...

Eighth graders solve problems using proportions with scaled drawings. They work with maps and blue-prints discussing scales and plans and examine different polygons and figure out the scale factors or proportions they have been changed by.

Eighth graders use ratios and proportions to solve real-life problems.  In this using ratios and proportions to solve real-life problems instructional activity, 8th graders estimate the cost of a road trip.  Students estimate...

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.

Students investigate the purpose of map scale and how it is used to measure the distance and the size of objects.

Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup...

Students review their physical models of the objects on their playground at school. Using the model, they convert it into a map with a scale and key. To end the lesson, they use the map to locate different objects and measure the...

Sixth graders plan trip for family of four, and choose best travel plan by studying maps, considering different routes, and visiting Web sites to get airline and travel schedules.

Seventh graders discuss the elements of maps and using basic linear measurement. They calculate the distance between the cities and create a simulated journey around New Mexico using a road map. They write out the directions for their...

By making the following changes to the roads, we can prevent several accidents. A multiple-day lesson plan prompts pupils to investigate accidents in a small town. Pairs develop a proposal on what to do to help reduce the number of...

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Sixth graders plan a trip for a family of four choosing their travel plan by studying maps to decide upon a route and visiting Websites to get airline and travel schedules. They use ratios and proportions as well as converting fractions...
