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,...

Students discuss the concept of "aspect ratio" of the Helios Prototype. They find real life objects that are taller or shorter than them by a certain amount. They practice with ratio and measurement.

Fifth graders explore ratio problems. They study how to solve ratio problems using simple algebraic equations. Students use equations to represent practical situations and solve equations.

Young scholars look at ratio, what it means for numbers or objects to be in a given ratio, and how ratios and fractions are related. They write and solve story problems which involve whole numbers, using addition, subtraction,...

Students discuss scale diagrams and maps as well as the use of spreadsheets to find the best scale to use in a model before practicing scale and ratio problems on their own.

Students research items that can damage hearing. They explore statistics about the decibels of certain objects. From the information collected, students create a bar graph. They formulate ratios to determine what sounds are harmful to...

Students analyze and integrate mathematical concepts within the context of social studies. They gather, present and analyze information on a bar graph, pie chart, etc. Students compute ratios. They demonstrate that ratios have real-world...

Tenth graders answer a variety of problems based on similar triangle and learn about the rule of thumb. They will test the rule of thumb by estimating the distance to an object in the classroom.

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.

Students design and build a snowplow using LEGO materials. They compete in an Engineer's Challenge to clear a path through Styrofoam peanuts.

Learners 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.

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 engage in a lesson which provides them with a concrete introduction to the concept of ratios. They demonstrate the ability to create ratios with given substances - peanut butter and jelly.

Students calculate the stride length of a walking or running animal. They use scale models of dinosaurs to calculate the leg and stride length of the animals.

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

Students view projections of dinosaurs in order to comprehend their true size.

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.

Second graders use knowledge of measurements and ratios to mix various combinations of liquid starch and glue. They chart their ratios, make observations, and write a summary of the activity. They mix their own batch of Crazy Putty to...

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 use critical thinking skills to solve word problems using ratios that allow them to compare humans to ocean animals.

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Students access web site and record various population statistics pertaining to a county in the USA of their choice. They use this data to set up and solve ratios. They compare data to make meaning of the numbers.

Third graders attempt to determine the height of a telephone pole or tree without climbing to the top.
