Examine ratios and proportions in several real-world scenarios. Children will calculate unit rates, work with proportions and percentages as they plan a party, purchase produce, and take a tally. This lesson plan recommends five...

Investigate the growth rates of alien animals. Pupils study fictional animals from another planet to determine how much they grow per year. The investigators plot the growth of their animals over a period of time and then compare...

What an impressive task it is to make dental impressions! Pupils learn how dentists use proportional reasoning, unit conversions, and systems of equations to estimate the materials needed to make stone models of dental impressions....

Fourth graders use colored beads in two problems and explore the use of proportional reasoning as a problem solving method. Working Students, in groups, explain their reasoning strategies orally, and through drawings.

Question: What do rectangles and bathtub volume have in common? Answer: Linear equations. Learn how to identify situations that have constant rates by examining two different situations, one proportional and one not proportional.

Students explore the relationship between two variables. Students measure their arm span and height. They gather this class data to design a scatter plot. Students interpret the meaning of individual coordinates and the overall graph....

Show your classes the importance of mathematics in something as simple as bicycle design. The final lesson in the six-part STEM series has each group research a different aspect of the bicycle. Learners use mathematical formulas, linear...

Students create a mini city using proportions that fit a model human they construct using tin foil. They plan the city including a library, sports arena, living spaces, parks and businesses. When constructing the paper buildings, they...

Students solve problems with fractions without using a calculator. In this algebra lesson, students practice reducing, converting, adding, subtracting and multiplying fractions. They apply the use of fractions to the real world.

Students make predictions based on survey results. They calcuate sample proportions. Students estimate the number of voters in their district preferring the democratic candidate using their sample results. They review sample proportions...

Students relate algebra to real life scenario. In this algebra lesson, students design a plan to help traffic flow smoothly using velocity and speed. This assignment is done using Microsoft Excel.

Young scholars examine population growth and collect data. For this statistics lesson, students create a scatter plot to represent the different species found in the water and are being harvested. They graph their data and draw...

Young scholars explore graphing. In this graphing lesson, students sort Skittles candies and use the color groups to create a bar graph. Rubrics and extension activities are provided.

Students construct a bar graph with a given set of data. They calculate the ratio and percent of the data. Students discuss alternate ways of graphing the data as well as multiple strategies to approach the task.

Students create a 3D vector field map of an electric field. In this physics instructional activity, students measure the voltage inside an aquarium with water. They present their findings and map to class..

Young scholars 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.
