Give plants the best place to grow. Given constraints on plant spacing, pupils design a raised bed garden using graph paper, then calculate the perimeter, surface area, and volume. They use the provided costs of lumber and soil to...

Make sure there is enough ice cream on hand. Learners try to find out how much ice cream to buy for a sports event. Scholars use a pie chart showing the percent of a sample of people who like different flavors of ice cream. Using the...

Eighth graders explore the weapons of the Aboriginal people.  In this eight grade math/science lesson, 8th graders collect and analyze data regarding the speed and distance of a dart thrown with an atlatl.  Students choose the...

Learners explore the concept of percentages. In this percentages lesson, students find the percentages of various colored m&m's in their bags. Learners find the cost of items before and after a discount. Students use proportions to...

Students compare prices and determine percent increases and decreases of items in order to make wise purchases. In this percent increases and decreases lesson plan, students calculate the amounts based on grocery store ads.

Eighth graders discover the relationship between speed, distance, and time. They calculate speed and represent their data graphically. They, in groups, design a ramp for their matchbox car. The goal is to see who's ramp produces the...

Learners calculate the size of a mummy case and its contents using ancient Egyptian measurements.

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.

Learners use cross-multiplication to find the unknown respiration rate of an astronaut. In this multiplication lesson plan, students also use the same process to find missing values in proportions.

Students determine the length and width of leaf samples to the nearest millimeter and the circumference of trees. They participate in a discussion about the importance of collecting specimens carefully. They compile accurate...

Students work on different mathematical skills that align with state standards. The skill of problem solving is done with reasoning and communication is made to students through solid brain connections to the math concepts.

Students are involved in a cooperative learning environment that analyzes fractions, ratios to time and distance, equivalent fractions and numerical relationships and expressions in quantitative problems. They take notes, relate...

Ninth graders explore the concept of ratios. In this ratio lesson, 9th graders construct a to scale time line that starts at the beginning of time. Students determine the correct placement of big events in time such as when the dinosaurs...

Middle schoolers explore the concept of the golden ratio. In this golden ratio lesson, students measure objects to determine if their measurements fit the golden ratio. Middle schoolers calculate the average measurements of the class.

In this math activity, students will take home a letter to their parents explaining that they are studying Chapter 10: Ratio, Proportion and Percent. Then students will complete a homework activity in which they ask family and friends...

Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

Students conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain how...

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

Students create scale models of Earth, the Moon, and the distances within the universe. Working in groups, they construct their models of Earth and the Moon on a scale of 50:1 and calculate how far apart to place their models. They...

Learners estimate the total number of species in Ecuador using the capture/recapture method. They collect data about each species and act as members of a science expedition to determine the total number of species by using mathematical...

Explore how resizing an object affects its area. The set of lessons challenges young mathematicians to design a mascot for electronic devices. These designs undergo resizing to determine how scale factors of dilation affect area.

Setting financial goals is a common occurrence in middle school that your learners can practice using this activity. They will be able to solve for how many hours Seth needs to work to save up for a skateboard, helmet, and trip. The...
