Students determine the most equitable way to share space and cost between three schools for a fictional science fair. Given a diagram, a word problem, and a data set, students analyze and explain the best way for all schools to share...

Eighth graders investigate properties of circles.  In this eight grade mathematics lesson, 8th graders apply proportional reasoning to data gathered with “Google Earth” to calculate equatorial and polar circumference of the...

In this ratios worksheet, students solve 22 problems in which equivalent ratios are found or ratios are expressed in simplest form.

In this geometry activity, 10th graders solve a problem relating to the length of a line segment.  The location of the points on the segment is given in terms of ratios.  The one page activity has one problem with the...

Young scholars solve algebraic proportions. In this algebra lesson, students convert between fractions, percents and decimals. They solve problems using the distributive property.

In this direct and inverse variation activity, 9th graders solve 10 different problems that include various situations in variations. First, they find the constant of proportionality when given each variable measure. Then, students...

In this percent application activity, students solve word problems containing concepts such as percent, proportions, sale price, discounts, interest, commission, tax, and more. Students complete 11 problems.

In this geometry worksheet, students differentiate between similarity and proportion. They use scale factor as they solve for the different proportions. There are 15 questions.

In this identifying similar triangles activity, 10th graders solve 6 different types of problem that include identifying and comparing similar triangles. First, they identify the three ways that determine whether two triangles are...

In this unit rate worksheet, students read story problems and determine the unit rate. They set up equations to solve proportion, percent and mixture problems. This one-page worksheet contains seven story problems.

Knowing how to scale a recipe is an important skill. Young mathematicians determine the amount of ingredients they need to make a certain number of truffles when given a recipe. They determine a relationship between ingredients given a...

Remodeling projects require more than just a good design — they involve complex fractions, too. To determine whether a tiling project will fit within a given budget pupils calculate the square footage to determine the number of...

Upper graders will solve equations using order of operations, and create equations that to play a fun math bowling game. They will bowl using dice to practice operations. Extensions are also included.

students investigate the concept of using a ratio in the work of construction and solve problems using real life applications. They read descriptions of how various types of construction professionals use ratios on the job. The lesson...

In this statistics and probability worksheet, young statisticians solve and complete 13 different problems related to probability, percentages, and normal distributions. They consider data models, assumptions about the models, and find...

In this similarity worksheet, students solve and complete 7 different problems that include determining various dimensions of mirrors shown. First, they find the length of the diagonal of the large mirror in the diagram. Then, students...

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.

Using the concept of a candy vending machine, young mathematicians explore the sugar ratios found in different types of candy. Using the provided information, class members calculate and compare different ratios in...

Scholars view the video, "Donald Duck in Mathmagic Land," and discuss examples in nature which have proportions of the golden ratio. They measure and record different body lengths from a worksheet and convert the ratios to equivalent...

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...

Emerging statisticians develop the ability to make inferences from sample data while also working on proportional relationships in general. Here, young learners examine samples for bias, and then use random samples to make...

Visualize methods of finding percents. Classmates find a percent of a quantity using two methods including a visual model in the 26th lesson in a series of 29. By the end of the lesson, scholars find percents given a part and the whole...

Once learners realize what direct variation is, they see it's just a type of linear function. The lesson poses a general question that leads to the creation of the y = kx formula. The resource includes discussion prompts and ideas for...

If members of your class wonder where they can use the math they learn in middle school, let them discover the answer. Learners apply geometry concepts of scale and measure to calculate the costs of framing a house addition.
