Nurture a love of math and farming at the same time. Pupils apply geometry concepts, such as surface area and volume of three-dimensional shapes and similarity ratios, to farming contexts. They consider the dimensions of bales of hay,...

If you made a doll version of yourself, how tall would you be? By using ratios and proportions, young mathematicians are able to answer this question. They actually create their dolls using clay, paper, or other materials.

Students use the key accounting ratios for profitability, liquidity and performance and calculate appropriate ratios. They interpret the results of the accounting ratio used.

After elections, the total amount of votes is not specified but the ratio of votes is. Your learners' job is to determine the fraction of votes John received above half of all votes. The problem can be solved abstractly or by other...

Analyze and graph oxygen isotope ratios in coral samples in relation to the distance from the outer skeleton edge. Compare the data to the mean monthly water temperatures. Uncover whether or not there is any correlation. In addition to...

A survey of Mendelian genetics is presented through this handout. Biology prodigies answer questions about the Law of Segregation, phenotypic ratios, and dominance. They define genetics vocabulary terms and describe various genetic...

In this ratio and proportion worksheet, students solve 12 problems in which the ratios of shaded and unshaded tiles are calculated. Students use the provided pictures to write ratios.

In this ratio and proportion worksheet, 6th graders solve and complete 5 different types of problems. First, they determine the amount of money each person receives. Then, students calculate the recipe at the bottom of the sheet for 3...

In this ratios worksheet, learners find the missing number in the second ratio in the problem. Students complete 9 ratio/proportion problems.

In this equivalent proportion worksheet, students identify ratios written in three different forms (with a colon, with the word "to" and as a fraction). Students write the ratios as a proportion and then determine their equivalency. ...

In this missing proportion worksheet, learners solve for a missing variable to create a true statement. The two-step process of cross-multiplication and division may be used to solve given ratios. This one-page worksheet contains ten...

In this proportion instructional activity, students create a proportion from a set of four numbers. They write ratios that are equal to each other. This one-page instructional activity contains ten problems.

Tie the unit together and see concepts click in your young mathematicians' minds. Scholars apply the properties of similar triangles to find heights of objects. They concentrate on the proportions built with known measures and solve to...

In this trigonometric ratio worksheet, students determine the length of a side of a right triangle, or the measurement of angles using trigonometric ratios. This one-page worksheet contains 24 problems. Answers are provided at the bottom...

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...

Compare the ratio of genders in classes with a lesson that revisits ratio terminology. After finding the ratio of boys and girls, the class then finds the time it takes to pass out papers and determines the associated rates.

Students use polygons to explore division. They use pattern blocks to represent whole numbers and fractions. They discuss divisors, factors, dividend and products. In groups, students present models and solve problems. They justify their...

In this geometry worksheet, students describe the effect of a proportional change on the perimeter or circumference and area of the given circles or quadrilaterals.  The one page worksheet contains ten problems.  Answers are...

A nicely put together basic introduction to slope.  Slope is defined, and explained. The formula for calculating slope is shown and there are practice problems. There are questions about horizontal and vertical slope, as well as...

What does math have to do with a sore throat? When you mix water and salt you have a great review of how to represent proportional relationships by an equation or graph. Here the proportions of the mixtures may be different, but the...

And they're off! While two runners are at track practice, your mathematicians' job is to find out who leaves the other in the dust. The activity provides a variety of data that can be computed into unit rates for comparisons. Available...

A different-than-normal problem that allows learners to practice their reasoning to find an answer. The problem bases itself off a graph drawing of a store that needs to install security cameras. The challenge is to find which placement...

Take your class on a North American adventure with a currency conversion problem. Pupils are asked to change US dollars into Canadian dollars and then to Mexican pesos. The commentary includes two solutions, converting by unit rates and...

What starts as a basic question of division and remainders quickly turns abstract in this question of related ratios and radii. The class works to surround a central coin with coins of the same and different values, then develops a...
