What happens when you have a recipe and need to up the measurements? Here is a lesson that explains how to use ratios to convert measurements and percents with worked out problems. Also provided are additional resources and practice...

Mindful middle-schoolers read and solve a number of word problems. Learners copy and discuss what they believe their strategies are in solving each problem. They also write their findings and share with the rest of the class.

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

Do these items have the same ratio? Through a learning contract, pupils master proportions by practicing proportions via word problems, graphs, and with manipulatives. An exit ticket checks for understanding at the end of the...

Examine food labels to determine percentage of fat and sugar to total calories with middle schoolers. Daily nutritional guidelines are discussed and learners will decide how well their foods fit into a healthy diet. In the provided...

Find the percent of the population that meets the criteria. The 17th segment of a 20-part unit presents problems that involve percents of a population. Pupils use tape diagrams to create equations to find the percents of subgroups...

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...

A quick problem to test your mathematicians' knowledge on percent increase. Two different solutions are provided, mental math and computing. Ask your learners to include a description of what they did to supplement their answer.

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...

Stoichiometry sounds complicated, but it really means the study of the amount of substances involved in a reaction. The sixth lesson in an 11-part series has scholars use stoichiometry to find the theoretical yield of a reaction. Then,...

The probability of learning from this lesson is high! Learners calculate probabilities as numbers and as decimals. They see how to use a complement to find a probability and even try a simple geometric probability problem.

Students solve problems using ratios and proportion. For this algebra lesson, students analyze skittles and their different colors as they apply the properties of ratios and proportions to solve their problems.

In this relating percents, decimals, and fractions worksheet, students, with a partner, problem solve and calculate the answers to twelve word problems and mathematical equations.

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...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Learners explore the concept of Venn Diagrams through word problems. For this Venn Diagram lesson, students solve word problems about groups of people using Venn Diagrams. Learners use survey results about MySpace and Facebook in a...

Students explore the concept of percents. In this percents lesson, students discuss the prefix cent and words that contain that prefix. Students make bead necklaces and determine the percentages of certain beads in relation to the necklace.

Sixth graders express numbers as percents greater than 100 and less than one. For this lesson on percents, 6th graders work in groups with real life scenarios to develop an understanding on percentages greater than 100 and less than one....

Sixth graders use ratios to solve unit problems. Pupils write ratios in three different ways. In groups, they perform a bean activity, find ratios, and write them in simplest form.

Studets practice problem solving and comparison of quantities, ratios and prproportions. They develop a plan for determining the height of a flagpole complete with drawings and calculations. In addition, they complete a written...

Students perform activities involving ratios, proportions and percents. Given a newspaper article, groups of students count the number of letters in a given area. They use calculators and data collected to construct a pie chart and bar...

Students use charts to show fractions.  In this fractions and percents activity, students review fractions, percents and ratios.  Students create tables and color the cells to make different fractions.  Students answer...

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

Students explore the means and extremes of a proportion, the how to make a scale drawing.
