Young mathematicians identify central angles, arcs and radius of circles in this pre-calculus lesson. They identify the proportion of the circle based on its radius while they convert between degrees and radians measurements.

High schoolers explore quadrilaterals in this geometry lesson. They will draw a quadrilateral, measure the angles, and find the sum of the measures of the interior angles using Cabri Jr. The interactive capabilities of Cabri Jr. allow...

In this measurement worksheet, students make a measurement man to aid their understanding of the relationships between gallons, quarts, pints, and cups. They make the body of the man using one sheet of paper that represents one gallon...

We all have standards and scientists are no exception. Presentation covers standard temperature, standard pressure, temperature conversions, and absolute zero. It explains pressure using pascals, mm of mercury, atmosphere, and torr, then...

Groups of students rotate through five classroom stations to estimate, measure, and record volume, length, weight, mass, and area using both customary and metric measure. They evaluate their data to determine how close their estimates...

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

Young historians examine the cost of goods and services through the Consumer Price Index (CPI), output measured by Gross Domestic Product (GDP), and unemployment measured by the unemployment rate to gain an understanding of the economic...

Hold your horses! Young learners discover the history behind measuring the height of horses "by hands." They also study the history of Oklahoma, and how horses played such an important role in settling the state. An excellent worksheet...

In this missing angle measures worksheet, students subtract the angle that is given from 180' to find the missing angle measure. Students complete 6 problems.

Teach your class how to apply their knowledge of geometry as they explore the unknown. In order to find an unknown angle, students must understand that rectangles have four interior right angles, that right angles have 90 degrees, and...

Mixed numbers can be added conceptually, algorithmically, and physically. Have the class visualize mixed numbers by adding fraction bars together. They then discover the algorithmic process that simplifies adding mixed numbers. Finally,...

Is that a right triangle or a wrong triangle? Young mathematicians look at eleven different shapes and use a measuring tool of their choice to determine which triangles have right angles. Consider cutting out sets of the shapes to...

Don't just tell class members about how to measure inflation, have them experience it firsthand by asking them to work with real data and construct graphs!

Double the fun — calculate two measures of deviation. The lesson plan provides information to lead the class through the process of calculating the mean absolute deviation and the standard deviation of a data set. After learning how to...

Students measure angles using a plane table kit. In this geometry lesson, students use trigonometric identities to find the values of the length of a football field.

Measurement devices can be used to determine the height, length, or weight of all kinds of things, even plants and animals. This presentation acts as the basis for two estimation activities. Each activity requires the children to...

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

Practice money and measurement math with a thorough activity. Two examples at the top of the page remind fourth graders how to solve subtraction problems using decimals. After working through 14 problems, they then solve two word...

“The tempter or the tempted, who sins most?” Prediction, verification, judgment, and extensions of thought are all part of a Directed ReadingThinking Activity (DRTA) developed for Measure for Measure. The rationale, assessments...

Explore the measures of central tendency through a challenging task. Given values for the mean, median, mode, and range, collaborative groups create a set of data that would produce those values. They then critique other answers and...

Practice finding the area of squares and rectangles. Complete with a grid for third graders to measure each side, this resource will be helpful. Though the shapes vary in size, they all have four sides to make measurement easy. Pupils...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

Explore the meaning of scale and proportion with a set of five activities that examines the topic from elementary through high school. The first lessons explore ratio by examining pictures of different sizes. The next three activities...

Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared...
