Middle schoolers play a game based on "The Amazing Race" to practice using rates and fractions. In this fractions and rates lesson, students work in small groups competing to complete the tasks in the quickest time. At each stage of the...

Objects may be more linear than they appear. Scholars investigate the relationship between the number of bone mineral density scanners in the US and time. Once they take the natural logarithm of the number of scanners, a linear...

Explore measuring various objects using square centimeters. Learners create various shapes using five centimeter cubes, calculate the area in square centimeters of different classroom objects, and discover who has the largest mouth,...

Creative problem solving is fun and helps kids conceptualize content. They use grid paper, manilla paper, and markers to cut, draw, and show given double-digit numbers as many ways as they can.

Looking for a good lesson on measurement? This one could be for ytou! Learners select and use appropriate nonstandard units to measure and compare lengths and weights of real-life objects. They use problem-solving skills to design a...

Elementary or middle schoolers use ratios to discover some nearly constant relationships between measurements of parts of the human body. They find and record pairs of measurements and determine the relationship between the pairs. Pupils...

Using rates from a rental car company, young mathematicians graph data, explore linear relationships, and discuss the role of slope and the y-intercept. This lesson allows for the discussion of independent and dependent variables, as...

Highlight the process of mathematical discovery for your classes. This lesson examines the development of the Fundamental Theorem of Calculus over time. Understanding the history of the theorem helps create a better understanding of the...

Youngsters examine how to tell time to the nearest half-hour. They discuss why people wear watches, listen to the book "What Time Is It?" by Sheila Keenan, view examples on a model clock, and complete a worksheet with the teacher.

Children use the length, width, and height of an object to calculate the volume of a rectangular prism. They observe how to multiply three numbers at a time, and define volume. Pupils observe as the teacher demonstrates how to determine...

Students investigate fractions while adding and subtracting mixed numbers. They discuss how to add and subtract mixed numbers and they practice working with mixed numbers. They complete a worksheet while working with mixed numbers.

Kindergarteners explore various representations and uses of numbers to develop number sense. They participate in an activity and arrange patterns into groups. Students compare the sets and describe the objects in each set.

Second graders review measurements in inches and practice measuring different objects. As a class, they estimate various objects in their classroom and compare their estimation to the actual measurement. To end the lesson, they complete...

Second graders measure and record the length of five different objects around the room. They watch as the teacher measures items using a ruler. A ruler is a foot long. Everyone listens and watches as the teacher continues to teach that a...

In this function learning exercise, students complete five lessons all with exercise sets, examples, and definitions, and one set of miscellaneous exercises.  The concepts covers include: composite functions, inverse functions,...

Young learners start out by going to the board to draw lines through shapes to identify halves. Then they are given a square of paper and are directed to fold the paper into halves and then into fourths. They color the halves...

Students compare, sort, and describe shapes. Using a button collection, students identify the shape, color number of holes, etc. Students play a description game with the buttons. They create a chart and name items that are the same...

Students assess their own energy use to help develop an awareness of the different types of natural resources affected by consumers. Their calculations show them how much they are personally impacting the Earth. Very meaningful and...

First graders use geometric shapes to create and extend patterns. Students read a book and view African garments. They identify patterns in the garments. Students create and decorate a paper vest with geometric patterns.

Students identify attributes in real-life objects and models of solids and connect these attributes to characteristics of shapes such as circles, triangles, squares, and other rectangles. They discuss the ability of the object to roll,...

First graders listen as the teacher reads a story involving cross-continent traveling. Students collect a random sample by tossing an inflatable globe and recording whether they touch land or water each time they catch the globe in order...

Fifth graders use formal geometric language to describe polygons (and other shapes) that will tessellate the plane and those that will not. Students make generalizations about the characteristics of a polygon (or other shape) that will...

Third graders roll a die seven times, each time determining whether to add that number of tens or that number of ones to try to make a sum as close to 100 as possible without going over.

Fifth graders use interlocking cubes to build towers to represent factors of numbers and place the towers in the appropriate places on a Tower chart in order to look for patterns. They work in partner groups, and finish by writing...
