Students study how to find prime numbers. They investigate the teachings of the mathematician Eratosthenes and apply his theory of prime numbers less than 100.

Students analyze and discuss prime numbers and the Sieve of Eratosthenes, a procedure to sort out prime numbers. They identify the prime numbers from 1-100 by eliminating all the multiples of the first four prime numbers, and circle what...

Third graders listen to information about Eratosthenes and review the definitions: prime, composite, multiples and divisible. They recreate Eratosthenes' method of compiling prime numbers. They create a poster.

Sixth graders listen to Demi's, On Grain of Rice: A Mathematical Folktale. They use the problem solving strategy of finding a pattern to determine the number of rice Rani will receive after 30 days. They create a spreadsheet which...

First graders explore patterns. They look for patterns in number problems and use algebra as a means of solving general problems. Students devise a strategy to solve the number problem.

Third graders create their own chenille stems to use during this and future lessons. As a class, they discuss the difference between equal and non-equal groups. In groups, they brainstorm a list of items that come in groups of two,...

Students engage in a study of the Pythagorean Theorem to classify the hypotenuse of a triangle. The teacher uses examples from the activity to aid students in comprehension of solving problems that involve problem solving. They create a...

Students examine apple production in the United States. In this interdisciplinary instructional activity, students use problem solving strategies introduced to solve math problems associated with apple production in the United States....

Students practice finding the perimeter of a quadrilateral. In this finding the perimeter lesson, students review the properties of squares and rectangles. Students explore strategies to facilitate problem solving and discover how to...

Young learners listen to a read aloud of Gail Gibbons book, Apples and the story A Red House With No Windows and No Doors. They compare characteristics of a number of kinds of apples, graph them and create a apple print picture. Learners...

Third graders tally, sort, and organize pizza orders from monthly school sales. They create an advertising campaign to promote the School Pizza Sale, record the data in graph form, compare and contrast the tallies throughout the year,...

If you want more pumpkin seeds, you should get a bigger pumpkin—right? Young harvesters use estimation skills to make a hypothesis about how many seeds they will find in a pumpkin before examining the real number inside.

The lesson starts out with a brain drain, which is a great way to get students to activate prior knowledge and build lasting connections. They tell everything they know about prime factorization, use their knowledge to...

A highly relevant and great cross-curricular project! In teams, your class will plot a course from the East Coast to Sacramento, California passing through all of the state capital cities along the way. As part of the journey, teams...

Teach young mathematicians the concepts of greater than, less than, and equal to with kinesthetic, visual, verbal, and numeric approaches. In a playful session that addresses multiple intelligences, your class will: dramatize a greedy...

How has the African American population changed over the years? Learners use charts, statistical data, and maps to see how populations in African American communities have changed since the 1860s. Activity modifications are included to...

Learners demonstrate that they can use a variety of coin combinations to make a single amount. They study all the ways to make 50 cents using coins using different coins.

Turn your 6th graders into detectives while growing their love of reading. Using critical thinking skills, they will be able to describe the five basic elements of detective fiction, read detective novels, make predictions, use the...

Students simulate going to a pizza restaurant, ordering a pizza, and determining whether a small, medium, large, or family size pizza is a "better-buy." Students calculate the price/per/topping and determine whether this price is "fair"

An engaging hands-on activity is presented. Learners of all ages are addressed in thie unique plan. K-5 learners identify, name, and define a rectangle, square, triangle, and the concept of area. Older learners prove the Pythagorean...

Students collect pennies and sort them in ascending order of dates. For the year on each penny, students research key events in history and pick a single event, explaining its historical significance. Then students use these events to...

Manipulatives make learning division easier! Your class will discover the difference between dividing with one- and two-digit divisors, and practice the procedures for each using the standard algorithm. They will use estimation to ensure...

Youngsters sort M & M's by color. They graph the M&M's by color on a graph. This classic lesson is a wonderful way to introduce the concept and technique of graphing to young mathematicians. Pairs of kids can make up their own...

Young mathematicians identify shapes and their correct names. They work with partners using various manipulatives and computer software to reinforce the concept. I really like these lesson plans. They are well-designed, the procedures...
