Pupils explore how numbers can identify objects. In this math lesson, students determine how numbers are used to describe objects used in quantitative data collection.

Students reflect on the uses of mathematics in their daily lives and work in pairs to design brochures that make specific mathematical concepts clear and interesting to a popular audience.

Learners explore area and perimeter through coordinate geometry using student literature, hands-on manipulatives, and the Internet.

Students are introduced to a method for finding square roots used by the Babylonian people of Mesopotamia. The method involves dividing and averaging, over and over, to find a more accurate solution with each repeat of the process.

Students use an ancient math game to establish the context for solving problems by investigating them in a systematic and mathematical way. They also need to have the ability to solve various types of equations.

Students calculate the Fibonacci sequence of numbers. Through the use of Fibonacci numbers in flowers, leaves, fruits, vegetables, pine cones, and other forms of nature; students explore how Fibonacci numbers occur in nature. Then they...

Sixth graders read the book "Sir Cumference and Knights of the Round Table" to introduce them to the concept of Pi. As a class, they discover where Pi originated and define the terms circumference, radius and diameter. To end the...

Fifth graders examine how to see patterns by showing how things work together. They identify, analyze and determine a rule for predicting and extending numberical patterns involving operations of whole numbers, decimals and fractions.

Students compare and order numbers. In this geometry instructional activity, students write equations for inequalities. They differentiate and apply concepts of triangular properties to solve problems.

Students explore physics by participating in a science activity in class. In this flight properties lesson, students identify Bernoulli's principle of flight and his theory of statics and motion. Students conduct a demonstration by...

Fifth graders review the concept of negative numbers and how the are placed on a number line. After the review, 5th graders practice placing negative numbers on a number line in a whole class setting.

Fifth graders review the concept of prime factorization. Then, they use the rules for divisibility and other notions to find the prime factorization of unfamiliar numbers. They solve problems in a whole class setting.

Second graders categorize fish crackers into groups by color and compare the two groups using the symbols <, =, and >. They use concrete objects to solve number sentences with equalities and inequalities.

Fourth graders complete a worksheet that asks them to order operations within a mathematical expression. students evaluate the expressions in the correct order using mental math and paper. The results are recorded on the worksheet.

Students research biographies of Americans who advanced science. They create an obituary for the person to share what information they have gathered. They discuss the importance of the obituary as the "final word" of a person to complete...

Ninth graders study the correct way to solve equations using the order of operations. They apply a mnemonic device to remember the proper order.

Learners explore how to select unbiased random samples as they choose report data to include on maps. They propose methods for choosing random numbers and discuss their advantages and disadvantages. They consider bias in science.

Students measure the speed of moving marbles and use the results to calculate velocity and momentum. They analyze the events preceding a Japanese train crash.

Students calculate simple probabilities using mathematics then roll dice to test their predictions.

Students recognize patterns in a numerical sequence, create new patterns and predict outcomes to established sequences.

Second graders explore and develop algebraic formulas based on their own ages as the known variable. This is a clever, and simple, way to introduce the concept of algebra to young students.

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...

Students participate in an experiment involving the square root of two. They use different methods to solve the problem.

Students are responsible for creating a border around a triangular garden spot, of which they know the measurements for two sides. They use the Pythagorean Theorem to calculate the third side and complete the garden.
