Seventh graders determine if a number is prime or composite.  For this determining if a number is prime or composite lesson, 7th graders use a website to help find all prime numbers between 1 and 100.  Students use a website to...

Students discover the Sieve of Erathosthenes. They explore a method to find all the prime numbers in a group of numbers. Using models, students practice divisibility rules while examining the difference between prime and composite numbers.

Students create factor trees.  In this prime and composite instructional activity, students model fractions using tiles.  They create factor trees and identify prime and composite numbers.  Students use grid paper and...

Banks are responsible for keeping our financial information safe. Mathematics is what allows them to do just that! Pupils learn the math behind the cryptography that banks rely on. Using polynomial identities, learners reproduce the...

Groups plan their escape carefully. Three three-tiered puzzles help a story character escape their situation, each involving integer sequences, transformations, and geometric constructions. The teacher resource includes...

Use paint to teach about cryptography. Scholars explore public key cryptography by attempting to mix a secret color using paint. After the activity, they investigate the Diffie-Hellman method using prime numbers, exponents, and modular...

Ninth graders factor equations and find prime numbers. In this algebra lesson, 9th graders find the factors and prime factors of a number using multiples and relatively prime numbers.

Eleventh graders participate in a gallery walk activity to identify past Canadian Prime Minister.

Students are introduced to the concepts of latitude and longitude. In groups, they identify the Earth's magnetic field and the disadvantages of using compasses for navigation. They identify the major lines of latitude and longitude on a...

Fifth graders discover the connections between algebra and geometry. With a focus on arrays and factors, they are introduced to multiplication. They develop an array for multiples of 2 through 10 and identify the factors of each row....

Students explore the characteristics of sets and Venn Diagrams. Given data, students practice determining the placement of elements in a Venn Diagram. Students discuss the correspondence between data sets and their graphical...

Sixth graders experiment with dice, playing cards, pennies and computer-generated simulations to calculate probability. They use compiled data to make predictions.

Students will identify the parts of a cannon and practice demonstrating a mock firing. In this math and science lesson plan, students read background information on the cannon and its firing. Students read about and role play positions...
