Learners study how to calculate elapsed time. In this elapsed time lesson, they determine how to calculate the ending time of an event when they are given the starting time and the elapsed time. They participate in direct instruction,...

Learners predict the-outcome of an event. In this algebra lesson, students compare and contrast the probability of an event occurring. They calculate the odds of a simple event and make estimation.

Students calculate the probability of an event occurring. In this probability lesson, students differentiate between independent, dependent or compound events. They find the range of the data.

Students solve problems with percents, decimals and fractions. For this algebra lesson, students convert between fractions, percents and decimals. They estimate their answers and calculate their answer.

Students solve quadratic equations using graphs. In this algebra instructional activity, students factor quadratic equations and graph their answer. They discuss the shape of their graph based on the function.

Pupils build a stack of pennies as tall as possible, recording the number of pennies they are able to stack before the tower falls. Then, sharing answers, they determine the average number of pennies that could be stacked.

Learners investigate modular clock arithmetic and cryptography. They perform basic operations in modular (clock) arithmetic and encode and decode messages using simple shift and affine ciphers.

Tenth graders have been introduced to the concepts of translation, reflection, and rotation, and have practiced translating, reflecting, and rotating two-dimensional objects on the coordinate plane.

Students are introduced to the basic ideas needed for understanding linear functions.

Students gain practice reading coordinates and plotting points by participating in the Coordinates! Game. They demonstrate and test their skills with graph paper and the Maze Game.

Students discuss the nature of fractions and compare fractions based on a similar whole to determine relative size.

Fourth graders design a table and chair arrangement. In this mathematical reasoning activity, 4th graders place tables shaped like equilateral triangles so that they seat the appropriate number of guests. 

Students investigate the associative property of addition. In this associative property of addition lesson plan, students work in pairs and build addition problems with six blocks. They sit on either side of a desk so that they can...

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

Seventh graders investigate geometric shapes using tessellations. In this geometry instructional activity, 7th graders practice tessellations using different shapes. They create different designs using tessellations.

Young scholars explore animals that are endangered. They choose an endangered animal that they would like to keep from becoming extinct. Students create a persuasive presentation to persuade someone to understand why they feel keeping...
