The Factor Game engages students in a friendly contest in which winning strategies involve distinguishing between numbers with many factors and numbers with few factors. Students are then guided through an analysis of game strategies and introduced to the definitions of prime and composite numbers.

When students play the Factor Trail game, they have to identify the
factors of a number to earn points. Built into this game is cooperative
learning — students check one another's work before points are awarded.
The score sheet used for this game provides a built-in assessment tool
that teachers can use to check their students' understanding.

The rules of Krypto are amazingly simple — combine five numbers using
the standard arithmetic operations to create a target number. Finding a
solution to one of the more than 3 million possible combinations can be
quite a challenge, but students love it. And you’ll love that the game
helps to develop number sense, computational skill, and an
understanding of the order of operations.

Students decompose 2-digit numbers, model area representations using the distributive property and partial product arrays, and align paper-and-pencil calculations with the arrays. The lessons provide conceptual understanding of what occurs in a 2-digit multiplication problem. Partial product models serve as transitions to understanding the standard multiplication algorithm.

In this lesson, students use a Venn diagram to sort prime factors of two or more positive integers. Students calculate the greatest common factor by multiplying common prime factors and develop a definition based on their exploration.

In this series of 3 hands-on activities, students develop and reinforce their understanding of hundredths as fractions, decimals, and percentages. Students explore using candy pieces as they physically make and connect a set/linear model to area models.

Oil spills are in the news. To make real-world connections, this lesson provides hands-on experiences with mixing oil and water, provides surface area information about the 2010 oil spill in the Gulf of Mexico, and gives students opportunities to estimate small oil spills of their own making.

In the first lesson (of two), students start a business from the ground up! Students collaborate to develop a product and are given a $1000 budget in which to start their business. Students participate in a live auction of real estate locations within the classroom, determine the wholesale prices of various products, and work together to develop an advertising campaign all to prepare for the big day- selling day!

This second lesson places students in the shoes of a real business owner. Students have chosen the products they want to sell, rented locations, and prepared advertising; now they get to experience the thrill of the sell as they spend their $200 on stores' merchandise(s). Students experience real-world applications of adding and subtracting decimals while learning what it means to be a smart consumer.

Project this lesson on a whiteboard and watch your students “number line dance” their way to fluency in estimation of products. The lesson is scaffolded to start students finding basic multiplication facts on a number line and ends with students estimating four digit products on a number line. Use the lesson to teach estimation of products or as a culmination of your own estimation of products lesson.
