Students will plot points on a coordinate grid to represent ships
before playing a graphing equations game with a partner. Points along
the
y-axis represent cannons and slopes are chosen randomly to
determine the line and equation of attacks. Students will use their
math skills and strategy to sink their opponent's ships and win the
game. After the game, an algebraic approach to the game is
investigated.

In this lesson, students explore linear equations with manipulatives
and discover various steps used in solving equation problems. Students
use blocks and counters as tactile representations to help them solve
for unknown values of
x.

Students use equations to determine eBay profit on new technology. EBay is an online auction agency. For a limited time after a “new” product’s street release date, it is possible to track the profit that sellers make for auctioning them on eBay. Students use previous data of selling prices to derive a linear equation for the “closing bid price” on a product.

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.

In this lesson, students determine the time it takes for a roller coaster to reach the bottom of its tallest drop. They use tables and graphs to analyze the falls of different roller coasters. Students conclude the study by creating their own roller coaster and providing an analysis of its fall.

Students studying linear equations inevitably explore the concept of slope. Slope is a recurring topic found in algebra when studying linear equations, in trigonometry when studying the tangent ratio, and in calculus when studying the derivative. Lead students to a deeper understanding of slope and linear equations using elevation and distance data from a popular mapping website.

Use tiles to represent variables and constants, learn how to represent
and solve algebra problem. Solve equations, substitute in variable
expressions, and expand and factor.
