3-5
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!
3-5, 6-8
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.
6-8
The National Bank of Illuminations has been robbed! Students apply their knowledge of ratios, unit rates, and proportions to sort through the clues and deduce which suspect is the true culprit.
6-8
In this activity, students work in groups as contestants on a fictitious game show,
Now and Then.
They use their knowledge of percent computations and percent change to
answer each game show question. As a culminating activity, the students
create their own game show and host it in front of the rest of the
class.
6-8, 9-12
In this lesson, students purchase the common items used in their mathematics classroom such as desks, chairs, calculators, manipulatives, etc. They are given a budget that they must work within plus coupons that they must use when making their purchases. The lesson lets students have fun while applying the concepts of discount and percent. Since students use a purchase register to track their purchases, it also serves as a review of integer operations.
6-8
We are bombarded in the media with ads offering 0% interest or teaser rates of 2.9%. These ads are devised to entice us to sign up for these limited time offers that the companies tell us would be crazy to miss. The goal of these ads is to get us to use credit to buy on impulse. If we take the time to analyze the offer, we might realize that if it sounds too good to be true, then it probably is. In this lesson, students will work through a credit card scenario with a teaser rate, minimum payments, fees, and rate increases for being late.
6-8
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.
6-8
In this lesson, students will use formulas they have explored for the volume of a cylinder and convert them into the same volume for rectangular prisms while trying to minimize the surface area. Various real world cylindrical objects will be measured and converted into a prism to hold the same volume. As an extension, students may design and create a rectangular prism container according to their dimensions to compare and contrast with the cylinder.
6-8
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.
6-8, 9-12
In this lesson, students compare different costs associated with two
cell phone plans. They write equations with 2 variables and graph to
find the solution of the system of equations. They then analyze the
meaning of the graph and discuss other factors involved in choosing a
cell phone plan.
