In this activity, students will multiply and divide a recipe to feed groups of various sizes. Students will use unit rates or proportions and think critically about real world applications of a baking problem.

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 will use dimensions of round and square hay bales to calculate and compare volumes. They also calculate unit prices to determine which hay bale is the better value. Finally, students explore how to fit round and square bales into a barn to maximize volume, and decide which type of hale bale is the best choice.

In this lesson, a string will be stretched across the classroom and various points will be marked for 0, 1, 2, 3, and 4. This classroom number line will be used to show that all proper fractions are grouped between 0 and 1, and that improper fractions or mixed numbers are all grouped above 1. Students clip index cards with various proper fractions, improper fractions, and mixed numbers on the clothesline to visually see groupings. Students then play an estimation game with groups using the same principle. Encouraging students to look at fractions in various ways will help foster their conceptual fraction sense.

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.

Darts is a popular game in which players throw 3 darts, one at a time, aiming for a target. Different regions of the board give different points. In this lesson, students learn how to change the scale of an object, and how to measure and draw angles using a protractor. By the end of the lesson, students have created their own dartboard. The dartboard can later serve to emphasize properties of angles and angle pairs. This activity is a good one to do prior to a lesson in which students construct circle graphs. The practice they will get in this lesson drawing circles and measuring angles will help them in their quest to more accurately create circle graphs.

Tile floors are common in many homes and businesses. They are durable, beautiful, and can add value to the home or business but they can also be costly. In this lesson, students will create and estimate the cost of a tile floor design using geometric shapes, ratios, proportions, and percents. All cost estimates are based on the purchase of full boxes of tiles so students have to weigh cost against design considerations. Cost estimates also include labor and taxes for a more realistic estimate of what it costs for a great looking floor.

Students will conduct five experiments through stations to compare theoretical and experimental probability. The class data will be combined to compare with previously established theoretical probability.
6-8
Student will conduct a coin tossing experiment for 30 trials. Their results will be graphed and shows a line graph that progresses toward the theoretical probability. The graph will also allow for a representation of heads or tails throughout the experiment.

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.
