#### Task: Miniature Golf

"Fore!" All right, no one really yells this out in miniature golf, but this well-defined activity will have your charges using lots of numbers in their unique design of a miniature golf hole. Included in the activity criteria is the...

Lesson Planet: Curated OER

#### Task: Grain Storage

Farming is full of mathematics, and it provides numerous real-world examples for young mathematicians to study. Here, we look at a cylinder-shaped storage silo that has one flat side. Given certain dimensions, learners need to determine...

Lesson Planet: Curated OER

#### STEM: Lou-Vee Air Car

A comprehensive lesson on acceleration awaits your physicists and engineers! Two YouTube videos pique their interest, then sample F=ma problems are worked and graphed. The highlight of the lesson is the building of a Lou-Vee air car!...

#### Finance: Depreciation (Double Declining)

Of particular interest to a group of business and finance pupils, this lesson plan explores depreciation of automobile values by comparing the double declining balance to the straight line method. Mostly this is done through a slide...

Lesson Planet: Curated OER

#### Information Technology: Photoshop Scale

Scaling is a practical skill as well as a topic to be addressed throughout the Common Core math standards. You are given three different presentations and a detailed teacher's guide to use while teaching proportion, as well as practice...

Lesson Planet: Curated OER

#### How Do I Design a Raised Bed Garden to Accommodate My Plants?

Give plants the best place to grow. Given constraints on plant spacing, pupils design a raised bed garden using graph paper, then calculate the perimeter, surface area, and volume. They use the provided costs of lumber and soil to...

Lesson Planet: Curated OER

#### “Putt-Putt” For The Geometry of It!

Take a swing at the task. Using their knowledge of polygons and solids, scholars design one hole of a miniature golf course. They calculate areas and perimeters, determine the cost of building the holes, make scale drawings, and create...

Lesson Planet: Curated OER

#### A Place at the Table

Find a seat at the table. Learners design a non-rectangular picnic table given constraints on the number of people that should be able to sit at the table. They draw blueprints and build scale models of their tables. After researching...

Lesson Planet: Curated OER

#### Building Sandcastles

Finalize the plans before playing in the sand. Learners design sandcastles using geometric and composite figures. They create blueprints, including the scale, and three-dimensional models of their castles. Finally, scholars calculate the...

Lesson Planet: Curated OER

#### What’s Your Party Like? An Exploration of Area

Who knew that a party is all about the area. Individuals draw out a patio on grid paper while planning to host a party. Using colored paper to represent the total area of the patio, learners cut out furnishings to add to the patio,...
