1 Hook

On Nearpod students are introduced to the following problem:

Students work in pairs and must decide how large the chicken coop must be based on the following parameters:

Each pair is allowed 10 chickens. There are two types of chickens that pairs can choose from. Students can choose any combination of chicken types to include in their coop.

  • Large Fowl requires 4 sq. ft. of floor space
  • Bantam Chickens requires 2 sq. ft. of floor space

Question Prompt: How large must the chicken coop's floor space be to accomodate your group's 10 chickens?

Students show work using "DrawIt" feature of Nearpod App.

2 Guided Practice

Activity: Creating — Internet for Research

Part 1:

At this point students will have the size of their rectangular base. Students are told their chicken coop must have a height of 6 ft. Students will construct a model of their coop using Formit App. Then they will be instructed to calculate the surface area of the coop.

Part 2:

After finding the surface area of the coop, students will have to determine the cost of purchasing materials to cover the frame of the coop. Students are free to choose from the following covering types or combinations of. They research costs online. The only constraint is a budget of $100. The chicken coop frame is provided for.

3 Wrap-Up

Free, Paid

Students will present their final design/proposal showcasing their math work, as well as how they met the constraints and budget. 

Class will vote on the best chicken coop design with best value for money.
