Standards

CCSS.MATH.CONTENT.7.G.B.4

Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.

CCSS.MATH.CONTENT.7.G.B.5

Use facts about supplementary, complementary, vertical, and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.

Driving Question

How does changing the dimensions change the volume and surface area (SA) of 3D figures?

Entry Event

A trifold to explain the sizes of doghouses and various SA and Volumes, as well as a Clifford clip to show the importance of dimension for the size of the dog.

Public Product

Parents of students will be invited to a parent night and will hopefully buy the doghouses to help sustain the project for next year.

Students will have created a trifold brochure showing the 5 different doghouses and their different SA and Volumes as their Summative Assessment. These will be available for parents to look at and ask students questions.

Materials

• wood (4×8 plywood & 2x4x8 posts)
• paint
• nails
• hammers
• paint brushes

Formative Assessment 1

Real time with doghouse

Can you determine and show the dimensions of all 2D surfaces of the doghouse upon request?

Formative Assessment 2

Worksheet-showing their work on paper

Can you determine the area of all surfaces of the doghouse?

Formative Assessment 3

Google Form for Team with work turned in on paper

Can you find the surface area of the entire doghouse and determine how much paint (gallons) is needed to paint the house?

Formative Assessment 4

Real-time showing how to measure HT

Can you determine the height of a composite 3D figure (rectangular prism and triangular prism)?

Formative Assessment 5

Worksheet with work and answers

Can you determine the volume of a composite 3D figure (rectangular prism and triangular prism)?

Formative Assessment 6

Trifold Brochure

Create a trifold brochure showing your understanding by comparing and contrasting how the different dimensions of two doghouses affect the surface area and volume.

*Must have paragraphs by each team member explaining/supporting their knowledge/understanding.
