## Scale drawing with geometric figures

This project is for Module 1 of the Engage New York Math program for 7th graders. It addresses the subjects discussed in lessons 16 through 20. I attempted to incorporate all of the ideas presented at the end of this module into a project. This project should take about 5 days if you have regular 40-45 minute cycles.
The kids split into classes at the end of the presentation/notes. Students were expected to work with a partner or in a group of three, but they could also work alone. I was intrigued to see who they choose to work with and how they chose to work (solo, doubles or groups of 3).
It was time for the kids to have a work period after a full day of notes on the first day. The second day was devoted entirely to work. It didn’t turn out the way I had hoped. I wanted to set the tone and have them collaborate on the project with their newly formed affiliate groups. I told them they had 15 minutes to work and that we’d check in after that. Some groups breezed through it, while others struggled mightily. After some time to work, we reconvened after 15 minutes, and my co-teacher and I alternated directing the students through the problems, attempting to ensure that the majority of them understood the content. The kids were given a few minutes to begin their home practice.

## 7th grade scale drawing project intro

Consider the equation y = kx, which we use to express proportional relationships. Why is it necessary for the line’s graph to pass through the origin? When responding, think about the coordinate pair at the origin and how it applies to the equation.
We started talking about this in Unit 11’s lesson 11. And if we plug in a value of zero for x, the y value is also zero, the graph of the lines should go through the origin. When you multiply the constant of proportionality (k) by zero in the equation y = kx, the y value will always be zero.
During the independent portion of the Do Now, I walk around the room searching for students who underline everything. These students may need further assistance in locating only the details they need. I’m still on the lookout for students who don’t annotate. With advance notice, these students will complete this task during lunch. “Underline or highlight the important fact that will help us answer the key question,” I say if students need immediate guidance on what to annotate.

### Floor plans and scale ratio – 7th grade math

Are you looking for ways to teach scale drawings? You’ve come to the right spot. Scale drawings can be a lot of fun for students, and they’re a perfect way to get them to think about math. You’ll find 8 fun scale drawing activities to try in your classroom in this article. Check out this article about using I Can Statements to break down teaching scale drawings for more scale drawing ideas and tips. Check out this post for a guide to incorporating scale drawings through discovery and interactive notes. Independent practice opportunities, technology-based resources, analysis games, and enrichment activities are among the eight scale drawing activities listed below. Let’s get started!
Any definition can be practiced in a variety of ways. The art of teaching is to find a successful balance of modeling, practicing, and reinforcing learning. I’ve included some activities that I use while teaching this idea in the section below. They can be used for a variety of purposes in the lesson, including anticipatory collection, modeling, rehearsal, and closure. You can mix and match them to make something that will work for your students. Depending on the activity, these methods can be used as math centers, partner work, independent work, or with the entire class.

Helpful videos, solutions, and lessons Students in Grade 7 learn how to solve problems involving geometric figure scale drawings, such as computing real lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
1. Vincent recommends to the Student Government that a basketball hoop be built at his school, along with a court marked with all of the shooting lines and boundary lines, for students to use during recess. He suggests the construction of a half-court style, as shown below. After speaking with school administrators, he learns that it would be accepted if it suits on the school’s empty lot, which measures 25 feet by 75 feet. Will the property be large enough for the court he envisions? Justify your role.
2. The illustration depicts a greenhouse. Every 20 meters, one centimeter is applied to the scale. The drawing’s squares are 1 cm by 1 cm in size. Based on the specified drawing, determine the actual length and width.
3. A graphic designer is working on a tablet commercial. She must enlarge the image shown here so that 0.25 inches on the scale image equals 1 inch on the actual advertising. What are the dimensions of the tablet in the advertisement?
