Last week my students started to plot points on coordinate grids. They were identifying different quadrants and becoming more confident with drawing shapes on the plane. While reflecting on last week’s activities I noticed a Tweet that was sent our replying to one of my blog posts.

I’m a rookie when it comes to Desmos. Most of the stories I hear involve middle or high school students. I needed to find something that worked with my elementary kids. So I started to research and did a little bit of exploring to see how this could be used with my third grade class. I ended up looking up some of the templates but had a bit of trouble finding an extremely basic rookie-like coordinate plane activity for my students. I decided to go the route of creating a template and having students manipulate created points for a project. Click here for the template.
I quickly found that students had no idea how to use Desmos. I gave the students 5-10 minutes to orient themselves. Students were asked to move the points to certain coordinates on the grid. As they moved the points students started noticing that the tables on the left side of the screen changed. Students started connecting how the tables changed and this helped reinforce concepts learned last week. After this introduction time, students were given a rubric that contained the following:
- Move the points on the grid to create two angles
- The angles need be located in two different quadrants
- The angles need to be acute and obtuse with arcs located in each one
- Indicate the measurement of each angle
Students were then given 15-20 minutes to create their projects.
Students created their angles by moving the points around the grid. Students then shared their projects with the class.
Students took a screenshot and then added the degree measurements to the angles. The class reviewed the projects and students explained how they plotted the points. This project seemed to help students make the connection between points and the x and y-coordinates. It also reinforced skills related to angle classification and measurements. I’m looking forward to expanding on this project next week.
