We’re moving into the downhill slide of school, which means geometry and measurement in math. Â I like that these units fall toward the end of the year because they are more hands on, and typically more engaging. Â We started with area and perimeter a couple of weeks ago. Â While we did the standard practice activities, including marking out shapes in the hallway to calculate perimeter, I augmented with a couple of iLessons to keep the kids engaged.
At the start of the unit, I taught the kids how to use the app Jungle Geometry. Â This is a great app, with a wide variety of different geometry and measurement tasks. Â My students used the area and perimeter tasks in the app this time, but we’ll use this app again when we do more of the geometry standards. Â Jungle Geometry is a favorite of mine because I can customize the levels, measurement units and tools, and differentiate for each student within the app. Â There are a ton of customization tools, making this perfect for my multi-level group. Â You can read more about Jungle Geometry in my review here at FunEducationalApps.com.
By far my favorite activity was the students’ performance assessment. Â Students were given the task of creating a tutorial for how to find area and perimeter. Â I had already created my own tutorial that the students utilized for a note-making activity. Â Now it was their turn. Â Students were given a rubric of what needed to be in the tutorial: definitions of both area and perimeter, formulas, examples and directions for solving problems, and example problems with pictures. Â Students could work in pairs or alone – with the stipulation that I had to hear both voices if students worked together. Â The results were amazing!
My students are very familiar with the app Explain Everything, so we used that as our platform for creating the tutorials. Â Students utilized the shape and drawing tools, the text features, and even added some photos they took of the shapes we had measured in the hallway. Â Narrations went from 40 seconds to 9 minutes. Â And they all were great.
As a teacher, one of the best things about students creating tutorials, are the videos that aren’t right. Â I had a student who kept calculating perimeter wrong every time, and I couldn’t figure out what he was doing. Â Because he created the tutorial and had to explain his thinking as he did it, I was able to analyze his errors. Â He was adding every side twice, because in the examples of rectangles I had given the class, each short and long side was added twice. Â So when he found the perimeter of a pentagon, he added each side twice. Â I never would have figured this out if he hadn’t explained his thinking in the tutorial. Â It was an easy fix. Â I just needed to know where the problem was.
Having listened to the 9 min. explain everything explanation, I found that your student knows how to manipulate the app features (better than I) as well as explain his thoughts. It was a great lesson. Bonnie
