Today, my grade 8 students used Flipgrid to record a video showing that they could model their solution to an algebraic equation using manipulatives called Alge-Tiles. These are tiles that represent variables and whole numbers, and can be used to show why it is necessary to perform the same operation on both sides of an equation in order to arrive at the correct solution.
The Flipgrid website & app allow teachers to post a prompt, and for students to record a video response to the prompt. Students do not need an account - the teacher can either send them a link, or post a QR code that will take them directly to the prompt. It is extremely user-friendly, and free (with limited features - so far, these have been enough for my purposes) I created two video prompts (2x + 4 = 10 & 3x - 1 = 5) for students in which I modeled the use of Alge-Tiles. I wanted to make sure that students could review the steps, listen to the mathematical language, and access the example more than once. I have found this to be a valuable way of ensuring that all students hear the message as many times as they need to.
Students worked with a partner to practice modeling equations, and then when they were ready they chose one each to model in video form. Using iPads made it easy for students to scan the QR code and begin recording right away. And now that they have submitted their videos, I can assess them outside of class time - which means I can be more available to the class as a whole. I'm always excited when technology makes my teaching more manageable, and this particular app has a lot of potential to do just that.
Examples of student videos. This week, we worked on two-step equations with addition. Next week, I will have students create videos involving subtraction :
