In class, we have been working on square and cube roots and more recently, classifying numbers as either rational or irrational. Here are two skill checks you can do to check your understanding. Each skill check has four questions to answer. If you want, you can scan the QR code (that funny looking barcode on the top) to watch a video first. Then, complete the four questions. Scan the QR code on the top right to check your answers. You can download a QR code scanner app for free on your smartphone. Happy scanning!
Square roots can be used to find the length of one side of a square when given the area. How are square roots and the areas of squares related? Check out this video! Remember, if it asks you to log in, click in the top right corner to indicate you are student and avoid the log in!
