My Take
This is an excellent teaching tool to reinforce and reteach concepts. I like how easy it is to use and how much the students enjoy using it. It improves my teaching because students are working at their own paces so that work is individualized. It has a free version and a paid version. The free version is sufficient to use in the classroom. Each student has an individual log in, and students can access the assigned tasks at home. I would recommend this online resource for teachers.
How I Use It
I have used this as a supplemental resource and for reinforcement of concepts being taught in class. It is easy to search for the topics you want to use. There is a plethora of options for many subjects. There are videos, worksheets, interactive activities, and other options. It is very colorful, engaging, and interactive for students.
