Khan Academy is a useful and versatile tool that can help teachers, students, and parents to reinforce classroom concepts and lessons virtually anywhere. The free website has thousands of videos, quizzes, and helpful hints to help students better understand a selected topic. The age range and subject matter covers almost everything that a student could ask for. While browsing on the site I chose three lessons that I found to be interesting and meaningful.
The first lesson I chose was a math lesson aimed towards first graders to help them understand the relating addition and subtraction. This lesson included an easy to follow video clip that could be quite helpful for students to visualize the concept. The video was easy to follow and explained the lesson step by step, after the completion of the video the was a small series of problems quizzed the students. The seven questions were helpful and if the student needed a hint or an additional video to help out it was easily available. If the student gets the answers correct there is a happy song played along with some cute graphics that can be really exciting and encouraging for younger children.
The next lesson I chose was geared toward kindergarten students about basic shapes. This lesson was comprised of two colorful videos and two sets of practice questions to reinforce the lesson and test students of their retention. Again this lesson was age appropriate and appeared to be well laid out. I like that they keep the videos short and to the point as children at this age are easily distracted.
The third lesson that I selected to review was an introduction to nouns; this lesson included two detailed easy to follow video clips and two sets of practice questions. It gives students a clear explanation of what a noun is while briefly explaining both singular and plural nouns. I thought that the lesson was a well thought out introduction that can be followed up with more detailed lessons.
