N/APros: The concepts covered and the supporting materials provided are great and highly useful to any teacher or parent.
Cons: Though the video instructor tries hard, he may come across as a bit too goofy to students, and the "talking head and graphics" format might get boring.
Bottom Line: Math videos and resources explain concepts very well, but be prepared for a few student groans along the way.
All of the videos on Math Antics are available for free and are great for introducing or reinforcing math concepts for students. They can be used as a wholeclass introduction to a lesson or with individual students who may be struggling with certain skills. The other resources (exercise handouts, explanation videos, worksheets, and answer keys) make it easy for teachers to incorporate the videos into their lessons. These resources are available for free for some lessons, but most are accessible only with a $20peryear subscription.
Continue reading Show lessMath Antics is a site that provides videos and supplementary materials covering five math topics: arithmetic, fractions, geometry, percents, and algebra basics. Through the free videos, the instructor (Rob) illustrates each concept with detailed, stepbystep explanations and graphics describing how things work. Many of the videos build upon previous concepts and encourage students to "go back a step" to a previous video if needed.
Some of the extra materials are free, but most require a $20peryear subscription. Printables include onepage exercises that briefly cover a topic and worksheets that provide more focused practice. In addition, example videos explain problems step by step, and answer keys to the printed materials are provided. The materials aren't formally linked to any set curriculum or the Common Core State Standards; they're instead meant to supplement what a student is learning in class and not replace it.
In terms of presenting information clearly and building upon concepts, Math Antics' videos and resources do a fantastic job. They're also helpful for teachers or parents wishing to build their own skills. For a student being first introduced to the ideas or needing extra help, the materials are laid out well and take students step by step through the problems.
The drawback to these videos is that they feature a "talking head" and floating graphics, which can get boring for students upon multiple viewings. Each video also comes in at an average of 10 minutes, which may be too long for younger students. The videos have a bit of a cheesy flavor that may go over really well with some students and may induce groans in others.
Overall Rating
Engagement Is the product stimulating, entertaining, and engrossing? Will kids want to return?
While the concepts presented are highly useful, video production is simple and a bit cheesy. With an average video length of 10 minutes, younger students may quickly find themselves bored.
Pedagogy Is learning content seamlessly bakedin, and do kids build conceptual understanding? Is the product adaptable and empowering? Will skills transfer?
The video host tries hard to engage students and presents lots of highly useful math concepts in an easytounderstand way. The supporting materials available with the subscription, while traditional, are great reinforcers.
Support Does the product take into account learners of varying abilities, skill levels, and learning styles? Does it address both struggling and advanced students?
Each lesson flows nicely from the previous one, covering many of the basic math concepts students need. The site itself is easy to navigate, and the extra materials pair nicely with the videos.

 5.NF.7.c
Solve real world problems involving division of unit fractions by nonzero whole numbers and division of whole numbers by unit fractions, e.g., by using visual fraction models and equations to represent the problem.
