MathFROG stands for Math Fun, Resources, and Online Games. The games and resources available here were developed by a team at the University of Waterloo and are intended for students in grades four, five and six. The lessons are self-contained, combining online mathematics games or technological tools with appropriate paper-and-pencil follow-up exercises, which can also be downloaded free of charge. Each lesson lasts about 45 to 60 minutes and includes information on the related Ontario curriculum topics that are addressed. A section for parents and teachers provides some background information on the activities, including a Master Lesson List that lists all the lessons in a table format that includes the expectations for learning within each lesson, the math topics covered by the related strand and the name given to the lesson. Kids can jump right into the lessons by following the link labeled Kidz. The website is also available in French.
