Math dude is great for students in the upper primary grades to practice prime, composite and special numbers as well as to find the fraction of the day, the percent of the day, the decimal of the day, work on balanced equations, use prime factorization, etc.
Math dude is designed to be done every day. Students use the day of school to work on different math concepts. For example, on the first day of school, the number is 1. It is a special number because it has only one factor. The fraction for the day is 1/100, the decimal is .01, and the percent is 1%. If the date were 8-14-14, students need to use those numbers and various operations to create a balanced equation.
I plan to use this file on the tablets for the students to solve each day. I will upload it to the LMS that we have for each student, they will open it in Notability, complete the assignment, and submit it back to the LMS. This is also done effectively as a whole class activity.
