Vacation Homework

Assigning vacation homework is always a struggle for me.  I want the students to continue practicing the skill, but no one is there to guide them so how much help is the assignment really?  I also want to respect the fact that a vacation is a vacation and, while they should be practicing the skills they've been learning in school, they should also be spending time with family.  on top of all of that, i already have tons of grading to do and definitely do not need 50 15 page worksheet packets thrown into my lap next Monday.  This year for Thanksgiving I decided to try something different.  I found some great websites for Math practice and I decided to make a calendar for students to practice (in a fun way) each day of break.  
I also found that some students needed more practice with the basics so I leveled the assignments.  Students were free to do both calendars, but they were required to do either Level A or Level B based on their needs.  

It will be interesting to see if students actually complete this work, but many seemed very excited that they were being asked to play games instead of complete worksheets, so that's a good sign!
