I found this very complex mathematical formula that allows one to figure out the day of the week any date falls on. Don’t let the formula intimidate you! I did this with some 3rd graders today and with a few explanations, they were able to figure it out. So can you!

What if you get a decimal that is higher than 7?

You basically ignore the digits after the decimal place. If your remainder is more than 7, that means that you can divide more. For example, 14 divided by 7. If you said 7 went into 14 one time, there would be a reminder of 7. That just means that 7 can go into 14 two times. Does that make sense?
