Start by writing the alphabet on the board. Then under each letter add a value - the easiest way to do this is to put 1 under a, 2 under b, 3 under c and so on!
When each letter has a value ask students the following questions.
What is the value of your name?
What is the value of a classmate's name?
Whose name in the class has the highest value?
Whose name has the lowest value?
And you can get even more challenging by asking them questions such as these.
Whose name has a value of between 20 and 25?
Whose name has a value of 30 or whose name value is closest to 30?
This is a really simple activity to prepare yourself or this sheet with the Name Values activity is available in my Back to School Math About Me collection.

Hope this helps with your Back to School Math!
