My kids LOVE boiled eggs, so I make a large batch for easy snacks. Using the crayon in the package, I write different sight words on the eggs. Before they can eat an egg, they have to read the word.
***The eggs need to be cool before writing on them. Otherwise the wax melts a bit and can make reading the words difficult.*** (see picture below)
a math equation (addition, subtraction, multiplication, etc)
This is a great way to reinforce what your child is already learning.
A cheesier way to look at it is: A great way to feed their minds and their tummies. ;)
