## Reflection: Lesson Planning What is a Digit - Section 4: Closing

As expected, most of the children defined a digit as a number. Two children were still unclear about what a digit was, and will need more reinforcement of the term. For all of the children I will continue to use the term digit to refer to a single number and remind students that the digit can only be one number and not more than one.

This is a concept that is often assumed that children understand. When we probe deeper we realize that the math term we are using is not one that children understand, or understand in the way that we are using it.

It is important to check for understanding when using math terms.
