## Reflection: Developing a Conceptual Understanding Tally Graph - Section 2: Whole Group Interaction

It has always been difficult for my first graders to solve the comparing categories type of question.

I have developed three different strategies for them to use to solve:

1. Turn it into a subtraction problem to find the difference.
2. Draw and connect partners with the data and find how many are left over that do not have a partner.
3. Compare the two categories visually and see how many extra there are in the higher category.

Connecting partners always seems to work because it is concrete and they can see the partners circled and matched together. It is more difficult for them to immediately design a subtraction problem from reading the question, but with practice they will begin seeing the connection.
