What still needs work.
Groupings
This group was very big and completely made of girls. Although this sometimes works for them, this group was too big for what they were trying to do. Hence, some people didn’t actually do a lot.
Communication
The people in the group didn’t necessarily communicate well with each other. The two girls who made the material representation did it correctly, didn’t show the rest of the group then packed it away. If they had explained it to the group, it might have helped them solve their addition dilemmas a bit quicker/easier. Another girl knew what was written was incorrect, but didn’t say anything until I prompted her to do so. A smaller group would have made this a bit easier.
