I have a team in my class who is often does not have an answer ready when I
ask for them during activities. These are almost always "make a choice"
activities or ones where I ask them to write their answer on the board.

I'm not sure what to do. I tried calling them on it but it didn't work (e.g.
"Team 4, you didn't put your response up. What did your team talk about/what
answers were you stuck between?") but they fumble around and don't really
answer.

I don't grade the group activities during the unit (they are framed as
practice - most days students turn in something on their own (reflective
writing, the choice they would pick before talking with their teams) but
think this might be the only way to get them to get their gears together. 

Any ideas?
