18. Extension Activity
Well hopefully you did okay on the quiz. In
a moment we will break into groups in our
class and we will spend more time
practicing what we have learned in the
lesson. You will be given a partner to work
with. Partner “B” will coach partner “A” who
will be answering the questions on paper.
Then when the teacher calls “switch”
partner “A” will coach and partner “B” will
answer the questions on paper. The
teacher will explain in person soon.
