I have an observation teaching interview tomorrow morning. I get to teach language arts for 45 minutes, and then math for 45 minutes. Only 8 kids, all girls, fifth and sixth grade mixed ability. They are working on fractions in math. Those are my only pieces of information. Any ideas for a fraction lesson? I want it to be hands-on, inquiry based. I have no idea what they already know, or what they don't. I do know one girl can be a bit slow at grasping concepts, and one girl is already doing 7th grade algebra, so I have all different learning levels. This is a bad night to be working on this-I got the call about 2 hours ago, and I'm leaving in an hour to go to dh's work even all night in the city. I'm panicking a bit-any math teachers who can help me out??
