Before we dive into prenatal development, I like to do a little formative assessment to get an idea of what they already know, and what they think they know, and what they have so very, very wrong. For this activity, I divide them into groups and send them back to the kitchens (as I've mentioned before, this gives them lots of counter space, and gets them up and moving). Then each group is given a set of cards (color-coded to match their kitchens, of course!) that contain week numbers and a description of something that happens during the prenatal period. I ask them to work together to take their best shot at matching up the week with the correct description. (These really aren't the best pictures, but it gives you a little something to visualize.)
I then walk around so I can hear them discussing each item and where they think it belongs along the timeline and why. I get so much information about their prior knowledge, their thinking process, their communication skills... it's really a fantastic assessment! In addition to those benefits, it gives me a really clear idea about what misconceptions I need to work on clearing up as we go through the unit (and believe me, there are A LOT - but if you teach child development, you already know that!).
By the way, if you don't have white boards for group work, you absolutely must get some. The kids love them and they are fantastic for quick group work and all sorts of spontaneous activities. Love them!
p.s. Tomorrow's the big day for releasing oodles of materials to share!
