We had our co-op today, I was leading and between that and Annika I didn't get to take many pictures during the actual lesson. But I thought it was a lesson worth sharing.
The topic was fish. My boys requested to learn more about them- technically they wanted to learn more about their fish- but I couldn't think of good group activities revolving around Raphael and Pictus catfish, a peacock eel and knife fish amongst others...so I went with a lesson I found online about fish of the great lakes.
We started with a discussion about what a fish is and how they can be classified. Then I gave each group of kids a set of 12 cards to sort in anyway they wanted. We had 3 groups and each sorted different ways- by fins, by color pattern and by tail. We discussed other ways they could have been sorted as well.
Then I gave each group a dichotomous key for the Great Lakes Fish Families. We talked about what a Dichotomous Key is and then they went through their 12 fish and tried to id which family it belonged to using the key. They did good- and classified them mostly correct.
Then we sorted the kids by making our own dichotomous key. We started with the question: Is the person a boy or girl? And kept on asking until we had identified everyone. Using characteristics such as hair color, glasses,earrings, eye color- and in the case of my boys who all have blonde hair and blue eyes- clothes patterns and lack of front teeth.
