Today we continued to investigate the area models of mutiplication, but today we used chewing gum. We had to do a lot of thinking to figure out how many pieces there were at each table, in the class, and we made lots or rectangular arrays using the sticks of gum. Today we looked at rocks through the eyes of a geologist. We tested the hardness, luster, streak patters and cleavage or fracture of each rock. We will continue this in science lab on Monday. We also investigated how the tectonic plates move. We took graham crackers and frosting and practiced how the plates move by pulling them apart, pushing them together, and sliding them against each other. Students could see that mountains formed in the frosting. We also cut apart the continents and put them together like they were along time ago. We started reading a biography of Harriet Tubman. Students have a journal they are working on that will help us keep track of the interesting things we learn about her. We also investigated another memoir by Patricia Polacco. Students began writing their rough drafts of their own memoirs.
