We will be working with the number zero in the Mathematics and Science Centers again. After reading, ask the students if they think some of the author's ideas about dinosaurs could be true. Tell students that they will be writing their stories about extinction at the Writing Center. In our first activity we will discover more about dinosaurs. Procedures Children go outdoors, if weather permits, otherwise use a hallway.
Children hypothesize as to the size of dinosaurs.
Students compare the chain to their own heights. They estimate how much food a dinosaur like the one they measured would need to eat every day. Yes, you put them side by side to compare. At the Mathematics Center, the students, working in small groups or in pairs, classify the dinosaur models by color, size, and shape, after describing them to their partners count a given number of dinosaurs to place under the correct numeral written on the sorting trays say how many dinosaurs are alive now and point to the numeral that tells that number, and continue sequencing the dinosaur shapes. At the Library Center, the children continue to read and look at the new book that was read for this lesson.
