Today we talked about precipitation in math. Students watched a short video clip (check out our Blackboard page!) about rainfall in the rain forest. Next, they paged through almanacs to gather information about monthly precipitation totals in a particular rain forest and in Pennsylvania. This helps give a better idea of how much rain really falls in tropical regions! Students made graphs to represent the rainfall for the months. Together, our class calculated the mean or average rainfall for each month in a rainforest and in Pennsylvania. Students should be able to explain to their grown-ups why knowing each month's precipitation is sometimes better than knowing the average. Check out the class blog to see students' great ideas! We projected them on the smartboard in class and we were able to highlight some of the important parts of a graph.
Keep in contact :-)
