Our START and SIGNET students have been busy!
First grade START has been learning about measuring area. We know that length is measured in one dimension and area must be measured in two. We've measured with square feet, square inches, and even square centimeters. This week, we had a classroom scavenger hunt to find objects that matched given areas. I was surprised to learn that most of the students can multiply, so we learned about finding the area of a rectangle using this math skill. Next, we'll be adding another dimension as we talk about measuring volume.
Second grade START has been learning about surveys and bar graphs. We've learned to use Microsoft Excel to create data tables, use built-in functions, and even generate graphs. Our big project is to survey four different grade levels and generate graphs of the data, then put together what we've learned in a presentation for the cafeteria staff.
Third grade START is also learning about area, but we've been working with irregular shapes. We've learned to partition shapes in order to find the area more easily. We've discussed how to find the area of both rectangles and triangles, and we've used the partition method to learn how to multiply two digit numbers by two digit numbers easily! We're learning a new vocabulary word each week, and our last word was juxtapose.
SIGNET students have been creating and testing rotor probes. Students were given a blueprint and had to use the blueprint to draw the probes at full size. We tested our creations, then changed our creations to see what factors affect the falling rate.
We'll be learning about circles and pi as we construct and test a second type of probe.
As always, our door is open! Please come by any time to see what the students are doing.
