Polygons and Perimeter!

By Anonymous -
The fourth graders are working on our fourth math unit: "Measuring and Classifying Shapes." This week, the students are learning how to identify whether a shape is a polygon. Students are also learning to describe polygons using words like "line segment," "vertex," "parallel," and "perpendicular."

Using hand motions to learn "vertex"
"Perpendicular"

Finding perpendicular and parallel lines in different polygons


Tracing polygons


Independently working

Before Thanksgiving break, students learned about perimeter. Students drew their names on grid paper and then calculated the perimeter of their name.

Almost finished


Looks good, Joey!

Students studied the rules for possessive nouns.  The placement of that little apostrophe changes everything! Students created cartoons that demonstrate the difference between singular and plural possessives. Here are a couple things we noticed about their work: The students' drawings are creative. Each student's idea is unique. Students have been completing projects in math. Fourth grade students are ordering fractions on a number line.   The fifth graders are working hard, too. Fifth graders are learning good note taking skills and are using that skill to inform their understand of reciprocals and the inverse property. All of this is part of their study of fraction multiplication and division. Students went to free cone day!

Have you ever used the Egyptian method for large digit multiplication? How about the Mayan? Did you know there were different algorithms and methods for solving these types of problems? Fifth grade math students did some research and created displays on algorithms from around the world. Students have been refining and improving their accuracy and efficiency with the United States standard algorithm   During our course of study, the Investigations curriculum asks the students to use at least two ways to solve multi digit multiplication problems. Many have relied on the box method. Because of this study of world algorithms, we have seen the students pick up more strategies to bring to their mathematical problem solving.
