Multi-Grade Geometry

By -
We are studying geometry in math. Four days of the week, we study geometry in multi-grade groups. We work to take notes on the attributes of different shapes and angles. Then we work to apply and extend our understanding through practice work measuring, drawing, and discussing.


The conversations we hear sound like this: "First Josh thought that it was less than 90 degrees, like 85 but then we looked at the angle and realized it was an obtuse angle and there's no way it could be 85 degrees so it's actually 105." Laura

One fifth grader commented, "This is hard!"


Students extended their study of geometry during word study. They are thinking about comparing and contrasting attributes of triangles and quadrilaterals. Students are challenged to use the following terms in their discussions: obtuse, acute, equilateral, isosceles, scalene, rhombus, parallelogram.



We are thinking about questions like these:

  • Are all squares rectangles? 
  • Are all rectangles squares?
  • What are supplementary angles?
  • What are complimentary angles? 
  • Are complimentary angles and supplementary angles related? If so, how?
  • How do we use protractors to accurately measure angles?

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!

More than One Way to Solve a Problem

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.
