I wanted students to be able to focus on the attributes of 2D shapes without depending on the “it looks like this, so it must be this shape” mindset. ![]() The type of reasoning that is required to be able to classify objects and make accurate generalizations about each group is a thinking skill that will serve students well down the road. While these standards may not be considered core work for 5th grade math, I think of these as the ultimate critical thinking standards for students. This just means that students are using a visual representation to thoughtfully organize the ideas and groupings students discussed in the previous standard. Standard CCSS 5.G.4 takes this a step further and asks students to create a hierarchy of two-dimensional figures based on their properties. In 5th grade, students are expected to group figures based on their properties and begin making generalizations or statements about all figures in these groups. ![]() It can be the number of sides, the length of the sides, the size of the angles, or whether or not the sides are parallel. Common Core standards 5.G.3 and 5.G.4 (or whatever the equivalent of these are for your state) are a continuation of work students did in 4th grade when they started talking about the attributes of shapes.Īttributes or properties of shapes are the things that make shapes different from one another. ![]()
