Open Area/Perimeter Grid

I can create a measurable polygon to show area/perimeter with clear illustrations, units, and labels. Tap add to begin. Use the drawing tools to create a polygon and annotate for explanation. Optional and encouraged: Consider matching ink and label colors. Use the label tool to for side lengths including units. to explain and use other tools during recording. Post your work

Teacher Notes (not visible to students)

Consider using the three dots to copy and edit this template to more precisely meet your desired learning targets. MN Math Standards: Geometry & Measurement 3.3.2.1 Use half units when measuring distances. 3.3.2.2 Find the perimeter of a polygon by adding the lengths of the sides. 3.3.2.3 Measure distances around objects. 4.3.2.3: Understand that the area of a two-dimensional figure can be found by counting the total number of same size square units that cover a shape without gaps or overlaps. Justify why length and width are multiplied to find the area of a rectangle by breaking the rectangle into one unit by one unit squares and viewing these as grouped into rows and columns. 4.3.2.4: Find the areas of geometric figures and real-world objects that can be divided into rectangular shapes. Use square units to label area measurements.
