Title: It's In The Bag
Description:
This lesson is a unique and fun way to review perimeter, angles, and types of adjectives. Students pick an object from the classroom that will fit in a paper lunch bag. They investigate their object and fill in the attached sheet. You can then make a bulletin board out in the hall by attaching the bag (with the object in it) below or beside the info sheet. Students can come by and try to guess what object is in the bag by looking at the info sheet. They can then check their guess by looking in the bag.
Standard(s): [MA2013] (3) 24: Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories. [3G1]
