Reflection: Vertical Alignment Finding Rectangles - Section 2: Introduction to Finding Shapes


This is a task that can be challenging for first grade students.  It is not meant to be used as an assessment piece but rather used to to help students practice recognizing rectangles and trying to find as many as they can.  This is a precursor for the 2nd and 3rd grade standards: CCSS.MATH.CONTENT.2.G.A.1 and CCSS.MATH.CONTENT.3.G.A.1.
