Click on a box below to find helpful websites to support the indicators taught in this unit. The indicators are color-coded and the websites numbered to assist teachers in directing students to the correct site. These websites are intended for the wide range of students in the grade, therefore some may tend to be easier and some more difficult. These web pages may contain links to one or more pages outside the MCPS Web. MCPS does not control the content or relevancy of these pages.

General Math Sites	2.3.1.2 identify, describe, and classify common three-dimensional geometric objects (including cube, rectangular prism, pyramid, prism, sphere, cone, cylinder) and relate them to their two-dimensional counterparts (square, rectangle, triangle, circle).	2.3.1.1 identify, describe, and classify polygons, including pentagons, hexagons, and octagons.
2.3.3.1 draw geometric figures using tools and technology.	2.3.3.2 construct with blocks a solid to match a given picture or model.	2.3.2.1 identify right angles in geometric figures or in the environment.
2.3.2.2 determine whether angles found in geometric figures and in the environment are greater than, equal to, or less than a right angle.	2.3.4.2 identify, describe, and represent symmetry of geometric figures and real-world objects.	2.3.5.1 identify, describe, and represent congruency of geometric figures and real-world objects.
