TEKS Objectives
(9) Geometry and spatial reasoning. The student recognizes congruence and symmetry. The student is expected to:
(A) identify congruent two-dimensional figures;
(B) create two-dimensional figures with lines of symmetry using concrete models and technology; and
(C) identify lines of symmetry in two-dimensional geometric figures.

Resources
1. Eduplace.com. This is a great resource that will help students start talking in geometric vocabulary. By grade 3, students should be using geometry related terms in class on a regular basis. This website is a series of slideshows that takes you from one concept to another. The website explains sides and vertices. Moreover, the slides explain shapes and their properties.
2. http://www.literacycenter.net/shapes_en/shape_match_en.php. Literacy Center has assessments for students based on their skill levels. For example, students start from the easiest assessment and go higher and higher. Assessment is a very important tool for teachers because it lets them know how their students are progressing and if their students are struggling with the subject matter.
3. http://prek-8.com/3rdgrade/geometry5.html. Prek-8 has countless worksheets sorted by subjects and grade levels. By grade 3, students should be familiar with classification and combination. Students are expected to combine and separate shapes to form new shapes. Moreover, students are expected to understand angles that are formed within shapes.
