Dear Parents,Our math class is calling for students to be actively engaged in doing math in order to learn math. In the classroom, students will frequently work on tasks and activities to discover and apply mathematical thinking. Students will be expected to explain or justify their answers and to write clearly and properly. Your students have a consumable textbook and online access.

Concepts Students will Use and Understand

- Identify similarities and differences among two-dimensional figures.

- Reason about attributes (properties) of two-dimensional figures.
- Have experiences discussing the property of two-dimensional figures.
- Build upon their fourth grade knowledge and create a hierarchy diagram
- Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category

**Two Dimensional:**A measure in two directions, such as length and width.**Angles:**The figure formed when two rays or line segments share the same endpoint.**Point:**An exact position or location.**Line Segment:**A part of a line that includes two points, called endpoints, and all the points between them.**Perpendicular Lines:**Lines that intersect to form right angles.**Parallel Lines:**Lines in a plane that never intersect.**Base:**A polygon’s side or a face of a solid figure by which the figure is measured or named.**Quadrilateral:**A polygon with four sides.**Parallelogram:**A quadrilateral (4-sided figure) that has both pairs of opposite sides equal and parallel. Example: all rhombi (plural for rhombus). Squares and rectangles are parallelograms.**Irregular Polygon:**A polygon that doesn’t have all equal sides or all equal angles.Try http://intermath.coe.uga.edu/dictnary/homepg.asp or http://www.amathsdictionaryforkids.com/ for further examples.
