### Friday Freebie! - Exploring Quadrilaterals

After two weeks without my computer, I finally have it back! Here's an activity I adapted for my class to compare and analyze attributes of quadrilaterals. This file includes 12 quadrilateral sorting cards, a chart for analyzing attributes, a page to draw in lines of symmetry, and an answer key.
This activity meets the following Common Core Standards for Mathematics:
• 4.G.2 Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size.
• 4.G.3 Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
• 5.G.3 Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.
• 5.G.4 Classify two-dimensional figures in a hierarchy based on properties.

1. Just discovered you and really like your unique blog. I'm passing on the One Lovely Blog award to you.

2. For some reason the link to download this is not working for me. Looks so cute, just what I need for my 4th graders.

3. Same here. When I click the link I get an error message.

Thanks!

4. Sorry all! I guess it helps when you make the documents public! The link should work now. Please let me know if you still have trouble downloading.

5. Thanks, it works fine now. Very nice activity.

6. Thanks for sharing your awesome resources for my CCSS sites, but I can't add blogger images to the linkys (inlinkz won't take them). Please feel free to use photobucket to redo your images and resubmit as I would love to add them. :) Thanks! Charity
