Quizzical Quadrilaterals!

In our polygon unit we are learning about four-sided figures called

QUADRILATERALS!

Quadrilateral just means "four sides"
(quad means four, lateral means side).
Any four-sided shape is a Quadrilateral.
But the sides have to be straight, and it has to be 2-dimensional.


Many people were confused about why some shapes have more than one name. Here are some interactive quadrilaterals to help you explore and learn more!

    Dear Mrs. Ranney and Class,

    I have seen quadrilaterals in my house very often. I saw rectangles which were my TV remote controller and picture frames. I also saw many squares which were the tiles in my bathroom and my crackers.

    Dear Mrs.Ranney and class,

    One of my favorite quadrilaterals is a rhombus because it has 2 pairs of parallel sides and it has four equal sides.

    Best wishes,
    Francesca

    Dear Mrs. Ranney and Class,

    I see many quadrilaterals in my house such as my computer screen,the computer printer, the keyboard and even the mouse pad. I think that you can find quadrilaterals everywhere.

    Sincerely,
    Eve

    Dear Mrs. Ranney and class,

    I have more quadrilaterals around my house.

    My SD card, my cuboards, all six faces of my art supplies box, and the top of my stapeler are all rectangular. I'm looking forward to reading your comments tomorrow.

    Regards,

    Nicole
