Have you ever stopped to think about how the movement of an object affects its shape? Our class is well into our new math unit called Flips, Turns, & Area where we are investigating how objects change when they are moved by a series of "slides", "flips" and "turns". Visualizing how different shapes fit in space is an important geometric skill many of us use everyday. Suppose you make roll-out cookies with your child. This poses a problem of area. How can you place the cookie cutters so that you cover the most area and have the least amount of dough leftover? Do you have to rotate the cookie cutter to get the best fit? I remember moving into my house a few years back and having to turn chairs sideways to fit through the doorway. In class we are practicing these skills by playing a game called Tumbling Tetrominoes where students have to think ahead and plan strategies to make different 4-square arrangements to best fit an area. I'm encouraging each student to get extra practice at home. Just click on the link and download the game. Enter the password..."Douglas" (no quotation marks, capital D). Students can play using different sized game boards and score is calculated by subtracting the number of empty spaces from the number of possible spaces. We are concentrating on using 120 square-unit game boards so a score might be 120-8(unfilled spaces)= 112. Students can bring us their initialed score sheets for Chance Tickets in the classroom! Have fun!
