Perimeter Game
Terms to Know:
polygon: a closed plane figure bound by straight sides

perimeter: the distance around a two-dimensional shape

What You Need:
•One deck of playing cards (Print a deck.)
•Metric rulers (scaled in centimeters)
•Pencils
•Paper
What You Do:
1.Shuffle the deck and place it in the center of the table. Give each player a pencil, a ruler, and a sheet of paper.
2.Players take turns drawing a card. They take the value on their card (aces = 1, all face cards = 10) and use it to draw a line equal to that many centimeters. They should label this line with its measurement.
3.In the second round, players will draw a new card, then draw another line stemming from either end of their previous line.
4.The goal is for a player to make a polygon by closing their figure with a final line on their third or subsequent turn.
5.When a player creates a polygon, they must also state its perimeter. If correct, they earn 1 point. On their next turn, they may begin drawing a new polygon.
6.The first player to earn 3 points wins.

News from Abroad and More

Postcards have been arriving daily from overseas and from our own great country. Becca's journal traveled to Memphis, TN and Orland, FL while Jessup's went from Alaska to Florida, Sydne's from Florida to Arkansas, Lauren's from Kentucky to Texas, and Ethan's from Las Vegas, NV to central Pennsylvania. Jack's journal was in China according to the last postcard he received. Mikella's journal must be especially weary as it flew from Norway to Australia and is now on its way to Scotland. All of the students love receiving word of their journals' journeys!

Literature Projects

Only two literature projects are left this year. Historical fiction is the genre due on March 26. Do not choose a book we have read together (i.e., Pink and Say.)
The historical fiction you choose should:
*present a well-told story that doesn't conflict with historical records,
*portray characters realistically,
*present authentic settings,
*artfully fold in historical facts,
*provide accurate information through illustrations, and
*avoid stereotypes and myths.

The final literature project for this year is the student's choice, but it MUST be a chapter book.

This week we are learning about clouds. Ohio fourth graders need to know how to identify cirrus, cumulonimbus, cumulus and stratus clouds. We will be observing the sky and recording our observations in our cloud journal.
