RAFT Hands-On Education

Don’t lose sleep over this, but Daylight Savings Time (DST) is here! On March 11th it's time to set your clocks forward and say goodbye to one hour of sleep! There’s no time to waste! Make this year’s Daylight Savings Time an engaging and meaningful experience for you and your students. RAFT has plenty of ideas to help you and your students get ready for DST:  “ Time for Shadows ” shows you how to quickly assemble an equatorial sundial that you can quickly adjust for daylight savings time! Learn about sun positions and shadows with drinking straws, a protractor, a compass, and a CD! Use a view binder cover, a watch, a paperclip, straws, the compass, and other easily accessible resources to create a “ View Binder Sundial ” similar to the one our forefathers used to tell time before clocks were invented! Create a sand timer (based on the concept of an hourglass), and learn how to measure time with “Sand Timer Primer.” Why do we have Daylight Savings Time?...

Did you know that each year on December 4 th in the United States people observe National Dice Day?  Many games use dice as a way to add random challenges by generating numbers from a toss of the dice. The value of the toss is determined by the uppermost face of the die after it has come to rest.             Dice are used as  gambling  devices for games like Craps and are also used in non-gambling  tabletop games. Dice are often used in board games to decide the distance a playing piece will move on the board.  Backgammon and Monopoly are two such board games that use dice.           A traditional die is a  cube , with each of its six faces showing a different number of dots ( pips ) from 1 to 6. When thrown or rolled, the die comes to rest showing on its upper surface a random integer from one to six, each value being equally likely. A variety of similar ...

“Time and Tide waits for no man.” This famous saying comes to mind when it’s time again to set our clocks forward on March 11th 2012, and lose one hour of sleep! Why is there Daylight Savings Time (DST)?  Basically it is because many people want to gain additional daylight during the early summer evenings.  So, clocks are advanced forward by one hour in the spring, and in the fall, are again set back one hour (the phrases “spring forward” and “fall back” help you remember this). As we get ready to work on the hour hand on our clocks, Resource Area For Teaching (RAFT) takes a look at many, fun hands on educational activities based on RAFT Idea Sheets that you can use to innovatively teach your students the concept of time. With the RAFT ‘Time for Shadows’ Idea Sheet activity you can quickly assemble an equatorial sundial that you can easily adjust for daylight savings time. With just drinking straws, protractor, compass and a CD, your third and fourth graders can cre...

Come meet RAFT ’s Math Activity Developer, Jeanne Lazzarini, at RAFT San Jose who has a treasure chest of Pi-Day activities to share!  Not only will she be dressed as a Pirate (because Pi rates!), she’ll also offer you delicious pie to eat while showing you great Pi-Day Math activities to make and take, to use in your classroom to celebrate Pi day! The Pi-Day activities include RAFT Math Idea Sheet activities like Finding Pi , Wearable Pi and Pi Day Pin . Irrational number Pi, also written as π, is the ratio of the circumference of a circle to its diameter, and is celebrated all over the world on March 14th because π is a number that begins as 3.14!  With the use of computers, Pi has been calculated trillions of digits past the decimal point!
