Good Lord, don't they teach any History in school these days. I'd have imagined they'd portray his election as the Second Coming, if that weren't so non-PC. :)
You've got an Internet connection, Google him.
But just in case you *really* need help, FDR stands for Franklin Delano Roosevelt, cousin of the real President Roosevelt, Theodore (Teddy).
< Actually FDR was a pretty good wartime leader, knowing enough to know that he didn't know squat about things military, and mostly leaving all but Grand Strategy, which is more political than military anyway, to the Generals and Admirals.
FDR had many bungles in his administration. His huge failures in WWII i.e., He took no responsibility for the failure to foresee Hirohito’s attack on Pearl Harbor even though he was warned that it was a possibility before it happened. Also he was the major delay in engaging the Nazi’s which allowed Hitler to rise in Power. The Jews and Europeans that were fighting to defend their freedoms were dying by the thousands before he even raised a hand to help and he may not have even got involved since he liked protectionist policy and was isolating the U.S. as Hitler burned Europe. Had it not been for the Japanese attack on Pearl Harbor, which made him realize that the threat posed on this country was Existential and that he could no longer count on defensive deterrent strategies to hold back Hitler and Hirohito then and only then did he choose to act. Had his Generals not come through for him and had the American people not risen to the challenge there would be a Thousand Year Reich and most of America would belong to Germany today.
Further it was the Marshall Plan which had nothing at all to do with FDR that built the long term success in Europe and Japan. FDR like most liberal politicians was a great Con Man that used Change and circumstance to promote his Career at the expense of American Freedom.
