FIRST GRADE - Telling Time- stick a hula hoop to the white board, and write numbers around the inside of the circle to make a "clock". You can make little notches around the inside of the hula hoop to practice telling time to the exact time.
Laminate a number ladder, cut small slits in top & bottom & add a pipe-cleaner with a small bead. Use the bead to slide up & down as you complete addition & subtraction problems (",). could do the same thing with a horizontal number line.
