Long Division

Help the Poor Math Student  Pick a student that will play along well. Take them into the hallway and tell them to “Play Dumb” and know nothing about math. Asked them to come back into the class, and instruct the class to help the “dumb” student work out the long division problem.

Vocabulary Dividend: number being divided Divisor: number you are dividing by Quotient: is number you get when you divide Remainder: the number left over if it does not divide evenly Factors: the DIVISOR and QUOTIENT are FACTORS if there is no remainder

Steps for Dividing Have students try to come up with steps for long division, or skip this slide and use the graphic organizer.
