`Number Addition RaceJanice Schaults                Randolph Magnet School                               7316 S. Hoyne                               Chicago IL 60636                               (773) 535-9015Objective:This lesson is designed to help students with addition. Students will solve word problems relevant to their experiences that involve addition.Students will participate in a game involving addition using the phenomenological approach. Materials:Dry wall tape  (available at hardware stores) Paper and pencil - scissorsMetric ruler - meter stickRandom number generator - dice or spinners Strategy:Divide students into groups of four.  Each group will need the materials listed above.  Long tables or six to eight desks arranged into a rectangle make the play area.  Two students on one side of the table compete with two students on the opposite side of the table.  The first pair of students generate the first number for an addition problem.  Write the addend on paper.  The second pair of students will use a meter stick to measure the addend in centimeters on the drywall tape.  Write the measurement on the drywall tape.  The first pair of students will generate a second addend and write the number under the previous addend.  The second pair of students will measure this amount on the same strip of drywall tape adjacent to the first measurement.  Write the measurement on the drywall tape.  The first pair of students adds the addends to find the sum while the second pair cuts the drywall tape and measures the total length of the strip.  THE MEASURE OF THE DRYWALL TAPE SHOULD EQUAL THE SUM OF THE ADDENDS.  If the drywall strip is measured correctly and the addition problem is correct, then the first pair of students receives the strip (tape drywall strip to the table starting at the edge of the table).  Play continues with the second pair of students generating the addends for the addition problem and the other students measuring the addends on the drywall tape.  The first pair of students to line the length of the table with the drywall tape is the winner.  This activity can be adapted to practice fractions and decimals.     Performance Assessment:Students verify the addition problem by measuring the addends on the drywall tape and matching the total length of the drywall with the sum of the addition problem.  If the students made a mistake in addition the other side will keep the drywall measurement and tape it to their side of the table.  Students will lose a turn if they incorrectly measure the drywall tape.Acknowledgement:David Drymiller, a member of the SMILE staff has been very helpful with his expertise and sharing his own personal materials.`
