This lesson is designed to help students with addition.
Students will solve word problems relevant to their experiences that involve
Students will participate in a game involving addition using
the phenomenological approach.
Dry wall tape (available at hardware stores)
Paper and pencil - scissors
Metric ruler - meter stick
Random number generator - dice or spinners
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.
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.

expertise and sharing his own personal materials.
