To use measurement to demonstrate division.
a meter stick
a ball of cord
a pair of scissors
Seat the class in pairs. Have one student measure and the other cut.
1. Measure and cut a piece of cord 110 cm long.
2. Start at one end of the cord and cut pieces that are 8 cm long.
Cut as many pieces as possible. Measure carefully.
3. Count the number of 8 cm pieces you have cut.
4. Measure the piece that is left over. It should measure 6 cm.
Repeat the process for other lengths of string.
110 / 8 = 13 r6.
For each division sentence, make and complete a table showing:
1. Length of single piece
2. Length of single pieces to be cut from single piece
3. Number of exact-size pieces that can be cut from single piece
4. Size of left-over piece (the remainder)
5. Division sentence (Give the division sentence this represents)
Repeat for the other examples.
