Table 1 Mapping between Ollerton’s “Starting Point”, the planning discussion and “Card 1”
Ollerton 2002,
p. 1 Planning comments
Card 1
x+y=7 Starting point Ask everyone to write down two whole numbers that add up to 7.
Mari: If you give them that
(x+y=7) one can find two numbers each, in the group can find two, and so … they will have
different (pairs) when they put them together (T)
x+y=7 1. Each student write down two whole numbers which add up to 7.
What and how many different answers are there?
Mari: Which group can find the most [number pairs]? (T)
2. Can you find more such number pairs?
3. How many such number pairs can you find?
Turn the numbers into ordered pairs and graph them
Mari: There will be a [reward] for those who find the most points here!
Not points! Most paper numbers (T)
Liv: One must not imply that we shall have a straight line (T)
Kristin: Say it in a way that does not say anything about the thing that will be drawn. Hoping that some will possibly try to draw. (T)
4. Draw these number pairs on millimeter Not points! Most paper
