What's the Problem?
Continuing the Investigation
Have partners create stories and trade them.
Each partner can then write a number sentence
to go with the other partner's story.
Have students sort the number sentences they
have made into categories: e.g., those with 0
whole number solutions, those with one whole
number solution, those with two whole number
solutions, those with infinite whole number
solutions.
Have students try to find an equation or
inequality with exactly 0 whole number
solutions, exactly 1 whole number solution,
exactly 2 whole number solutions, more than 5
whole number solutions, etc.
