Equation Solution Counter


#1

Randomized equation with correct solution counter


#2

Jay, I’m wondering if it’s possible to recreate this activity in several different ways:

  1. If we replace the = in the equation (and answer) with a <, how do we code to check for correctness? (especially if we change the original problem so that the coefficient of x might be a negative number).
  2. (Our long term plan is to randomize the original problem to switch between <, <=, =, >=, and >).

#3

We don’t have a really good way to work with inequalities yet. The best example so far would be something like point collector: lines, however, that activity uses raw expression which can be tricky.

I’ll draw up a rough example and get back to you.
