... How do I do this? Students are given cards with numbers, variables and symbols on them. An equation is placed on the board. X + 7 = 10 d – 8 = 9 a + 2 = 11 Students will model the equation with their cards in the front of the class. ...

... 1. Sometimes backtracking doesn’t work. For example, in the equation 3t + 12 = 5t + 6 there are variables on both sides of the =. We can’t backtrack this because we don’t know the result. 2. We can solve the equation by using a number line. (from p. 138) ...
