1. Predict what will happen when a tape diagram has a large number of squares, some squares are removed, but then the same amount of squares are added back on.2. Build a tape diagram with 10 squares.
In every problem we did today, why did the final value of the expression equal the initial expression?
Initially, we added an amount and then subtracted the same amount. Later in the lesson, we subtracted an amount and then added the same amount. Did this alter the outcome?Why were we able to evaluate the final expression even when we did not know the amount we were adding and subtracting?
