Today we were looking at how sometimes using a calculator is not always as useful. For example, 1/3 + 1/3 + 1/3 is 1 whole BUT if you complete this using decimals, it is 0.3+0.3+0.3 which is 0.9. This is called a rounding error. We used calculators to find patterns about this and used this information to create questions and checked them by playing quiz-quiz-trade.
