Just before we begin adding and subtracting large numbers, the students are demonstrating their understanding of large numbers. The curriculum asks them to be able to use numbers up to 1000.

If your child has not mastered basic addition and subtraction facts, now would be the time to start reviewing and working towards 'knowing them by heart." It will make a huge difference as they work through larger numbers.
