I've been working with my grandson Isaac over the last few weeks. He's just turned nine. He has a computer-based series of lessons he must do each day after school. Each week is geared towards something they are currently learning at school in both Math and English language arts.
This week, we both got stumped by a lesson on prepositional objects. The computer program he uses is designed to tell you when you get an incorrect answer and explain in detail why your reasoning was at fault as well as showing the correct answer and the reason why its correct.
