The activity presented to the teachers asked them to find the answer to a simple fraction problem. When asked how they got the answer they said "I found common denominators and multiplied." The facilitator then asked them to prove how that works; this is where teachers found the problem to be difficult. This opened the activity to other activities all throughout the mathematic spectrum. With these activities teachers realize the most important part of a math problem is discovering how to do it, not the answer to the problem. Learning for understanding is important to teachers also, not just the students. Teachers also need to reflect on their teaching experiences that way they have a better understanding of what to teach and how to teach it. In the end, learning is not a one step process its an entire circuit of questions, answers, and discovery.
