Professional Development to Practice Incomplete Understanding  Students’ work shows they know something or have a partial understanding.  Student is ready for more instruction on that skill or concept.  Feedback or re-teaching is not the best strategy. Example: Students use a number line for subtraction but add the second number instead of subtracting. They know they can use a number line but are confused about how to use it for subtraction.
