This might be a good time to reinforce the fact that teachers do not expect everyone to “get it” the first time a concept is introduced and that students learn at different rates.  An analogy to cooking can be utilized.  Some students may need to “bake a cake”.  Teachers provide the “ingredients” (skills, tools or methods necessary).  The students mix it up in their brains and it has to “bake” for a while until it is “done” (internalized or learned).  Others are “making a salad”.  They can take the “ingredients,” briefly “toss” them, and they are ready to eat.  Some days are “cake” days and some days are “salad” days.  There are some days that the cake falls or the salad isn’t crispy enough and you have to try again.  But in the end, both the cake and the salad can be delicious!
