A multilayer cake was cored for samples to measure and study the various layers of the cake. Many, many thanks to the science fellow working with our school (in the pi shirt).
Reflections from an elementary school teacher on the joys and challenges of the job.


I didn't use duct tape, but we put the pieces of construction paper on the floor. That allowed us to try it first with just half the class (both halves tried it in different parts of the room). Once they were able to do it several times we took it out to the hall to have the entire class do it. That was at the beginning of the year. I do team building activities all through the first week to emphasize cooperation and to foster community. We've done it again now as a part of math. We've looked at how the pattern works and how to explain it mathematically.Use the duct tape (or masking tape) to make a starting pattern on the floor.
Have the participants stand in the boxes of the pattern: half of the group faces right, half of the group faces left.
Explain the task: Using only legal rules, people on the left side must end up on the right side and the people on the right must end up on the left.
Legal Moves
A person may move into an empty space in front of them.
A person may move around a person who is facing them into an empty space.
You CANNOT:
Move backwards.
Move around someone facing the same way you are.
Make any move which involves two people moving at once.
But surprisingly there was no similar divide in school performance or cognitive test scores.
"Improving nutrition in early childhood led to substantial increases in wage rates for men, which suggests that investments in early childhood nutrition can be long-term drivers of economic growth," they conclude.
So, what is my responsibility? Should my students be completely unaware of issues I face? Should they know if I'm having a bad day? Does their age matter, older students being more able to deal with understanding their teacher's mood swings or such? Is it my job to teach my students well regardless?I haven't really been able to figure out where I stand on this and I'm hoping for some thought-provoking ideas.
