We went to West Hancock yesterday. The children were working on math when I came in.  They kind of got distracted at first but then got back on task.  All the children had their one-hundred chart and an expo marker.  She would write down a problem like "30 is 10 less than what number" the students had to circle 30 and draw an arrow to the number it was less than.  The answer was 40 but students were putting 20 because they were getting confused with more and less.  I had to walk around and make sure they understood. They were all excited to get help from me.  When lunch came around I redid their bulletin board.  I also made copies of their test. when I got back I had enough time to staple all of them and then it was time to leave.
