In math, my students are working on frames and arrows. I have been teaching them how to apply different rules to number sequences. For homework, they were given a set of number sequences, some with rules given and some with rules missing. Its a good way for students to practice applying addition and subtraction with a pattern. The students work I chose to look at has a "plus 5" rule. The first two boxes are blank, the middle box has 17, and the last two boxes are blank. The correct sequence should be 7, 12, 17, 22, 27, however this student put 27, 22, 17, 12, 7. Therefore, her numbers were correct, however their placement was not. I could see how she could be confused since she didn't know whether the numbers were going up or down on either side, but the arrows were going forward so she should have been adding 5 to left and subtracting 5 on the right. It was also interesting that she was the only student who put the numbers in that order. I would like to ask her about why she chose to put the numbers in certain positions to get see her reasoning. I would also give her a similar question and see if she did it again. I could provide her with more patterns to further her learning and explain that the direction of the arrows is an important thing to notice.
