Rectangle of pentominoes |

rectangle outline |

For the activity, I divided the students into groups of 3 or 4. The directions for the activity were not complicated - the task was to make a rectangle, using all of the pentominoes. I gave students an outline of the rectangle, as pictured to the left, so they would know the correct size of the rectangle. The squares in the grid are each one inch. The rectangle is 5 squares (inches) wide and 13 inches long (13 inches includes the row that has the "Pentominoes" title.)

We spent about 15 minutes with the pentominoes; some groups were able to make the rectangle and some groups were not, but all groups (in all 4 classes) were persistent for the entire time. This is the type of activity that allows all students to persevere, regardless of their background knowledge in math. All students could manipulate the pentomino pieces and offer suggestions, and while some students are strong in certain areas of math, others are stronger spatially; this introduction activity allows them to have success.

As students left class, I heard positive comments - "That was fun," "I wish we had more time to figure it out," "Can we work on it again tomorrow?" To me, the activity was successful - students persevered, worked very well with one another, and left with a positive attitude.

Throughout the year last year, I did give students opportunity to collaborate to solve various types of problems, and they always worked well and seemed to enjoy those classes. My goal this year is to incorporate more (and better-constructed) activities of this type.

What first day activities have worked well with your math students?

ReplyDeleteI'm sorry, I don't. I did add the picture of what I give the students, and a brief description, if that helps. Thanks for asking:)
