|The kids brought these in from home. |
|We decided that they should use the rulers they were going to have to use on the state test. The 7-inch rulers were not up to the task of measuring the heights and the widths of the boxes, but Rich and I decided that was OK...|
|...they would figure it out.|
I was most excited to use the opportunity to revisit an area model for multiplying fractions and mixed numbers, so we had the kids outline the area of the bases on square inch grid paper.
|7 1/2 by 2. We had originally thought they would do it on blank paper. But we decided the grid paper was better because it more effectively expressed the idea that the fractions were pieces of actual squares.|
This continued for several days. They got a lot of practice working with fractions, multiplying, dividing, and measuring, and the fun was just beginning... because now they would have the chance to create their own cereal, and design the box.
|Drawing a three dimensional shape on paper presented some challenges. This student's ingenious use of two rulers gave Rich and I the idea that protractors could be used to make the representations even more accurate. Duly noted for next year.|
|Nike is into everything these days.|
|Love the mascot!|
|For the One Direction fan in all of us.|
|Check out the expiration date.|
|This is a "mini-box". Each group had to come up with one that was half the length, width, and height of their standard sized box.|
The kids loved it. There was a high level of engagement, great collaboration and problem solving, and a nice blend of computation, measurement, and geometry. As we put the projects away (we're not done with them yet!), and headed into the week of the NJASK, my one thought was: That's the kind of test prep I can believe in.
