Beach Day!

This week we were given the task to go on the balanced assessment program webpage and find a assessment that fits our standard. My standard is CC.2.1.2.B.1,  using place-value concepts to represent amounts of tens and ones and to compare three digit numbers.
Which means children must be able to understand place values in three digit numbers. They also must know how to represent tens place, ones place, and hundreds place. The assessment that I found that was closest to my standard was Beach Day. Although, it did not compare three digit numbers, it requires children to understand place value in the tens and ones place.

The assessment had various temperatures and asked what day would be the best day to go to the beach. The child would then have to depict the hottest day by knowing what value each number held. The child would them have to explain why the other days were not ideal to go to the beach.

I think this is a good lesson but not completely for my standard. With this assessment we are pulling science and math together which I think is a great idea however, I would change a few things to have it better fit my standard. One thing I would change is that I would have them subtract two temperatures to get one days temperature. For example, Fridays temperature would be 130F-46F=84F. 84F would be the temperature for Friday. I would do that so three digit numbers would be reviewed along with subtraction.
