Reflection: Joy Is It Enough? - Section 2: Estimating How Much I Can Buy


Allowing students to design a robot to clean up an area they are fond of proved to be such a motivator. As the kids were drawing their robots there was an intensity about the project that is not always there. The students were very invested in getting out the yardsticks, rulers and meter sticks to see if their estimates were logical for what they were envisioning for the size of their robots.

Students also became so involved in figuring out how many of something they would need. They looked and realized they would need more than a foot of tape, or more than 3 pipe cleaners so they had to add the price more than once. It was great to watch how they went about figuring out what the total price might be for more than 1 of something.

The students saw a purpose for carrying out the calculations. They didn't just take the cheapest items because that would be easier, but instead they picked the things they really wanted and then struggled with the cost. 

Getting students involved in a project that is meaningful for them pays off in their investment in doing more complex math to achieve their goals. 

Someone asked me once if Common Core meant that lessons had to be dull and boring and all paper and pencil. I have to reply that it is just the opposite. In order to incorporate the many math standards, and to create math thinkers, the lessons have to be engaging, challenging and creative.
