Make them estimate logically!

One of the many "take homes" I picked up from my AVID summer institute conference was the need to really get kids thinking and making logical decisions. Each day, we participates in Estimation Station. I have incorporated this into my classroom and my kids ask about it everyday and look forward to Fridays because of Estimation Station. They even do this little chant! First, I find something the kids like for a treat to put inside a random, clean container. I have used skittles, m&m's, Oreos, Mike & Ike's, etc for treats. For containers, I have used disposable, cheap containers from the dollar store. Containers that are unusual get the kids intrigued and excited. For example, I used an unused picnic-ketchup container this past Friday.

 The treat and container are only the hook. I ask my students to estimate the number of items, the weight in ounces, the length if connected end to end, and the ratio of red skittles to the entire number of skittles within the container. These are just a few of the estimations I have used but so many more could be utilized. I realize that kids do not have the schema to make an accurate estimation for some stations. As a result, I provide samples to give them some background knowledge. We discuss the weight of a stapler, a baby, a shoe, a desk, etc. Conversion is also incorporated into this activity that students deem "just for fun."

 Students put their names and estimations on sticky notes and put them on my doors. Then, I require them to write about the process and their rationale. Frantically, they write about this exciting activity. They know that when they are finished we will be identifying our winner. The time comes and I try to play it up as much as possible. The kids all cheer for the winner and it is a great way to end the class on a Friday. Monday morning, we begin by scrutinizing our writings. Where they over or under in their estimation? How could they have been more accurate? These are just a few of my questions. However, students are eager to be perfect their estimating skills. Finally, students offer future Estimation Stations which is great because they continue to buy-in to the activity, feel a part of the process, and offer some pretty amazing suggestions.

 I learned so much at the AVID summer institute but this small little activity really fit into my classroom routine and made it not-so routine!
