Quick Images (Using Dot configurations)

Shumway mentions Van de Walle's book, Elementary and Middle School Mathematics, on page 52. After Googling his name, I found this video slide show and it moves pretty quickly through a series of dot configurations. There are plenty more where that came from! My first thoughts were of fluency, after the students know the routine well, and perhaps even for individual or small group choral practice. It's a great example of how a Quick Image routine can be used for enrichment as well.
Quick Images (Using Ten Frames)

I must admit that my favorite part of this video clip was how the teacher reacted to the student who called out his insight. When she changed her board around, he noticed that she did not add or subtract magnets so it must still be eight. I love her reaction and must remember to do the same the next time I am in a kindergarten classroom.
Rekenrek Demo

There has been much discussion surrounding rekenreks recently since the majority of us haven't personally used them. This is a great (and brief) demo of the math concepts rekenreks can reinforce.
I noticed in a few other videos I browsed that the teacher was allowing the students to sketch what was seen on a white board or paper. Then the students were given a second quick look to double check. The idea of double checking their thinking appealed to me because as teachers, we're always trying to do that and this was an easy way to work that into a classroom routine.
The other observation I made both during the reading of the chapter and watching the videos was the amount of time the students were allowed to discuss their observations. This cannot be overstated. Children must, must, must have a chance to discuss their ideas and learn how to listen to someone else's ideas well. It takes time and practice but I know adults who are still learning how to listen so....
Discussion Questions:
Q1 What have your considered adding to your classroom to give your students that much needed "multiple exposures" component?
Q2 What have you already started in your classroom to build number sense?
