Great activity for having students develop their skills at estimating. Potential for developing their understanding of error analysis/estimating/measurement. Easy to play, and allows comparison to other players or comparison to their own plays.

Some interesting activities to do with the Smart board in a mathematics classroom. I tried a couple of the activities and I did like that students were asked to estimate and predict. If teachers had clickers in their classrooms, this would be a great way of getting students to predict, record and then predict again and use the clickers for more than opening bell activities.

Great new number sense math app. Cost $0.99 at this time but uses: the capabilities of the iPhone well (motion, graphics), multiple representations including linear and circle models, decimals, fractions, percents. Is fast moving and progresses beyond 0 to 1 to have students estimating values like 0.26 on a number line from 0 to 2.  

Great games to work on multiple skills, estimation, percent change, multiplication of decimals at multiple levels. I enjoyed the dart game!!! Can you beat 66.67% accuracy at level 3?
