Procedures

1. Teacher passes out catalogs and announces that each child should imagine that they have been declared the winner of a $1,000 Grand Prize Thirty-Minute Shopping Spree.
2. Students use paper and pencil to list their purchases. Students are encouraged to use their estimation skills to check their purchases quickly. Students use calculators to check their purchases.
3. At the end of the thirty minutes, students must stop. Students reflect in their Place Value Journals as to the effect of using estimation strategies in a timed situation.

Assessments
