Google Slides for helping students estimate prices
The Google Slides (link at bottom of page) has an editable text box to allow educators and parents to enter items for estimation (below, top). Several items can be included in a single Google Slides (below, bottom).
If a student has an unreasonable response, a follow up activity can be provided. In the follow up, the student shops online for 3 different examples of the item (below, top). In the example at the bottom, the student had reasonable estimates for shoes and a laptop, and was tasked with shopping for candy bars and a bag of chips. After multiple sessions, the student began to estimate candy bar prices in the low single digits.
