Let's Go Shopping (Adapted from CBS Cyberchase)

.Students will use estimation skills as they round off to the nearest dollar while shopping at the local supermarket. Calculators will be used to add up the real dollar amount of items on a grocery list. They will then compare their estimates to how much they would have paid for the items in real dollars. Students will also use listening skills while watching a multi-media video on estimation. #VegasPBS-INST125
