Picnic Time
Use a shopping brochure and purchase some items (at least 10 - you to be well-fed) for a picnic. Your items must all have decimal numbers.
- How much did you spend in total?
- Check your answer, using estimation and rounding (e.g. rounding to the nearest dollar or 10 dollars for each item then adding them up), is your answer reasonable?
- Now check it with a calculator.
