- Identify and use memory and function keys.
- Identify any special features such as dual function keys,
rounding capability, parentheses, order of operations, etc.
- Enter and manipulate negative values.
|
| Objective B: Learners will investigate
mathematical patterns and relationships such as fraction/decimal/percent
conversions, multiplication tables, etc. |
|
| Objective C: Learners will solve problems with
calculator. |
- Choose correct operations and order in which numbers are entered.
- Use correct order of operations.
- Check for reasonableness of answer by using estimation, e.g., “While
at Penney's, Mary is considering buying two blouses on sale for
$27.95 each and a skirt priced at $34.50. She wants to pay cash for
her purchases but has only $110 in her purse. The sales tax in her
