Mrs. Giacona is having a dinner party tonight at 7:00. She must
go the grocery store and buy the ingredients she needs for the
meal.
She drives 45 mph to the grocery store,
chooses her items and goes to the check-out line,
checks her watch to make sure she's not running late,
and gets home to put dinner in the oven.
Numbers are everywhere!

can be used for communication also. |
