The check out counter is where we commonly
think about math in the grocery store.
It's where the total is
added up, the money is exchanged, and the change is returned.
What
you'll need
All the items you intend
to buy
What
to do
1. Have your child
estimate the total.
2. Ask, if I have 10 one
dollar bills, how many will I have to hand over at the checkout?
What if I have a 20
dollar bill ? a 10 dollar bill ?
How much change should I
receive? What coins will I get?
3. Count the change with
your child to make sure the change is correct.
One way to make
estimating totals easy is to assign an average price to each item.
If the average price for
each item is 25 cents and if you have 10 items, the estimate would be
about 2.50
PS: Consider doing more fun printable
math activities.
