Go Grocery Shopping
Grocery stores are a great source of spontaneous math lessons and a
great place to use the “think aloud” strategy:
Many stores have scales
available. As you shop
for fruit, stop and estimate
the weight of a bag of
apples. Use the scale to
get an accurate measure
in kilograms. Congratulate
yourself on the accuracy of
your measurement, or ask
yourself how you can improve
your estimate.
As wheel your shopping cart arouind,
keep a running total of the
cost of the items by recording
them in a small notebook.
Round the prices in order to
estimate, then check the total
with a calculator. How close
were you to the actual sum at
the cash register?
Select a variety of bottles,
cans and containers that hold
one litre of contents. Emphasize
to your child that,
although the shape may
change, the volume stays the same.
