# Keeping Track Of The Grocery Bill When Shopping

I usually have my grocery list and check off items as I put them in my basket. Instead of a calculator, I just put a slash mark on my grocery list, for the price of the item, rounded out to the dollar. At checkout, I quickly add up the slash marks that are in groups 5 and I'm usually within \$3.00 of my final bill.

I do something similar, I keep a running total, rounding up to the nearest 10 cents. For instance if something is \$4.78, I round up to \$4.80. By the time I get to checkout I am usually within a dollar of my total.

Great to hear that someone is using math skills rather than electronics. I teach rounding and estimating to my grade 7 & 8 classes, and this is the sort of thing that I tell them that people can do -- a practical use for the skills that they learn.

Good idea. When I'm waiting in a grocery line, I mentally add up the total for my groceries, and am usually within 20 cents or so. At Aldi's it's easy because a lot of prices end in 9, so I just round it up to 10, and then add up the number of items I have and subtract that many cents from my total. It's good, practical mental exercise.

I use a tally counter.
