Estimate Tim grew 4,799 carrots and nancy grew 3,699 carrots this year. Approximately how many carrots did they grow together?

They both grew 8,498 carrots.

Remark

You must do this without the use of a calculator. If you give 8498 which is what you get using a calculator, I would guess that you would be marked wrong.

If you can add 48 + 37 in your head, that would be a pretty good estimate.

Those two numbers added together give 85, so the answer to the estimate would be 8500. That's what I would expect to see if I asked the question.

If you can't do that in your head, try 5 + 4 which gives you 9. So you would give 5000 + 4000 as your estimate which is 9000. That also would be acceptable if I gave out the question.
