This is a little out of the ordinary for those who frequent my blog, but here is something that my wonderful wife and I use to help our children learn math. If you did not already know, we homeschool our eight children. We are not big on math drill; we think word problems teach reasoning far better. But to do word problems effectively, the ability to have instant recall of the 100 math facts in addition, subtraction, multiplication and division is crucial.

We have our children work at it until they can get it perfect in five minutes in third grade, and three minutes in fifth grade.

To use the spreadsheet (right-click and use “save link as” to download), select the tab that you want to work on. “little add, and “little subt” are the 64 math facts with no number greater than 10. To use the sheet, hit the F9 key to recalculate the sheet, which places all the problems in a new random order. (You’ll never get 2 sheets the same.) Then hit the print icon. F9, print, F9, print, etc… pretty soon you’ll have a lot of unique sheets for drill purposes.

Use and distribute as you see fit. I just want to see children who are good with their math. And, if it works for you, let me know.
