I 'm always keeping an eye out for opportunities to give my daughter a bit of practice with math and show her that math is useful. This morning we finished the first chapter of a book (West Meadows Detectives: The Case of Maker Mischief). She looked at the number at the bottom of the page and remarked: "We read 20 pages." I said: "Well, no, because the story doesn't usually start on page one." So we looked, and sure enough, the text of the first chapter of this book started on page seven. She was quick to tell me that we had read 13 pages. (Technically, we read 14 pages, because we read pages seven and 20, but I didn't see the need to get into that right way. That will be a topic for another day.)
We attempted a similar calculation when we started reading a storybook collection with a table of contents (Biscuit's Christmas Storybook Collection), but the numbers weren't as easy (page five to page twenty-one), and so we dropped the effort for now. But I intend to try this again.
Page numbers and book chapters provide a natural opportunity for practicing subtraction. Obviously, I wouldn't want to turn every reading session into some sort of drill concerning number of pages. But if you have a child who is achievement-focused ("How many pages did we read today, Mommy?"), I don't think that there's any harm in using page numbers for a bit of extra math practice from time to time.
What do you think?
