I know I answered on your other thread
But I couldn't remember if I said that we use our memory work box for everything we need to remember-Bible verses, times tables, irregular verbs, latin declinations, everything. I actually bought a big pack of stuff form "homeschooling with index cards" and we use a lot of that stuff in our memory boxes. I like how easy it is after I bought the packs-print and you're done.
Then I figured out how to make some of my own in word and now we have individualized cards, too.
And, we use the bigger postcard size-4X6. I found the index card size was just too hard to read when we started putting more info on the card; like the Lord's Prayer. The text was too small for the youngers to read, and the cards were harder for them to handle with their small hands, kwim?
I love, love, love the system! It's very easy to use. We started out putting all our cards in daily and then as they learn them putting them back in the odds, then evens, then days of the week, etc. We don't have any in the numbered sections yet, but we just started a few months ago. I'm looking forward to the day when the box is busting at the seams!
