Times tables flashcards that skip the cards they already know
Flashcards are a decent first pass. They get messy once you are maintaining a hundred facts and only six still wobble, because the easy cards still eat the evening.
The pile gets worse as the deck grows
Paper decks and most apps shuffle every card into the same pile. Easy facts take the minutes, and the hard ones get one pass, same as everything else, so they never catch up.
Sorting cards into “got it” and “not yet” helps for a night. By Thursday the piles have been knocked over, a sibling used the table, or you were too tired at 9 p.m. to re-sort.
Where paper still earns its keep
If you like, use cards for the first exposure: say 6 × 7 out loud a few times while the idea is new. After that, ongoing review belongs in something that already knows each fact’s history, so nobody is manually sorting stacks.
What TimesOwl does
TimesOwl remembers Tuesday’s miss on 6 × 7, including how fast the hits were. The next session can skip the easy cards.
- 7 × 8
- 20 seconds
- 40 seconds
- 1 minute
- 3 minutes
- 1 day
- 3 days
A correct 7 × 8 might wait days. A miss shows up again in the next session or two.
Try five minutes before the worksheet.
They type a few answers. Open it on one device. A session is about five minutes.
