My 7yo finally got his multiplication facts down

Been drilling these with him since September and honestly thought we were fighting a losing battle. Kid would get frustrated, I'd get frustrated, whole thing was a mess. But last week he just... got it? Like the light bulb went on. Now he's flying through his math worksheets and actually ASKING to do more problems. His teacher sent home a note saying she noticed a huge improvement too. Feeling pretty proud right now not gonna lie.
