Division and square roots

At the grocery store, C informed me suddenly that there are three 8s in 24. While we waited for our ride home, I put her through her paces in figuring out how many 11s are in 33, how many 12s are in 36, as well as having her do all the possible factors of 24 (except 24 and 1). My husband was doing something similar with her at bedtime with square roots. She was able to come up with 5 as the square root of 25 and 10 as the square root of 100 after the concept was explained to her.
