I went to grade school in the late 30’s just prior to WWII. I remember bouncing balls to rhymes similar to jump-rope rhymes. One in particular went “1-2-3- O-lari, 4-5-6- O-lari
7-8-9-O-lari, 10- O-lari-oh. Each time you would sa o-Lari, you would bounce the ball under your leg. Does any one know if this is the whole rhyme? Does any one else remember such and activity?
