We do memory work as a group. One or more times a day. We run through it sometimes together or sometimes individually. They like to jump while saying each word. Or do it while swinging. The car makes for a nice captive group. Doing it all tougher seems to make it more fun for them. They also like to show off for each other. We do days of week, months,planets,two phone numbers,our address counting by 2s 5s 10s and to 100,and poetry.
