The Karen Katz book, Daddy Hugs, has been a favorite of Ella's for a long time. It tells about ways a dad shows a child love, using numbers (like 10 "I Love Yous"). Before we read the story, I spread out foam numbers around the room on the floor. As we read the story, we would act out what the daddy in the story did (pat pats, hugs, dancing on Daddy's feet, etc), then E would go grab the number from the floor.
It was a fun way of showing love and working on number recognition. This is a good activity for even those kids with a little less number recognition experience than E because they can see the number on the page then go find the number, making it more of a matching activity. At any rate, I would suggest this book (and most Karen Katz books) for a fun activity!
