Play-Doh time with our NOTW. We use a cookie cutter to imprint the number talking about how it's a "1" and then do the "1" again! We also make snakes to put on our number one play-doh mats.
My 3 year old practices writing his number of the week. He is getting much better at his fine motor skills putting those 11 stickers into his sticker book and I think the 2 year old is catching on as well.
