If you're tight on time, this is a cinch to prepare. It took me less than five minutes! All I did was take one of Eden's fave nursery rhymes, Incy Wincy Spider, and break it down into four 'events'; Incy Wincy climbs the water spout, gets rained out, the sun dries him off, and then Incy Wincy climbs the spout again. Draw simple illustrations of each scene onto cardboard, cut into cards, and presto! You're done!
Your child's task is to put the pictures into sequence. To make it simpler, you could begin with only two scenes; or, you could sing the song with your tot as you help them put the scenes on order. To add a bit of difficulty, you could add more scenes; or, you could choose a longer/more difficult nursery rhyme; or, you could have two rhymes (2-4 scenes each) and mix up the pieces so that your child has to sort the cards by song, and then by sequence. I put the pieces into a ziplock bag, and take it with us when we're out and about.
