For a while, I have been thinking that my daughter was ready for 100 piece puzzles. Tuesday during quiet time, she sequestered herself with a round 100 piece puzzle of a seder plate. I came up later to find her making patters with the pieces and some wooden tiles. She had given up making it by herself, but with minor assistance, she and I whipped through the puzzle. I think the unfamiliarity with the round shape as well as the smaller size of the pieces initially stumped her. Now that she has made this one, I think she will be able to make it independently again and move on to other 100 piece puzzles.
