I got dd some Hama Beads for christmas as the school have been doing them with her to improve her concentration and fine motor skills.
I am just amazed at how long dd has sat and done them for (probably about half an hour unaided!). Apparently when school first gave them to her she would put about 10 beads on and walk away. Now she will sit and do a whole shape, such as a heart or a star. I also think it helps with her fine motor skills too as she is picking them up very carefully and not dropping any. She also makes patterns with the beads.
Just thought I'd share that with you as I think they are really good Oh yes and ds loved them and I sat and did half of one too (didn't have the concentration to finish it ).
