I got her a stationary organiser and it was a good choice as she used to put all her writing material in a box. After a while, searching for her pencil, eraser or scissors became impossible as they were all in a mess in that box. Now it is much neater and C doesn't need to dig in as everything is in sight.
We also bought a Post-It board where she can paste important notices. The old CD player was faulty hence Daddy got her this cute little CD player because I play music when C is doing her work.
