In & Out works are favorites in our house.  L quickly mastered the most recent one I put together, with the coffee stirrers in the colander, so I decided to make one that is a little more challenging.  I got a set of pipe cleaners and a parmesan cheese shaker from the dollar store and put them in a basket so it was easy to carry without spilling.  I showed L to take the cheese shaker out and set it upright on the table, then put each pipe cleaner in a hole.  This is a little more difficult to control, as the pipe cleaners bend and do not stay rigid like the coffee stirrers do.  Setting up this variation on the same in and out concept refreshed the work for L, and it’s now something she chooses multiple times a day.
