Terracotta pots and sorting? Yes. I found these terracotta plant holders (well they aren't really plant holders, they are the dishes that catch the water from the plant but their name escapes me at present) at the local bargain store and picked up a few with gardening in mind. But, they're shallow and small - excellent for sorting!
I decided to do an activity for older toddlers to help them to continue strengthening their sorting skills insha'Allah.
Sorting helps children build important critical thinking skills that will later be used in math and science. It also provides fine motor skill work as well.
This is the game/activity before it is ready to be played. I laminated the pieces that need to be sorted. The pieces are about the size of a quarter and can be easily damaged with frequent handling.
The larger circles have pictures that are identical to the game pieces. Those can be taped into the bottom of the terracotta dishes or if you laminate them, you can simply place them into the bottom of the dish. I think taping them down is good so they don't get lost.
The control of error in the activity is the larger circles that are in the bottom of the dish. They match the game pieces. The child can look into the dish and if one of the pieces/coins does not match the picture in the bottom of the dish, he/she can self-correct insha'Allah. You can read more about control of error in Montessori education here insha'Allah.
I intentionally placed pictures in the dishes that are very dissimilar. This will help the child visually discriminate between the two pictures that he/she needs to sort insha'Allah.
