I recently introduced this animal matching activity (that I made for O about 3 years ago) to E(1), and she really liked it.
To make this activity, I bought 2 mini animal calendars and cut them apart. I added labels and laminated the cards. I put 3 to 5 cards out at a time, and then hand E one card at a time to match. She loves animals, so this is a fun activity for her.
