Want your preschoolers to work on shape identification? We found this adorable "Ship Shapes" file folder game at Preschool Printables {via Muck Monsters}. Students are sure to strengthen visual discrimination, along with shape recognition, as they attempt to match the playing pieces - each piece features a ship with four sails and four different shapes.
Create a file folder game, as intended, so that students can complete the activity on their own or use the playing cards to create an interactive poster/bulletin board and place in your math center. You might also consider creating ship "playing cards" that students can use to test their memory and matching skills with a game of concentration.
