I love 10 frames and I love penguins! I use these 10 frames with my preschoolers to practice quantity and number sense. Print all pages on cardstock, laminate for durability and cut out. I lay all penguins face down and let students pick one penguin. They say the number and add goldfish crackers to the 10 frames to correspond. As a nice treat, I let them eat a few goldfish when they have added the correct number of crackers to the 10 frames.
