This set is perfect for when you introduce numbers. I would print on cardstock for longevity. There is a number formation poster for numbers to 20. Each number has a number picture that includes different ways to see that number. The image is as large as I could make it on an 8 1/2″ x 11′ size paper. Each number also includes six picture cards with ways to show that number.
Please let me know if you have any questions.
