Counting 1 to 10 Worksheet | Counting and Matching Activity | Counting PracticePrintable numbers 1-10, counting and matching practice for toddlers. Learning numbers 1 to 10 is fun with this preschool activity. Use these Montessori materials to increase interaction with children in home learning. I recommend laminating pages for multiple uses. What you'll need: printer, laminator, scissors, and Velcro dots (hook and loop dots).
