Toddlers are sensory learners who love to touch, smell, and taste to understand the world around them. Use a dark marker to trace letters of the alphabet and/or numbers onto poster paper; then have your tot decorate the letters with textured items such as sandpaper, beans, cotton balls, pastas, and pipe cleaners. Touching the letters gives kids the opportunity to feel the way a letter is formed. For little ones learning to write, their fingers can experiment with the shape of a letter before grasping a writing utensil. Each day, say the letters and numbers out loud as your child runs his fingers over them. Later on, extend the activity by creating a poster that spells out his first name. Soon your child will notice these letters on signs, posters, and billboards.
