Here is a great free Spanish printable for your preschooler. I am doing one letter per week and working with my own preschooler on that particular letter.
Print out your "A" page here with Spanish words that start with "A."
Have your preschooler trace the letter A. Then have him or her decorate the A's. Come up with something creative like help them draw a bunch of Arañas all over the A. Or use glitter glue, pompoms, or stickers of anything that starts with A in Spanish. Have your preschooler color and cut out (supervised of course) the pictures. Paste them into this letter book:
here and here.
