Design signs and visual aids showing the letter "A." Write the upper- and lower-case versions of the letter in large, colorful letters accompanied by illustrations of words that begin with the letter, such as apples and airplanes. Hang these signs in every area of the room at the preschoolers' eye level. Wherever they play in the classroom, they'll be able to see these signs.
Make small cards and other portable signs demonstrating the letter. You may use smaller versions of your posters, or create cards that show only an upper- and lower-case letter "A." Laminate these cards to protect them. You may tape one card to each student's spot at the table. You may also hold these signs up at circle time or pass them around for each child to study up close.
Create worksheets. When preschoolers are just learning about the letter "A," focus on teaching them to identify the letter. Black out the word bank on a word search sheet. When you pass these sheets out to students, ask them to circle all the letter "A's" rather than trying to find words. Once students are familiar with the letter, make tracing sheets by writing "A" in dotted lines on writing paper so preschoolers can practice writing the letter.
Stock the classroom with books featuring the letter "A." Borrow library books about the alphabet or look for books about apples, animals or characters whose names start with "A." Read one book every day of your lesson plan.
Plan some games and activities that will make preschoolers excited about the letter "A." You may take them on a hunt around the school to find items whose names start with "A," make alligator or ant puppets or hold an "A" party and serve animal crackers, angel food cake and apple juice.
