You can do many activities to tie your apple theme to the subject of language arts. Discuss the fact that the word "apple" starts with the letter A, then have children color and trace the letter A and the word "apple." Read books about apples or about Johnny Appleseed, and have children listen for different types or features of apples. Help children learn to recite songs or poems about apples or apple picking.
Have each child bring in a favorite type of apple from home. Make a graph showing the color of each child's favorite apple and discuss how many students like each particular color of apple. Alternatively, have students sample small pieces of red, yellow and green apples and choose a favorite. Graph the results of this taste test. Cut apart apples and have the children count how many seeds are in an apple.
Discuss how apples grow and what things apples need in order to grow. Talk about how apples grow on trees from seeds and discuss other things that grow from seeds, such as beans. Remind children that an apple is a fruit, and discuss other types of healthy fruits. Remind them that it is important to eat fruit every day to be healthy and suggest fun ways to eat apples, such as with peanut butter.
As an art project, cut an apple horizontally instead of vertically. Look at the star shape in the middle. Pat the apple dry and paint the center to use as a stamp. Staple a brown trunk to a paper plate and have children use yellow, red and green paint to make fingerprint apples in their tree. Sing songs related to apples such as "Ten Little Apples," to the tune of "Ten Little Indians."
