Most children learn to recognize letters between ages 3 and 4. Once you start sharing the letter "O" worksheets with them, your kindergarten students will recognize the letters whenever they see them. As mentioned in the worksheet below, the students will have to color the shape of Orange in order to remember the letter. Later they can identify the letter "O" from the pool of different alphabets. As a teacher, you should make your class fun and engage. So, when you make the worksheet for your students, ensure that they learn something new and have fun while they achieve the desired results.
