Refer to the unit you are currently teaching. Many preschools have a set curriculum that students adhere to in a given time frame. If the school has more than one teacher per grade, all teachers are expected to work on that specific unit during that time.
Title the lesson. The lesson plan should have a title that explains what you hope to accomplish. For example, if you want to help students associate with the vowel "e," the title should specifically reference this fact.
Write down the grade level and subject area. Students may attend pre-kindergarten classes for up to three years until they start kindergarten. A lesson plan that focuses on skills for two-year-olds will be different from a lesson plan that focuses on skills for slightly older children. Preschool teachers help students explore many different subjects, including science, personal care and basic math. Note which subject you intend to address.
Write a detailed lesson description. Cover all the steps that you plan to take during the lesson, such as when you will begin an activity and when it should end. If possible, break down each part of the lesson into five-minute sections.
List all required materials. If you are using watercolors or markers, write this down. Write down which materials are already in the classroom and which materials you may need to pay for or ask parents to bring in.
Note all safety precautions that must be taken. If students are observing the growth of trees on the ground and the varied patterns created by leaves, make sure that the area of observation is free from obstacles a small child might stumble over.
Indicate which items will be created as a result of the lesson plan. If you are telling students how to make a snowman from three balls and assorted buttons and ribbons, describe the expected end product.
