Write down your ideas for a lesson plan. Start by writing down topics that could make up your lesson plan, such as weather, then breaking the topic down into individual units. Break down weather into seasons, then into the different weather patterns that happen in each season.
Check your state or provincial curriculum to find out what students are supposed to learn about the subject you have chosen. A kindergarten lesson plan will probably simply introduce students to ideas and teach them basic information. In the case of weather, this would be the types of weather that happen in each season, rain and snow coming from clouds, and the sun warming the Earth.
Write out a step-by-step plan on how you will set up the lesson. Using the weather example again, teachers could start by asking the students what the current season is and what weather happens during that season. For an art lesson related to weather, the children could draw what the weather would look like during that season, the plants and animals, and what people would be wearing. A science lesson could be freezing water into ice, then seeing how quickly it thaws at different temperatures.
Write down an evaluation process for the children after the lesson. If you've done an art project on weather, assess the detail in the students' pictures so you get a sense of the depth of their understanding. For a science experiment, evaluate their participation as well as how they predict and explain.
Include a section in your lesson plan that makes connections to other subjects. If the students' responses focus on animals, be prepared to take the lesson in that direction, teaching about animals habits in the weather you're talking about. If they are interested in why certain weather happens, have illustrations available to show quick explanations of the weather.
