Teach the children the basic concepts of biological symmetry. Answer questions and ask the children whether they can think of other animals that are symmetric. Ask them questions about what butterflies look like. After the children ponder the topic, ask them to consider what they can write about regarding symmetry and butterflies.
Ask the students whether nature is ever truly symmetric. Even though a butterfly's wings are similar, they may be slightly asymmetric. Ask the children to write about this.
Discuss butterfly anatomy, talking about how the butterfly has a head, thorax and abdomen, with two large wings. When possible, show the children an enlarged picture of the butterfly’s head to show that even the head is almost symmetric.
Teach children the terminology used to describe butterflies, including the forewing, hindwing, abdomen, legs, proboscis, antennae and head. Encourage the students to use these words in their writing.
Make sure all the children have tools necessary to write, including paper and pencils. Carry extra erasers and paper for children who forget to bring their own.
Let the children know what they are writing about and why they are writing it.
Find a way to let the children read their papers for an audience. Children are more interested in writing and improving their writing quality when they know that they are writing for an audience. The students should also share their writing when they want to, even before they are finished.
Include all the resources the children need to write about the topic, including biology books, pictures of butterflies or even a live butterfly. Images help children visualize what they will write about.
Give the children time to write. Do not put heavy pressure on children who struggle, since frustration can discourage them from writing. Be available to help children express their ideas, so they do not become frustrated and discouraged.
Encourage students to look over what they have written to find any misspellings or grammatical errors. Only emphasize grammar concepts that were covered in class, such as basic punctuation rules.
Evaluate the essays. Focus on whether they understand the concept of symmetry and whether they apply the grammar and spelling lessons learned in class.
