Using index cards to play build-a-word card games, writing holiday place cards and writing an animal folk tale are suggestions made by Education.com for first grade writing activities. Writing sight words is another option, along with creating or filling in toy birth certificate information.
Writing an original story, answering a question, creating a family memory book, or writing cards and letters are activities Scholastic suggests for first graders. Teachers and parents can ask questions and have students write down the answers. From these answers, more questions are available and further discussion may open more writing options.
If common core concepts are part of the educational curriculum, worksheets using prompts are also an option. First grade teachers and parents can locate these worksheets for free on sites like K12 Reader.
