This Writing Instructional Intervention Supplement from the Mississippi Department of Education contains benchmarks, informal assessments, and suggested teaching strategies for the fourth through eighth grades. Benchmarks outline what students should know and be able to do to meet mandated competencies. Informal and observational assessments determine if benchmarks are being met. Instructional intervention strategies assist a child in meeting a benchmark. In addition, a description of sentence patterns, a Sample Writing Assessment Rubric, and a 42-item glossary of technology terms are included. A list of online resources provides 38 Web sites relating to the following: search tools; search engines especially for kids; language arts sites; current events/ news; activity-based sites; teacher resources; and reference sites.
