SMP 4: Model with mathematics Students – create a model to demonstrate their solution. SMP 6: Attend to precision Students use – correct mathematical vocabulary when sharing their thinking. Supporting Information Students Struggling with Concept: Provide more opportunities for the students to find perimeter using a piece of string and then measuring the length of the string. Interventions/Enrichments Use a measuring tape to wrap around the model to find the exact perimeter. Special Education/Struggling Use a pipe-cleaner rather than string because it is more rigid and easier for students to manipulate. Learners ELL Students Excelling with Concept: Gifted and Talented Have students create composite figures on geoboards, dot paper, and/or graph paper and find the area of these shapes. Provide examples of objects that contain half-units (i.e. length is and width is and have 8.5” 4.5”) students find the perimeter. Models to be measured: Sample models may include: geoboards, index cards, small boxes, geometric wooden blocks, sticky notes, or any other rectangular object. Avoid complex shapes and/or circles as well as objects that do not have whole-number side lengths. String Materials Rulers and Yardsticks Dot paper and graph paper (as needed) Tape measure and pipe-cleaner (as needed)
