//Assessment Tasks//

|| //**Stage 1 - Symmetry**// This task requires students to create a design using two, three or four pattern blocks. They create a two-dimensional representation of the design by tracing around it on the worksheet, placing one edge of their design on the line of symmetry provided. Students flip their design into the flip design section of the worksheet and trace around it. They describe in writing the shapes they used and what they did to flip the design. ||
