Measuring Up: Prototypes for Mathematics Assessment
It is also assumed that the students have had some experience in dealing with newly defined geometric objects. The assessment activity does not, however, assume any familiarity with hexarights. Indeed, part of what is being assessed is children's abilities to grapple with a concept that is new to them.
Presenting the task: The teacher should first be sure that everyone recalls that a hexagon is a 6-sided plane figure, and that adjacent sides are sides that touch. Then he or she should distribute copies of the student sheet and read through the first item to ensure that everyone has a beginning understanding of what a hexaright is. As always, tools for drawing should be available for children to use as they see the need. The tools should include rulers, L-squares (which provide an easy way to draw right angles), centimeter tiles, and centimeter graph paper. An L-square is provided on the back cover of this book.
Student assessment activity: See the following pages. Note: the student work pages have been drawn to fit the 7'' × 10" page of this volume. Reproduction of these pages for student use may affect the scale of the centimeter graph paper in questions 2 and 3 and the hexaright in question 4. The teacher may choose to redraw these diagrams to achieve proper scale.
