Students will be challenged and motivated while completing the activities included in this packet. First students will create a "Book of Measures". Using self-selected objects, students will measure the length, width, and height of each object. When complete, students will read "Twelve Snails to One Lizard: A Tale of Mischief and Measurement" (Not included). Students will then select an item to use as their standard unit of measurement and measure other objects in the classroom using this selected item. Finally, they will find the measurement (in inches) of the object they used as their standard unit of measurement and estimate the size (in inches) of the previously measured items. Primary friendly rubric is included. Students love this engaging activity that allows them to explore the world around them in a new and creative way!
