This is a fun book that covers standardized units of measuring in centimeters (cm), inches (in), feet (ft), and yards (yd). This book was created to accompany The Story of Ferdinand by Munro Leaf. Just as Ferdinand's growth was recorded on the tree, students will use the first two pages of their book to write their own growth measurements (in inches as well as feet and inches) and color their marks on the growth chart tree. There's a Color by Unit of Measure page as well as two pages for measuring and recording various object in cm, in, ft, and yards. This booklet is listed for grades 1-4, but it includes measurement in centimeters, inches, feet, and yards - so PLEASE check all images to ensure this booklet will work for your students.
