This math center practices both standard and non-standard measurement, depending on the needs of your students. You choose the measuring tool, whether it be one of the 3 included rulers or a tool of your own. Your students then find the winners of the pet show by measuring the various adorable animals to find the tallest, shortest, and longest animals. This center activity aligns with the Common Core Curriculum for Measurement and Data in grades K, 1, and 2.
