Math Grade 1 Quiz three objects by length; compare the lengths of two objects indirectly by using a third object-1.MD.A.1 

This standard introduces students to the concept of measurement by having them order objects based on their length. It emphasizes both direct comparisons (comparing two objects directly) and indirect comparisons (using a third object as a reference to compare the lengths of two objects). Through this, students gain an understanding of relative lengths and begin to develop the foundational skills necessary for more advanced measurement concepts in the future
