This file includes activities to practice ordering three objects by length, comparing lengths of objects and measuring objects with length units as stated in CCSS 1.MD.1 and 1.MD.2. Students will use the terms shorter, shortest, longer and longest to compare objects. Unifix/connecting cube pages are provided if needed.
CCSS.Math.Content.1.MD.A.1 Order three objects by length; compare the lengths of two objects indirectly by using a third object.
CCSS.Math.Content.1.MD.A.2 Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.
