SORTING, COMPARING, AND ORDERING FIRST GRADE UNIT FOUR

STANDARDS MCC.1.MD.1 Order three objects by length; compare the lengths of two objects indirectly by using a third object. MCC.1.MD.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. MCC.1.MD.3 Tell and write time in hours and half-hours using analog and digital clocks. MCC.1.MD.4 Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

MEASUREMENT STANDARDS In the original unit, emphasis was on nonstandard units of measure After reviewing the measurement and data progressions document and looking vertically at what is taught in Kindergarten and 2 nd grade, tasks were added and changed to focus more on using standard units of measure interchangeably with non-standard units A better picture of this can be seen in the unit overview Measurement Trajectory document (pushed out to you, too!)

FORMATIVE ASSESSMENT LESSON There is a Measurement FAL It has been inserted early in the unit, but its use is up to the discretion of the individual teacher based on the needs of his or her students. 2/3 of the way through the unit is a great place…
