Appendix
The Common Core Standard that my curricular unit aligns to is:
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.
My curricular unit aligns to this standard as my students will be using different manipulatives to measure bigger objects. My students will be using square tiles and rulers to measure different classroom objects appropriately. Beyond this, when we are gardening my students will be using square tiles, plastic pentominoes, and graph paper to design our garden and walkways. Students will need to be able to measure without gaps and overlaps in order for these garden features to be correct. They will also need to express the length of the gardens and walkways in terms of whole number units related to the manipulatives we have used to create them.
