This two-week unit develops student knowledge, understanding and skills of what you want to describe decides the unit of measure you use. Students are provided opportunities to:
compare, describe, and understand the world around us when measuring
think about how much longer, shorter, or the same something is in comparison to something else
experiment with object’s length in different positions or locations
tell time on analog and digital clocks
explain their thinking so it makes sense to others.
Before engaging in these teaching and learning activities, students would benefit from prior experience with:
opportunities to demonstrate an increasing understanding of measurement and number using vocabulary to describe size, length, and names of numbers
noticing and predicting the patterns of regular routines and the passing of time
discussions contributing constructively to mathematical discussions and arguments about symbol systems, for example, letters, numbers, and time
use language to communicate thinking about quantities to describe features of objects and collections, and to explain mathematical ideas.
