This document outlines a proposed 6-week math unit for a 3rd grade class. The central idea is that numbers are used to describe, compare, and measure quantities. Key concepts are function, connection, and change. Lines of inquiry include place value systems, fractions and decimals as representations of whole-part relationships, and number operations. Assessment tasks will evaluate student understanding of place value, addition/subtraction, fractions/decimals, and long division. Learning experiences include exploring counting strategies, discussing differences between strategies, representing number relationships, and creating mind maps. The unit aims to develop self-management skills and principled, balanced attributes through math inquiries.
