The document provides a detailed lesson plan for a mathematics lesson on addition and subtraction of whole numbers up to 100 including money. The lesson plan aims to teach students to solve word problems involving subtraction, analyze word problems by identifying what is asked, and understand the value of sharing. The lesson involves reviewing subtraction facts, working through sample word problems in small groups to identify what each problem asks, and an individual student assessment to reinforce the objective of identifying what is asked in a word problem.
