In this lesson, first-grade students will go through the foundational concepts of addition and subtraction. Discuss how addition means "putting together" and subtraction means "taking away." The central focus is to introduce students to basic addition and subtraction operations within 20. Students will learn to solve simple addition and subtraction problems using concrete objects, drawings, and equations with unknown numbers. The lesson aims to foster a conceptual understanding of addition and subtraction as combining and separating quantities. Through guided and independent practice, students will strengthen their understanding of addition and subtraction concepts while meeting the standards for representing and solving problems within their grade level.What knowledge and skills would need to be taught before this lesson to make sure students are able to retain the content?
