Properties of Addition - Part 2 - Lesson for Grade 1, Chapter - Addition and Subtraction - less than 20
In "Properties of Addition - Part 2," first-grade students will deepen their understanding of addition within the "Foundations in Operations Within 100" unit, specifically focusing on addition and subtraction of numbers less than 20. This lesson is designed to introduce and practice two fundamental properties of addition: the Identity Property and the Associative Property.
Understanding the Identity Property of Addition, which states that any number plus zero equals the number itself, is crucial for students. Through the "Space Addition: Identity Property Practice Worksheet," students will learn that adding zero to any number does not change the value, reinforcing the concept of addition as an increase in quantity. This foundational knowledge is essential for developing numerical fluency and confidence.
Similarly, the Associative Property of Addition, teaching that the way numbers are grouped in an addition problem does not change the sum, will be explored. Activities like the "Bee Addition: Associative Property Practice Worksheet" allow students to practice this concept through engaging, themed problems. Grasping the Associative Property helps students understand addition's flexibility, encouraging mental math strategies and problem-solving skills.
