Lesson Plan Description
In this 2 segment 1 and 1/2 hour math lesson, for Operations & Algebraic Thinking, 1st grade students will relate counting to both addition and subtraction using a number line. In addition to learning how to use a number line by physically moving their own bodies to represent the equations, they will demonstration their understanding of the relationship between addition & subtraction using a color by number activity.
In segment 1, students will practice using a umber line to both add and subtract numbers and begin to see how counting is related to both addition and subtraction. They will also practice couting by 2’s to add 2 to a number.
In segment 2, Students will play a game that will demonstrate their understanding of how counting is related to addition and subtraction.
Each segment has an exit slip that will provide valuable instructional information to you regarding your students understanding of the relationship between addition and subtraction.
