This is an introductory lesson for the beginning of first grade. We will begin by emphasizing the relationship between part-part-whole. Since today’s lesson is introductory, we will not focus on subtraction.
- The learner will add and subtract within 20.
- The learner will understand that there are different pairs of numbers that will have the same sum (5 + 0 = 5, 4 + 1 = 5, 3 + 2 = 5).
