This math unit progresses from basic addition and subtraction concepts using visual aids and small numbers to tackling more complex arithmetic operations involving larger integers. Students begin by learning to add and subtract without carrying or borrowing using base 10 blocks, including concepts of tens and ones and progressing to hundreds and thousands. They then move to adding two-digit numbers to one-digit numbers and vice versa, enhancing their skills in basic arithmetic operations and integer understanding. Subsequently, the focus shifts to include missing value problems and column addition methods, allowing students to practice the addition of three whole numbers and solving equations with unknowns. The unit advances to include larger problems involving the addition and subtraction of three-digit numbers both in and out of columns, providing further practice in aligning and calculating larger integer values. Overall, this unit thoroughly enhances students' conceptual grasp and computational skills from foundational single-digit operations to more complex multi-digit arithmetic.
