This math unit begins by strengthening students' understanding of base ten blocks in representing numbers, starting with identifying numbers in pictorial form and translating these into numerical and word forms based on hundreds and tens. As the unit progresses, it shifts focus to teach subtraction using base ten blocks. It starts with simpler tasks that require forming subtraction equations from visual representations (cross-out) without borrowing, involving digits in tens and ones places. Students gradually move towards more complex subtraction problems involving hundreds and eventually thousands, still without the need for borrowing. The unit then introduces exercises that require borrowing within subtraction, thus dealing with more complex numerical concepts involving larger quantities represented by hundreds and thousands. This progression builds a comprehensive understanding of base ten concepts and subtraction, enhancing students' ability to interpret, calculate, and express numerical values visually and numerically.
