This math topic involves using base 10 blocks and subtraction techniques to solve problems. Students will view pictures where they must count and cross out blocks to find the remaining ones, focusing on the hundreds and tens place, without needing to borrow. The problems are designed for students to practice subtraction of 1 and 2-digit integers using visual aids. Each question presents a different setup but follows the same principle of identifying how many blocks are left after subtracting, helping to enhance counting and subtraction skills.
