Adding 2-3 Digit Numbers Using Base 10 Blocks

This video tutorial teaches how to add 2-3 digit numbers using base 10 blocks. It explains the concept of place value, where each digit's value depends on its position in the number. The tutorial demonstrates the use of base 10 blocks, where cubes represent ones, longs represent tens, and flats represent hundreds. Two examples are provided: adding 341 and 156, and adding 123 and 235, both using base 10 blocks to visualize the process. The video emphasizes that the order of numbers in addition does not affect the result.
