Numbers and Base-Ten Blocks (Part 2)

The video tutorial explains how to represent the number 235 using base-ten blocks. It starts by breaking down the number into its place values: ones, tens, and hundreds. The tutorial demonstrates how to use individual units, rods, and flats to represent these values. It then calculates the total number of units in 235 by adding the units from each place value. An alternative representation is also shown by converting flats into rods, maintaining the same total. The lesson concludes with a summary of representing multi-digit numbers using base-ten blocks.
