Understanding Base Ten Blocks Concepts

The video tutorial demonstrates how to perform subtraction using base ten blocks and write the result in expanded form. It begins by defining the base ten blocks: flats as ones, longs as tenths, and bits as hundredths. The example used is subtracting two and eighty-three hundredths from four and two-tenths. The process involves exchanging blocks to facilitate subtraction at each place value, starting with hundredths, then tenths, and finally ones. The final result is expressed as one and thirty-seven hundredths, both in standard and expanded form.
