Understanding Base 10 Blocks

The video tutorial introduces a base 10 block strategy called trading and adding. It explains how base 10 blocks represent numbers, with cubes representing ones and longs representing tens. The strategy involves trading ten cubes for one long to simplify addition problems. The video demonstrates this strategy through several worksheet problems, showing how to combine cubes to form tens and solve addition problems more easily. The tutorial concludes with a recap of the strategy and encourages viewers to like and subscribe.
