W-well, you take the blocks from this basket and slide them into place. Each basket has the same amount of blocks, and every group of blocks in the basket has a word, number, or symbol etched onto its outer surface. B-by sliding the right blocks into place you can take measurements and record information. When you've finished with sliding everything into place, you take the right edge of the board and slide it down to close the rows and keep the blocks from falling out. I-if you want to clear the board, just slide it back up and put the blocks back into their proper places inside the basket.
