PRACTICE BLOCKS
INSTRUCTIONS: Read these instructions to yourself as the examiner
reads them aloud.
This is the practice page for the BLOCKS test. Here is a pile of blocks, all
the same size and shape. On five of the blocks, you will see X's. When the
examiner says GO, but not before, you are to find out how many blocks touch
each block that has an X on it, and then place that number to the right of the X.
For example, the lowest block which has an X on it touches four other blocks.
Please locate them now and place a 4 to the right of the X. Put it there now,
and you may have twenty seconds in which to place the correct numbers to the
right of the other X's.
