By fourth grade the words getting in a student’s way are long ones, and the long ones are almost all built from Greek and Latin parts. Learning fifteen of those parts unlocks a startling number of words, which is why this shows up in the curriculum right at the point where texts get harder.
The roots repeat across the list
The sheet is built so each root appears in several words:
- tele (far)
TELEPHONE,TELEGRAPH,TELESCOPE,TELEVISION - graph / phon (write, sound)
PHOTOGRAPH,AUTOGRAPH,PHONICS,MICROPHONE - micro / scope (small, look)
MICROSCOPE,MICROPHONE,TELESCOPE - bio / geo (life, earth)
BIOLOGY,BIOGRAPHY,GEOLOGY,GEOGRAPHY,GEOMETRY - therm (heat)
THERMOMETER,THERMAL - chron (time)
CHRONIC,SYNCHRONIZE - auto (self)
AUTOMATIC,AUTOGRAPH - audi / vis (hear, see)
AUDIBLE,AUDIENCE,AUDIO,VISIBLE,VISION - port (carry)
PORTABLE,TRANSPORT,EXPORT,IMPORT - dict (say)
DICTATE,PREDICT,VERDICT - man / scrib (hand, write)
MANUAL,MANUSCRIPT,SCRIBE,DESCRIBE,SCRIPTURE
TELESCOPE sits in two of those groups at once, which is the best word on the
sheet: far plus look. Say it that way and a student never forgets it.
The question that does the work
After the search, put four words on the board and ask what they share:
telephone, telegraph, telescope, television
Someone gets tele. Then ask what all four have to do with, and someone gets
distance. Sound from far away, writing from far away, looking far away, seeing
far away.
That is two minutes, and afterwards students have a tool instead of four
memorized words. The same routine works for port, which gives carry: portable
is carryable, transport carries across, export carries out, import carries in.
Guessing is allowed and should be
Once students have three or four roots, give them a word that is not on the sheet and ask them to guess.
Chronometer. Time plus measure. A student who has met CHRONIC and
THERMOMETER can get there, and getting there without being told is the entire
skill this standard is asking for.
They will also guess wrong sometimes, which is worth allowing. The strategy is strong, not perfect, and a student who knows to check is better off than one who trusts it blindly.
Which grid size
The 14x14, and it is not really a choice. THERMOMETER and SYNCHRONIZE are
eleven letters, MANUSCRIPT and CENTIMETER are ten. The smaller grids cannot
hold enough of these for any root to appear twice, and repetition is the whole
mechanism.
