Judith's 4th grade class has a spelling list organized by subject. The spelling list includes 120 words about history, 115 words about science, 70 words about math, and 45 words about geography. Each week, Judith's teacher tests her on 15 words from the list. Judith's class has already had 6 weeks of spelling tests. How many more words will Judith be tested on before the end of the year?

Step 1: Focus on the relevant information only.

Spelling list by subject and number of words:

History = 120
Science = 115
Math = 70
Geography = 45
TOTAL = 350

We know that:
each week = 15 words tested
Tests already taken = 6

So: 15 * 6 = 90

Now, we need to find the number of remaining words still left on the list:

TOTAL WORDS: 350
(Minus) words already taken: 90

350 - 90 = 260

So there are 260 words yet to be tested before the end of the year.
