LR Question 1 Explanation

QUESTION TEXT: The graphical illustrations mathematics teachers use enable…

QUESTION TYPE: Most Strongly Supported – Exception

FACTS:

1. Geometric illustrations help students learn geometry by making it more intuitive.
2. This makes it easier for them to calculate by manipulating symbols.
3. Algebra could be made easier with illustrations, too.
4. This is true even though the deepest mathematical understanding is abstract.

ANALYSIS: On these questions it’s best to narrow it down to 2-3 answer choices and then refer back to the stimulus to disprove the more difficult wrong answers. Every wrong answer will always be disproved by a specific part of the stimulus.

___________

1. The final stage of mathematical understanding is abstract.
2. CORRECT. The stimulus doesn’t support this. It doesn’t mention any people who can manipulate symbols but don’t understand math. 
3. True. Illustrations help make geometry intuitive.
4. The stimulus said that “teachers use” illustrations for geometry. This implies that the practice is widespread.
5. Symbols could be effectively used in each case.
