Problem-Solving Strategies
Let’s explore some effective strategies for tackling SAT math problems:
Understand the Problem
Read the question carefully.
Identify what is being asked and the information given.
Plan Your Approach
Decide on the best method to solve the problem (e.g., algebraic manipulation, drawing diagrams, or using logical reasoning).
Write down key equations or steps.
Solve Step-by-Step
Work through the problem methodically.
Check your calculations and ensure all steps are clear and logical.
Review Your Answer
Verify that your answer makes sense in the context of the problem.
Check for any mistakes or missed details.
Practice Activity: Solving Sample Problems
Let’s apply these strategies with some sample SAT math questions. Follow these steps:
Read the Problem Carefully: Understand what is being asked.
Choose a Strategy: Decide on the best method to solve the problem.
Solve Step-by-Step: Work through the problem and show all your steps.
Sample Problem 1:
Question:A triangle has angles in the ratio 3:4:5. What are the measures of the angles?
Options:
a) 30°, 40°, 50°
b) 45°, 60°, 75°
c) 36°, 48°, 96°
d) 36°, 54°, 90°
Solution Steps:
Let the angles be 3x3x3x, 4x4x4x, and 5x5x5x.
The sum of angles in a triangle is 180∘180^\circ180∘: 3x+4x+5x=1803x + 4x + 5x = 1803x+4x+5x=180
Solve for xxx: 12x=180 ⟹ x=1512x = 180 \implies x = 1512x=180⟹x=15
Calculate the angles: 3x=45∘,4x=60∘,5x=75∘3x = 45^\circ, \quad 4x = 60^\circ, \quad 5x = 75^\circ3x=45∘,4x=60∘,5x=75∘
Answer: b) 45°, 60°, 75°
Sample Problem 2:
Question:A rectangular prism has a volume of 216 cubic centimeters. If its length is 6 cm and its width is 9 cm, what is the height of the prism?
Options:
a) 3 cm
b) 4 cm
c) 5 cm
d) 6 cm
Solution Steps:
Use the volume formula for a rectangular prism: V=l×w×hV = l \times w \times hV=l×w×h.
Substitute the known values: 216=6×9×h216 = 6 \times 9 \times h216=6×9×h
Solve for hhh: 54h=216 ⟹ h=21654=454h = 216 \implies h = \frac{216}{54} = 454h=216⟹h=54216=4
Answer: b) 4 cm
Vocabulary in Context
Understanding key math vocabulary is crucial. Let’s discuss some terms from the problems:
Ratio (noun): A relationship between two numbers indicating how many times one value contains or is contained within the other.
Volume (noun): The amount of space occupied by a three-dimensional object, measured in cubic units.
Prism (noun): A solid geometric figure with two identical ends and flat sides.
Activity: Use each term in a sentence related to the problems.

Warm-Up Activity
Start with a quick reading exercise. Read the following short passage and write a brief summary:
Passage:"In recent decades, the debate over the impact of technology on society has intensified. While some argue that technology has improved quality of life by increasing efficiency and connectivity, others contend that it has led to a decline in social skills and mental health. The rise of social media and digital communication has changed how people interact, often reducing face-to-face interactions and increasing feelings of isolation. As technology continues to evolve, it is essential to consider both its benefits and drawbacks to find a balanced approach that enhances human well-being."
Your Task:
Write a summary of the main points in one paragraph.
Advanced Reading Comprehension Strategies
To excel in the reading section, you need to master these advanced strategies:
Critical Reading
Analyze the Author’s Argument: Look for the thesis, evidence, and reasoning. Evaluate the strength and relevance of the arguments presented.
Understand the Context: Consider the historical, cultural, or social context of the passage. This can provide deeper insight into the author’s perspective
and purpose.
Identify Key Details
Main Ideas vs. Supporting Details: Distinguish between the central arguments and the supporting evidence or examples.
Highlight Key Points: Mark important sentences and phrases that summarize the main ideas or provide crucial evidence.
Infer Meaning
Context Clues: Use the surrounding text to infer the meaning of unfamiliar words or phrases.
Read Between the Lines: Look for implied meanings and unstated assumptions.
Synthesize Information
Connect Ideas: Relate information from different parts of the passage to form a comprehensive understanding.
Summarize and Paraphrase: Practice summarizing paragraphs in your own words to reinforce understanding.
Practice Activity: Analyzing a Complex Passage
Let’s apply these strategies to a sample reading passage. Follow these steps:
Read the Passage Carefully: Take your time to understand the text.
Identify the Main Idea: What is the author’s primary argument?
Highlight Key Details: Mark important points and evidence.
Infer and Synthesize: Make connections and draw conclusions from the text.
Sample Passage:
"The rapid advancement of artificial intelligence (AI) is reshaping industries and societies around the globe. Proponents argue that AI has the potential to revolutionize healthcare, education, and transportation, leading to unprecedented efficiency and innovation. However, critics warn of the potential risks, including job displacement, ethical concerns, and the exacerbation of social inequalities. As AI technology continues to evolve, it is crucial to develop robust policies and regulations that ensure its benefits are widely shared and its risks mitigated."
Your Task:
Identify the main argument of the passage.
List two key details that support the argument.
Infer one potential unstated concern about AI that the author might have.
