Math Problem Solving Strategies

In this video tutorial, the teacher guides students through solving algebraic equations using substitution and error correction. The lesson begins with an introduction to the problem, followed by solving for Y and X. The teacher demonstrates the substitution method and addresses a mistake in calculations, emphasizing the importance of checking work. The session concludes with a reflection on the learning process.

What is the 'We Do' method in learning?

• A method where the teacher solves everything.

• A collaborative approach where students and teacher solve problems together.

• A method where students work independently.

• A method where students only listen to lectures.

What is the first step in solving the equation -3x + y = 11 for y?

• Divide both sides by -3.

• Subtract 3x from both sides.

• Multiply both sides by 3.

• Add 3x to both sides.

After solving for y, what is the next step in the process?

• Solve for x in the same equation.

• Substitute the value of y into the second equation.

• Check the solution immediately.

• Rewrite the second equation without substituting y.

What mistake did Mr. Adams identify in his solution process?

• He multiplied instead of divided.

• He added instead of subtracted.

• He forgot to substitute a variable.

• He copied a negative sign incorrectly.

How can you verify your solution without a teacher's book?

• Ask a friend for the answer.

• Trust your initial answer without checking.

• Use a calculator to check the arithmetic.

• Graph the equations to see if they intersect at the solution.

What is the final solution for the system of equations?

• (5, 2)

• (0, 0)

• (-10, 30)

• (2, 5)

Why is it important to write in pencil during math class?

• To make the work permanent.

• To easily correct mistakes.

• Because it's required by the teacher.

• Because it looks neat.

What should you do if you find a mistake in your test?

• Ask the teacher to correct it.

• Ignore it and move on.

• Leave it as it is.

• Correct it immediately.

What is the benefit of writing out all your work?

• It impresses the teacher.

• It is not beneficial.

• It helps in identifying mistakes.

• It takes less time.

What tool can be used to graph equations and verify solutions?

• A calculator.

• A protractor.

• A ruler.

• Desmos.
