Understanding Constants

Mr. Buffington introduces the concept of constants, explaining their role in multiplication and how they are represented in tables. He provides equations to find constants and demonstrates their use through examples and practice problems. The lesson concludes with a word problem to apply the learned concepts, emphasizing the importance of constants in calculations.

What is the role of a constant in a multiplication table?

• It changes with each calculation.

• It remains the same for all calculations.

• It is only used for addition.

• It is used to divide numbers.

How do you find the constant if you have the x and y values?

• Add x and y values.

• Divide y by x.

• Subtract x from y.

• Multiply x and y values.

Why is zero not useful when finding a constant?

• It has no effect on the constant.

• It doubles the constant.

• It results in a constant of zero.

• It makes the constant negative.

In a table with missing values, how do you find a missing y value?

• Subtract the constant from x.

• Multiply the constant by x.

• Divide the constant by x.

• Add the constant to x.

What equation would you use to find a missing x value in a table?

• x = y * k

• x = y / k

• x = y + k

• x = y - k

In the word problem, what is Kaz's rate of shooting arrows per minute?

• 6 arrows per minute

• 5 arrows per minute

• 4 arrows per minute

• 5.5 arrows per minute

How long does it take Kaz to shoot 50 arrows?

• 11 minutes

• 8.5 minutes

• 9.1 minutes

• 10 minutes

What is the relationship between the unit rate and the constant?

• The unit rate is half the constant.

• The unit rate is the same as the constant.

• The unit rate is double the constant.

• They are unrelated.

Which equation is used to calculate x when given y and the constant?

• x = y + k

• x = y - k

• x = y / k

• x = y * k

What is the equation to find y when given x and the constant?

• y = k + x

• y = k * x

• y = k - x

• y = k / x
