Write & Identify a Real World Algebraic Expression | 6.EE.B.6

The video tutorial guides students through identifying an algebraic expression to represent a real-world situation involving a box and marbles. The box has a mass of 50 grams, and each marble adds 3 grams. The variable N represents the number of marbles. The tutorial explains how to construct the expression 50 + 3N to find the total mass. Students are encouraged to pause and solve the problem before the solution is revealed. The video concludes with a review of the correct expression and an invitation to continue learning math.

What is the initial mass of the box before adding any marbles?

• 30 grams

• 40 grams

• 50 grams

• 60 grams

If each marble weighs 3 grams, what does the variable N represent in this context?

• The number of marbles

• The weight of one marble

• The weight of the box and marbles combined

• The total weight of the box

How do you calculate the total weight of the marbles in the box?

• Subtract 3 from the number of marbles

• Multiply the number of marbles by 3

• Add 3 to the number of marbles

• Multiply the number of marbles by 50

What is the algebraic expression for the total mass of the box and marbles?

• 3 + 50N

• 50N + 3

• N + 50

• 50 + 3N

Which answer choice correctly represents the total mass of the box and marbles?

• C: N + 3

• D: 50 + 3N

• A: 3N + 50

• B: 50N + 3
