Balancing Scales and Weights

The video tutorial explains how to determine the weight of each item on a balanced scale. It starts by describing the concept of a balanced scale, where both sides weigh the same. The right side has a total weight of 35, and the left side has seven unknown weights. The tutorial uses counters and visual aids to solve the problem, demonstrating that each weight must be 5 to balance the scale. The process involves using multiplication and times tables to verify the solution.

What does it mean when a scale is balanced?

• The left side is heavier than the right side.

• Both sides weigh the same.

• The right side is heavier than the left side.

• The scale is broken.

If the right side of a balanced scale weighs 35, what must the total weight on the left side be?

• Exactly 35

• More than 35

• Less than 35

• It doesn't matter

What method is used to solve the problem of finding the weight of each item on the left side?

• Using a calculator

• Guessing the weight

• Weighing each item individually

• Using counters or circles to represent groups

What multiplication fact helps solve the problem of finding the weight of each item?

• 7 * 3 = 21

• 7 * 6 = 42

• 7 * 5 = 35

• 7 * 4 = 28

What is the weight of each item on the left side to balance the scale?

• 4

• 6

• 5

• 7
