3. Operating Instructions
The Math Monster Scale is designed to teach basic math through hands-on play. Each larger monster weight represents its corresponding number, and each small red monster weight represents '1' unit. The set includes 9 larger monster weights and 11 smaller, soft monster weights. This allows your child to take on various logical thinking challenges and learn fundamental arithmetic like addition and subtraction.
Basic Balancing:
- Place the monster scale on a flat, stable surface.
- Select a large numbered monster weight (e.g., the '6' monster) and place it on one of the scale's arms. Observe how the arm goes down.
- To balance the scale, place smaller '1' unit weights or other numbered monster weights on the opposite arm until both arms are level. The arrow near the monster's eye will point to the middle when balanced.
- Experiment with different combinations to achieve balance. For example, a '6' monster on one side can be balanced by six '1' unit monsters on the other.

Learning Addition and Subtraction:
- Addition: Place two smaller numbered monsters (e.g., '2' and '3') on one arm. Ask the child to find a single monster that will balance them on the other arm (the '5' monster).
- Subtraction: Place a larger monster (e.g., '10') on one arm. Place a smaller monster (e.g., '4') on the other. Ask the child to determine how many '1' unit monsters are needed to balance the scale (six '1' unit monsters).
- The included instruction manual provides various game examples and challenges across three difficulty levels to guide learning.
