Pre-K friends learned about the WEIGHT. Some things are heavy, somethings are light. To explore the weight we used a scale. We discovered that heavy things pull the scale dish down, bringing light objects up. As you see Nosson is trying to match weight of an apple with number of beads. An apple is heavier than an amount of beads, that is why its dish down. As soon as Nosson found the match to the apple weight, the dishes were about the same height.
People have weight too. Friends guess their weight, then check their estimates using a scale.
Friends noticed that scale gradation starts with the number 0.
