资源简介：
When a scale is equal on both sides, it balances out. The creation of the scale was to show how two parts of an equation (addends) equal the whole number. When the two parts are equal to the whole number. The scale balances out. This shows that both sides are equal to one another. The user of the manipulative is to learn that both addition and subtraction equations can be used to show situations involving a missing part.
