Learning is a process of effort by an individual to obtain a whole new behavior change, as a result of the experience of the individual itself in his interactions with the environment. Teaching aids are learning media that contain or carry the characteristics or concepts learned. Or can also be said props are tools that can be absorbed by the eyes and ears with the aim of helping the learning process of children to be more effective and efficient.
Like some media below the balancing scale worksheet:
Number scales are only used for numbers with small values. The arms of the scales on the left and the right must be balanced, and the weight of each child is the same scale. Example of a scale in numbers 3 and 5 on the left arm. To show the results of the sum, you can try hanging a scale from the right arm until the two arms are balanced. It turns out that after the scales are hung at number 8 on the right arm, the scales will be balanced. So the conclusion is 3 + 5 = 8.
