Sundar (Udavi school STEM land coordinator) gave a demonstration on learning Algebra using weighing scale. He used few sketch pens and weighing cubes (1gm) . For example one side had 10 grams and the other side had 5 sketch pens when both were weighing equal. He asked us to find the weight of each sketch pen. Then we discussed and solved few such examples in solveme and came up with all possible algebraic equations.
