"Multi-scale" is a focused authoring tool that allows for the representation of dynamically scaled expressions with different weights and at different levels using either integer, decimal or fractional numbers. 15 micro-experiments were developed with the 'Multi-scale' template, focusing on investigating equivalence relationships in integers and expressions and solving problems using variables.
