ühikvõre

ühikvõre is an Estonian term that translates to "unit lattice" or "unit grid." It refers to a visual representation used in mathematics and education to demonstrate and understand concepts related to whole numbers, fractions, and decimals. Typically, a ühikvõre is a square grid made up of 100 smaller squares, where each small square represents one-hundredth of the total area. The entire 10x10 grid is considered one whole unit.

This visual tool is particularly useful for illustrating the relationship between fractions and decimals. For instance, shading 30 of the small squares can represent the fraction 30/100, which is equivalent to the decimal 0.30 or 0.3. The ühikvõre allows learners to see how these different numerical representations correspond to the same portion of a whole.

Beyond basic fractions and decimals, the ühikvõre can be used to explore concepts such as percentages, where the entire grid represents 100%. Operations involving addition and subtraction of fractions and decimals can also be visualized by shading or removing parts of the grid. Its simplicity and clear visual nature make it a valuable pedagogical aid for introducing fundamental arithmetic concepts.
