How do we Shade some of the grids to show that 2 ones is the same as 20 tenths?

To show that 2 ones is the same as 20 tenths, you can shade two grids, each divided into ten equal parts, representing the ones. Shade all ten parts in the first grid and all ten parts in the second grid to illustrate that they collectively equal 20 tenths. This visual representation clearly demonstrates that 2 ones (2 shaded grids) is equivalent to 20 tenths (20 shaded parts).
