My question is about the example in the top right column, Write 32/5 as a mixed number.
This is a 4th grade math book. Should there be a space between the r and the shaded square following it. Otherwise it looks like the word red. Or would it be better with no space and a dot 5, since the square represents a number? Thank youIn work arranged spatially, only the general omission symbol (full cell) is used to show omissions. NC Sec.58.
Do not use a shape symbol for a shaded square in a spatial arrangement.
The general omission symbol is not a numeric symbol, even if it is representing a missing numeral, so there is no need for a dot 5 between the r and the full cell.One more question about shaded squares. I have a number line with fractions above and the decimal equivalent underneath. After 0.2 there are shaded squares for the next seven positions, followed by 1.0 for 10/10. Since number lines are considered a graphic illustration, I use the omission symbol for these shaded squares also, correct?
The rule (NC Sec.48) actually applies to work arranged spatially for *computation, not to graphics, but I see no reason not to use the general omission symbol here.
