Fractions

Practice 3 items →

A fraction is a number on the line, not a pizza slice that has to be less than one. Students place fractions on a number line, generate equivalents, simplify, convert improper and mixed forms, and compare using common denominators or the benchmarks one half and one.

Students can

place fractions on a number line; generate equivalents; simplify; convert improper ↔ mixed; compare with common denominators or benchmarks $\frac12$ and 1.

Ready when

they can sort $\frac38,\frac12,\frac34,\frac76,1$ on a line and justify two of the comparisons two ways.

Watch for

$\frac35 > \frac34$ because 5 > 4; mixed numbers compared by whole part only.
