FAQ
How do students determine the multiplier needed to find a missing numerator or denominator?⌄
Students look at the relationship between the two denominators (or numerators) to find the scale factor, then apply the same multiplication to the other part of the fraction to find the missing value.
What happens if students divide instead of multiply to find the missing number?⌄
Dividing is equally valid — if the second denominator is smaller than the first, students divide to find an equivalent fraction in lower terms, making this a reversible procedure.
How do missing-number equivalent fraction problems connect to algebra?⌄
These problems are fraction-based proportion equations (a/b = ?/d), directly previewing the cross-multiplication strategy students will use to solve proportions in 6th and 7th grade.
