Virginia SOL 2.NS.3.e.iii
The Standard
set models (e.g., chips, counters, cubes).
Virginia Standards of Learning for Mathematics · The student will use mathematical reasoning and justification to solve contextual problems that involve partitioning models into equal-sized parts (halves, fourths, eighths, thirds, and sixths).

What This Standard Means
What Students Need to Do
- Students split a collection of objects into two, three, four, six, or eight equal groups. They name and write the fraction shown by one or more selected groups.
What Mastery Looks Like
- Students organize a collection into the correct number of equal groups. They identify the selected part, write its fraction, and explain how the groups prove their answer.
Common Misconceptions
- Students may use the denominator as the number of objects in each group instead of the number of equal groups. They may also make unequal groups or treat one object as the whole collection.
How to Assess It
- Exit ticket: “Maya has 12 buttons. Show one-sixth of the buttons, then write the fraction and the number of buttons in that part.”

Ways to Teach It
Give pairs 24 counters and fraction cards, then have them make equal groups and circle the requested fractional part.
Ask, “How can you prove that 4 cubes are one-third of 12 cubes?” and have students draw and explain.
Play Fraction Match by pairing cards showing grouped counters with cards labeled one-half, one-third, one-fourth, one-sixth, or one-eighth.
Pack 24 pretend crackers equally for six children, then label one child’s share as one-sixth of the whole set.
