Virginia SOL 3.CE.2.b
The Standard
Use inverse relationships to write the related facts connected to a given model for multiplication and division of whole numbers through 10 × 10.
Virginia Standards of Learning for Mathematics · The student will recall with automaticity multiplication and division facts through 10 × 10; and represent, solve, and justify solutions to single-step contextual problems using multiplication and division with whole numbers.
Teacher's field guide
What This Standard Means
What Students Need to Do
- Students read an array or equal-groups model and identify the two factors and the total. They use those three numbers to write connected multiplication and division equations.
What Mastery Looks Like
- Given an array or equal-groups model, students identify both factors and the total. They write two multiplication equations and two matching division equations, then explain how the equations are connected.
Common Misconceptions
- Students may switch the quotient and divisor or assume division works in either order. They may also use numbers that do not match the rows, columns, and total in the model.
How to Assess It
- Show an array with 5 rows of 7 dots. Ask students to write its four related equations and circle the product or dividend in each.

Ways to Teach It
Build a 4-by-8 array with tiles, label the dimensions and total, then write the four related equations.
Ask students to explain in writing how 6 × 7 = 42 helps them solve 42 ÷ 6.
Play Fact Family Match by pairing array cards with cards showing the two multiplication and two division equations.
Arrange 30 classroom chairs into 5 equal rows, find the chairs per row, and record all related equations.
