Grade 3 Multiplication and Division

3.OA.A.4

Full Standard

Determine the unknown whole number in a multiplication or division equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 × ? = 48, 5 = ? ÷ 3, 6 × 6 = ?

Learning Target

  • Determine the unknown number in multiplication and division problems such as in the following examples: 8 x 9 = ?, 8 x ? = 48, ? x 3 = 27, 28 ÷ 7 = ?, ? ÷ 6 = 3, and 35 ÷ ? = 7.

 

About the Math

  • Determine the unknown number in multiplication and division problems such as in the following examples: 8 x 9 = ?, 8 x ? = 48, ? x 3 = 27, 28 ÷ 7 = ?, ? ÷ 6 = 3, and 35 ÷ ? = 7.

It is critical that students can connect an equation to a problem or situation. They should connect equations with unknowns to problems as well. Students need to apply their understanding of multiplication and division to identify an unknown in an equation. Students need to see the relationship between multiplication and division. Students must see the solution to an equation on both sides of the equal sign so 7 =63 ÷ ? Students should be comfortable with the unknown number in an equation being in any position. 8 x n = 24, 4 = 32 ÷ n, 4 x 3 = n.

Essential vocabulary for this standard includes unknown product, quotient, unknown, multiplication, product, factor, and quotient .
