Mathematical Standards

4.NBT.A
Generalize place value understanding for multi-digit whole numbers. (4.NBT.A.1, 4.NBT.A.3)
4.NBT.B
Use place value understanding and properties of operations to perform multi-digit arithmetic. (4.NBT.B.6)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.

Students play a game that provides practice estimating quotients. Based on their development of division concepts and procedures, students practice dividing multidigit numbers by 1-digit numbers using models to solidify their understanding. Students have opportunities to practice using multiplication to solve division problems.

Content in this Lesson

  • Solving division problems with 1-digit divisions using the column method [E1].
  • Solving division problems with 1-digit divisions using a rectangle area model [E1].
  • Using connections between multiplication and division to solve division problems [E3].
  • Estimating quotients for division of multidigit numbers by 1-digit divisors [E5].
  • Dividing numbers that are multiples of ten [E6].
