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.
MP6.
Attend to precision.

Students use the connection between division and multiplication to estimate answers to division problems with single-digit divisors. These estimation skills help students estimate answers quickly and provide skills for learning the partial quotient method of division in a later lesson.

Content in this Lesson

  • Estimating quotients of multidigit by 1-digit numbers [E5].
  • Dividing numbers that are multiples of ten [E6].
  • Preparing to divide with one-digit divisors using paper and pencil [E7].
  • Representing division problems with situations and pictures [E1].
