Mathematics Standards

4.NBT.4
Generalize place value understanding for multi-digit whole numbers. (4.NBT.A.3)
4.NBT.B
Use place value understanding and properties of operations to perform multi-digit arithmetic. (4.NBT.B.5)
4.OA.A
Use the four operations with whole numbers to solve problems.(4.OA.A.3)
4.OA.B
Gain familiarity with factors and multiples. (4.OA.B.4)

Standards for Mathematical Practice

MP1.
Make sense of problems and persevere in solving them.
MP2.
Reason quantitatively.
MP3.
Construct viable arguments and critique the reasoning of others.
MP4.
Model with mathematics.
MP5.
Use appropriate tools strategically.
MP6.
Attend to precision.

Students estimate the number of steps they would take if they walked for one hour. They devise, carry out, and communicate their problem-solving strategies. Students also review each other's work to provide feedback that informs a revision of their written explanations.

Content in this Lesson

  • Collecting and using data to solve problems.
  • Estimating products [E6].
  • Choosing appropriately from among estimation, mental math strategies, and paper-and-pencil methods [E8].
  • Solving extended-response problems and communicating solution strategies [MPE1–6].

E6.
Estimate products.
E8.
Choose appropriately from among estimation, mental math strategies, and paper-and-pencil methods to multiply whole numbers.
MPE1.
Know the problem. I read the problem carefully. I know the questions to answer and what information is important.
MPE2.
Find a strategy. I choose good tools and an efficient strategy for solving the problem.
MPE3.
Check for reasonableness. I look back at my solution to see if my answer makes sense. If it does not, I try again.
MPE4.
Check my calculations. If I make mistakes, I correct them.
MPE5.
Show my work. I show or tell how I arrived at my answer so someone else can understand my thinking.
MPE6.
Use labels. I use labels to show what numbers mean.
