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.
MP5.
Use appropriate tools strategically.
MP6.
Attend to precision.
MP7.
Look for and make sense of structure.

Constant hoppers are special math hoppers that always jump the same number of units on a number line. Using this context, students solve problems that further their study of multiplication. By using repeated jumps on the number line, students can connect multiplication to repeated addition.

Content in this Lesson

  • Representing solution strategies for problems involving multiplication using number lines and number sentences [E1].
  • Connecting repeated addition to multiplication [E2].
