Learning Objectives

Students will be able to use strategies of regrouping within two digit addition problems.


(5 minutes)
  • Invite students to come sit in a large circle.
  • Bring out the base-10 grab bag.
  • Ask one of the students to reach into the bag (without looking) and to get a handful of base ten blocks.
  • Invite that student to the center of the circle to lead the class in counting the base ten blocks.
  • If desired, you can invite all students to participate by quickly moving around the circle and having each student pull out a handful of base ten blocks for counting.
  • Tell the students that they will be learning how to create base ten drawings that represent the actual base ten blocks in two digit addition. Tell the students that they will be learning how to regroup which means that numbers are rearranged before adding.
