  • Step-by-Step Lesson- Two digit adding and subtracting. Somewhere in between we include visuals of single digits too.

  • Guided Lesson - Operations puzzles that look for sums and differences. Followed by missing addends and subtrahends problems.

  • Guided Lesson Explanation - For the puzzles, I didn't go into too much detail because as another standard at this level points out, students should master these skills to 1000. So single digits should be a breeze.

  • Practice Worksheet - Mixed problems with input / output boxes of sums and differences under 20.

  • Matching Problems to Answers Worksheet - Find the missing addends and subtrahends by matching them to where they are missing from.
