Extend Arithmetic to 100 and Early Multiplication
Progress from two-digit calculation toward first ideas of multiplication and equal sharing.
Why these pages are together
This path suits learners who are comfortable calculating within 10 and 20 and are ready for a wider range.
- Learning goals
- two-digit addition and subtraction · wider calculation range · early multiplication and division concepts
- Curriculum reference
- Referenced to Korea's 2022 Elementary Mathematics Curriculum
Connects to early elementary numbers and operations; current readiness matters more than grade labels. This is a reference, not government approval or a claim of textbook equivalence.

WORKING TOGETHER
A few helpful cues
- Check fluency within 20 first.
- Ask the child to explain regrouping aloud.
- Introduce multiplication as equal groups and division as equal sharing.
COMMON QUESTIONS
Before you begin
Can we use a page from a different grade level?
Yes. Choose the number range the learner understands rather than relying only on a grade label.
Should multiplication facts be memorized first?
Begin with the meaning of equal groups, then build fact recall.
