한국어 요약

3씩 뛰어 세기를 영어로 가르쳐요. 세발자전거 바퀴처럼 셋씩 묶인 물건으로 먼저 세고, 수직선에서 3씩 앞으로·거꾸로 뛰는 대본과 손뼉 놀이를 담았어요. 2·5·10씩과 같은 생각이라 확장 쪽 하나로 다뤄요.

The big idea핵심

Counting in 3s works just like 2s, 5s and 10s. Same jump every time: 3, 6, 9, 12, 15.

The 3s are harder because the pattern on a hundred square is not easy to see. Use real groups of 3 and a number line.
