Once upon a time, in a colorful Number Town, Number 20 felt lonely. It visited the Tens House and Ones House, rooms for number friends. Number 20 was 2 tens plus 0 ones. Two tens lived in the Tens House. Zero held the Ones place. There were no ones, but zero was important. It kept the place safe. Then Number 4 arrived. Where should 4 go? [Pause.] Yes! The Ones House. Now 20 and 4 made 24: 2 tens plus 4 ones equals 24. Next came 35. Can you find its tens and ones? [Pause.] 3 tens and 5 ones! Then ten Ones joined hands. Sparkles flew: 10 ones equals 1 ten! At last, 42 entered the houses: 4 tens and 2 ones. Every digit has a home. Remember: in Number Town, tens go first and ones go next. The houses help every digit stay in the right place!
