Reading and writing numbers to 20 W1-mt_fR0UtsSREU-s1

  1. 3 · Reading 13 left to right gives 1 then 3. The digit on the right, 3, sits in the ones place.
  2. 19 · Nineteen is 19.
  3. fourteen · 14 is one ten and 4 ones. That number is called fourteen.
  4. fifteen · There are 15 hearts: one ten and 5 more. That number is called fifteen.
  5. The 1, for the ten · The tens digit goes at the start, so thirteen is written 1 then 3.
  6. 15 · Fifteen is 15.
  7. one ten · The 1 in 15 sits in the tens place, so it counts one whole ten, not one single block.
  8. 9 · The ones digit of 19 is 9, so 19 is one ten and 9 ones.
  9. eleven · The 1 on the left counts a whole ten, so 11 is one ten and 1 one. We say eleven.
  10. She added the two digits instead of reading them · Digits get read by their place, not added. The 1 counts a ten and the 4 counts ones, so 14 says fourteen.
