Number Writing 0-20 — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. 11
2. 13
3. 15
4. 17
5. 19
6. 20
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Ten dots and three more dots. Write the number 13.
Thirteen is made of one ten and three ones, so we write 13.
2. Ten dots and five more dots. Write the number 15.
Fifteen has one ten and five extra ones, written as the digits 15.
3. Ten dots and ten more dots. Write the number 20.
Twenty equals two tens, and we write it as 2 followed by 0.
4. Ten dots and one more dot. Write the number 11.
Eleven shows one ten and one extra one, written as two ones side by side.
Part C: True or False?
Read each statement. Circle True or False.
1. The number 14 comes right after 13 when counting.
True False
Fourteen always follows thirteen when we count teen numbers in order.
2. The number 18 is smaller than the number 12.
True False
Eighteen is bigger than twelve because eighteen has more ones than twelve.
3. The number 20 is made of two tens and zero ones.
True False
Twenty equals two full tens with no extra ones, so we write 20.
