Count On! Numbers 11 to 20

Student Task

• Count to ten together with fingers, then keep counting with the class to twenty using two children's hands.
• Do activities 1 and 2 together, counting each group aloud in fives.
• Children complete activities 3 to 6 with help. Answers are in the answer key.

Classroom Use

• Ten and more: one child shows ten fingers, a partner shows some more; the class says the number.
• Number line jump: put numbers 11 to 20 on the floor; children jump and say each number.
• Teen or tens? Say fifteen or fifty with clear stress; children hold up a card with 15 or 50.

Differentiation

Support: focus on 11 to 15 and use counters for every question. Challenge: children count backward from 20 to 11 and write the number words.

Answer Key & Assessment

Activities 1 to 5 check reading and counting the numbers 11 to 20 (answer key included). Activity 6 shows whether a child can count out a set amount.

Learning Objectives

• Say and recognize the numbers 11 to 20.
• Count groups of up to 20 objects.
• Understand that teen numbers are ten and some more.

Teacher Tips

Teen numbers are stressed on the end (fifTEEN), and numbers like fifty are stressed on the start (FIFty). Clap the stress to help children hear the difference. Counting objects in rows of five makes larger groups easier to count.
