Count and show how many to 20

What's inside this worksheet

1. Part 1

   Count and write

   Questions 1–4. Children count 11 to 20 pictures, set out in rows of five, and write how many in the box.

2. Part 2

   Ten and some more

   Questions 5–6. A full ten-frame and a second, part-filled one. Children count all the dots and write the teen number.

3. Part 3

   Draw to show

   Questions 7–8. A teen number is printed above two empty ten-frames. Children fill the first with 10 dots and draw the rest in the second.

4. Part 4

   Count on

   Questions 9–10. Four numbers in a row up to 20 with one missing. Children count on and write the missing number.

Curriculum objectives covered

Common Core State Standards for Mathematics

• K.CC.A.2Counting and cardinality

  “Count forward beginning from a given number within the known sequence (instead of having to begin at 1).”

  On this sheet: Part 4 shows four numbers in a row from 9 up to 20 with one missing, so children count on from a number other than 1.

• K.CC.A.3Counting and cardinality

  “Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).”

  On this sheet: Children write numerals from 11 to 20 in Parts 1, 2 and 4. Numbers below 11 only appear inside the counting-on rows.

• K.CC.B.5Counting and cardinality

  “Count to answer "how many?" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.”

  On this sheet: Part 1 asks how many about 11 to 20 pictures in rows of five, and Part 2 about dots on two ten-frames. The pictures are always in rows, never scattered.

How teachers use it

1Rows of five

In Part 1, ask how children counted: one by one, or by rows of five then ones. Counting 5, 10, then on is the strategy to share with the class.

2Ten and some more talk

After Part 2, ask what is the same about 14 and 17 on the ten-frames. The full frame is the ten in every teen number, which leads into ten-and-ones work.

3Counting-on check

Use Part 4 on its own as an exit ticket. A child who writes the number before the gap instead of after it is still counting from 1.

Questions teachers ask

How many problems are on this worksheet?

10 questions in 4 parts on 3 pages, with a 1-page answer key at the end.

What grade and standard is it for?

Kindergarten. Common Core: K.CC.A.2, K.CC.A.3, K.CC.B.5.

Can I print more than one version?

Yes. There are 6 ready-made versions, each with different numbers and its own answer key, and the same version always prints the same. For more, generate a new worksheet in the generator.

How is this different from the counting to 10 worksheet?

Every count here is from 11 to 20, and it adds two ten-frames and counting on. Count and show how many to 10 covers 0 to 10 and comparing groups.

Is there an Alberta version?

Alberta Kindergarten counts to 10. The Alberta version of Count and show how many follows the Alberta Kindergarten number outcome and is listed with the other Alberta Kindergarten math worksheets.
