About this worksheet
A Kindergarten teen numbers worksheet with 10 questions in three parts, all on two ten-frames. Children write the total of a full ten-frame and some more ones as 10 + 4 = ▢, write how many more than 10 a teen number is, and draw a teen number by filling one ten-frame and putting the rest in a second. Every number is from 11 to 19, so each one is ten and some ones. Every version has new numbers and its own answer key.

Curriculum objectives covered
Common Core State Standards for Mathematics
- K.NBT.A.1Number and operations in base ten
“Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.”
On this sheet: Every question shows a number from 11 to 19 as a full ten-frame and some ones: Part 1 records it as an equation such as 10 + 6 = 16, Part 2 takes it apart into 10 and the ones, and Part 3 builds it by drawing.
How teachers use it
- Say it two ways
- For each question in Part 1, have children say the number both ways: sixteen, and ten and six. Hearing ten in the word helps with fourteen to nineteen; eleven and twelve need extra attention.
- Build before drawing
- Give out two ten-frame mats and counters for Part 3. Children build the number, then draw what they built.
- Spot the reversal
- Watch Part 2 for children who write 61 for 16. Point to the full frame first: the ten is said last in sixteen but written first.
Questions teachers ask
- How many problems are on this worksheet?
- 10 questions in 3 parts on 3 pages, with a 2-page answer key at the end.
- What grade and standard is it for?
- Kindergarten. Common Core: K.NBT.A.1.
- 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.
- Why does every question use ten-frames?
- The standard asks children to see 11 to 19 as ten ones and some further ones. A full ten-frame shows the ten at a glance, so the ones are what change.
- Does it cover 20?
- No. The standard is about 11 to 19. Counting to 20 is on the Count and show how many to 20 worksheet.
