Teen Numbers Matching: Tens and Ones

About this worksheet

Teen Numbers: Ten and Some More! grounds Common Core K.NBT.1 in pictures of everyday objects grouped in tens. A box of 10 crayons with 3 loose ones, a jar of 10 stars with 5 outside, and a tray of 10 cookies with 7 beside it each become a fill-in like 10 + 3 = 13. Students then break apart the printed numbers 14, 18, 11, and 16 into 10 plus ones. Two drawing tasks finish the sheet: boxes already holding 10 dots need 2 more drawn to make 12 and 5 more to make 15. A callout at the top states the teen-number rule.

Curriculum objectives covered

K.NBT.1

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 (e.g., 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

Part 1 composes 13, 15, and 17 from pictured objects, Part 2 decomposes 14, 18, 11, and 16 by equation, and Part 3 records 12 and 15 by drawing, covering every recording method the standard lists.

What's inside this worksheet

Part 1: Count and Add

Three photos of grouped objects: 10 crayons in a box with 3 loose, 10 stars in a jar with 5 loose, 10 cookies on a tray with 7 loose. Students count the extras and complete 10 + __ = __ for each.

Part 2: Break Apart the Teen Number

Four printed teen numbers get decomposed: students finish 14 = 10 + __, 18 = 10 + __, 11 = 10 + __, and 16 = 10 + __.

Part 3: Draw the Extra Ones

Each item shows a box of 10 dots and an empty drawing box. To make 12, students figure out and draw 2 extra dots; to make 15, they draw 5.

How teachers use it

Connecting to real objects

Recreate question 1 with an actual crayon box before the worksheet. Ten in the box, three on the table, is a scene students can rebuild at their desks.

Independent work with a catch

Part 3 hides a two-step problem: students must first work out that 12 needs 2 more dots, then draw exactly that many. Count drawn dots when you mark it.

Take-home practice

Send it home with a note suggesting families count grouped items, like an egg carton plus loose eggs. The sheet's crayon, star, and cookie scenes translate straight to a kitchen table.
