About this worksheet

Teen Numbers Homework runs four short parts for kindergarten students, matched to the Common Core counting standards K.CC.3, K.CC.4, and K.CC.5. Students count picture sets of 11 acorns, 14 blocks, and 16 buttons, then complete a counting path from 10 to 19 with 12, 14, 16, and 18 missing. Part 3 gives verbal clues in the form "10 and 2 more makes", covering 12, 15, 18, and 13. The sheet ends with two ten-frame pictures and multiple-choice totals: a full frame plus 3 (answer 13) and a full frame plus 8 (answer 18).

Curriculum objectives covered

K.CC.3

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).

Parts 1 to 3 all end in written numerals, from the 11 acorns count to the four counting-path entries 12, 14, 16, and 18.

K.CC.4

Understand the relationship between numbers and quantities; connect counting to cardinality.

Part 3's clues bind each quantity to its numeral, such as ten and eight more being the single number 18.

K.CC.5

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.

The acorn, block, and button sets push counting to 11, 14, and 16 objects, and Part 4's frames arrange counts past ten in arrays.

What's inside this worksheet

Part 1: Count and Write

Three pictured sets to count and record: 11 acorns, 14 wooden blocks, and 16 round buttons, each with a box for the teen numeral.

Part 2: Missing Teen Numbers

One counting path runs 10 to 19 with four gaps. Students write 12, 14, 16, and 18 between the printed odd numbers.

Part 3: Ten and Some More

Four clues follow the pattern 10 and some more: 10 and 2 makes 12, 10 and 5 makes 15, 10 and 8 makes 18, 10 and 3 makes 13. Answers go in boxes.

Part 4: Ten-Frame Match

Two pictures show side-by-side ten-frames, one full and one partial (3 dots, then 8 dots). Students check the correct total from choices like 11, 13, 15 and 18, 16, 14.

How teachers use it

Weekly homework

The four parts step up gradually, so families see the progression from counting acorns to reading ten-frames without needing an explanation sheet.

Reviewing returns

Check Part 2 first. The path only asks for even numbers between printed odds, so errors there mean the teen sequence itself is shaky, not the format.

Reteach group filter

A student correct on Part 1 but wrong on Part 3 can count objects but cannot yet use ten as a unit. Pull that group for ten-frame work before the next sheet.
