Set 1. Prints on its own sheet.
It practices counting a set laid out in rows, row by row — 6 questions for Kindergarten, all on Common Core K.CC.B.5: Count a group of up to 20 objects and say how many there are. The instruction to students is “Count and write how many”, and the answer key follows on the next sheet.
CCSS.MATH.CONTENT.K.CC.B.5 — K.CC.B.5, under Counting & Cardinality for Kindergarten. The published standard reads: “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.” The worksheet assesses that standard rather than a paraphrase of it.
Count Rows of Objects to 20 is written for Kindergarten, typically ages 5-6. It is one of the sheets on K.CC.B.5, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.
Yes. All 6 answers are generated from the same problems as the questions, so the key cannot drift out of step with the sheet. It starts on a fresh sheet of paper, after the questions, so it is not handed out with the class by accident.
25 versions, of which 24 ask genuinely different questions — this skill does not have 25 distinct questions to give, so the rest reorder them and no two students still share a paper. Set 1 downloads all 25 as one PDF.
Yes. Count Rows of Objects to 20, its answer key and its 25 versions are free to print and photocopy for your own class, with no account, no email capture and no subscription at the download step. Please do not resell them or republish them as your own.
