It practises one-to-one counting within twenty — 5 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 pupils 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, in the Counting & Cardinality domain 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 Up to 20 Objects is written for Kindergarten, typically ages 5-6. It is one of the sheets on K.CC.B.5, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.
Yes. All 5 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 pupils still share a paper. Set 1 downloads all 25 as one PDF.
