Questions about Count Each Group

What does the Count Each Group worksheet cover?

It practises counting each pile after sorting — 5 questions for Kindergarten, all on Common Core K.MD.B.3: Sort things into groups and count each group. The instruction to pupils is “Count and write how many”, and the answer key follows on the next sheet.

Which Common Core standard does Count Each Group practise?

CCSS.MATH.CONTENT.K.MD.B.3 — K.MD.B.3, in the Measurement & Data domain for Kindergarten. The published standard reads: “Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Count Each Group is written for Kindergarten, typically ages 5-6. It is one of the sheets on K.MD.B.3, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.

Does Count Each Group come with an answer key?

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.

How many different versions of Count Each Group can I print?

25 — one per pupil, and all 25 ask different questions. Set 1 downloads the whole class as a single PDF. Every version is fixed to its own address, so a sheet printed today holds the same problems when you reopen it next week.

Is Count Each Group free to print and photocopy?

Yes. Count Each Group, 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.
