Set 1. Prints on its own sheet.
It practises comparison along the vertical — 12 questions for Kindergarten, all on Common Core K.MD.A.2: Put two objects side by side and say which is longer or heavier. The instruction to pupils is “Write < , > or = between the heights”, and the answer key follows on the next sheet.
CCSS.MATH.CONTENT.K.MD.A.2 — K.MD.A.2, in the Measurement & Data domain for Kindergarten. The published standard reads: “Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference.” The worksheet assesses that standard rather than a paraphrase of it.
Which Is Taller? is written for Kindergarten, typically ages 5-6. It is one of the sheets on K.MD.A.2, so it suits any pupil working at that standard — including older pupils revisiting it and younger ones working ahead.
Yes. All 12 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 — 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.
Yes. Which Is Taller?, 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.
