Questions about Silent Letters

What does the Silent Letters worksheet cover?

It practices sorting words by their silent letter — 3 questions for Grade 4, all on Common Core L.4.2: Punctuate quotations and compound sentences, and spell grade-level words. The instruction to students is “Sort each word into the right column”, and the answer key follows on the next sheet.

Which Common Core standard does Silent Letters practice?

CCSS.ELA-LITERACY.L.4.2 — L.4.2, under Language for Grade 4. The published standard reads: “Demonstrate command of the conventions of standard English capitalization, punctuation, and spelling when writing.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Silent Letters is written for Grade 4, typically ages 9-10. It is one of the sheets on L.4.2, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Silent Letters come with an answer key?

Yes. All 3 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 Silent Letters can I print?

25 — one per student, 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 Silent Letters free to print and photocopy?

Yes. Silent Letters, 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.
