Questions about Three-Letter Blends

What does the Three-Letter Blends worksheet cover?

It practices the blends str, spl, spr and thr at the start of a word — 3 questions for Grade 2, all on Common Core RF.2.3: Read words with vowel teams, prefixes, suffixes and two syllables. 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 Three-Letter Blends practice?

CCSS.ELA-LITERACY.RF.2.3 — RF.2.3, under Reading: Foundational Skills for Grade 2. The published standard reads: “Know and apply grade-level phonics and word analysis skills in decoding words.” The worksheet assesses that standard rather than a paraphrase of it.

What age or grade is this worksheet for?

Three-Letter Blends is written for Grade 2, typically ages 7-8. It is one of the sheets on RF.2.3, so it suits any student working at that standard — including older students revisiting it and younger ones working ahead.

Does Three-Letter Blends 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 Three-Letter Blends 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 Three-Letter Blends free to print and photocopy?

Yes. Three-Letter Blends, 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.
