The lesson
Warm-up — cover the ending
5 min- Show three longer words. Cover the ending with a finger.
- Read the root. Ask whether they know it now.
Teach — two ways in
13 min- Take an unknown word in a sentence. Read the whole sentence, not the word.
- Say what the sentence tells you it must roughly mean.
- Now take a different word and use the parts instead: cover the un-, read the root, put it back.
- Say what un- did to the meaning.
- Name the two strategies and ask which was used for which.
“Read the whole sentence first. The word is not alone on the page.”
Guided practice — four words
12 min- Pairs work out four words, saying which strategy they used each time.
- At least one word must need the parts and one must need the sentence.
- Take feedback on which was harder.
Independent practice
8 min- Students complete the word-meaning page.
- It marks which strategy each item wants.
Close
2 min- Give one new word in a sentence. Take a meaning and a strategy.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Guesses from the first letter.
Why: The first letter is decodable and produces a word fast.
Fix: Cover the word entirely and read the sentence. The guess should come from the meaning, not the sound.
Splits a word where there is no real part — 'cat' inside 'catch'.
Why: The letters are there and the strategy was praised.
Fix: Check whether the rest is an ending they know. 'ch' is not, so the split was wrong.
Uses only one strategy for everything.
Why: The first one taught becomes the whole toolkit.
Fix: Require the strategy to be named. Naming makes the choice visible and the other option available.
If they are not there yet
- Give two possible meanings to choose between.
- Words with endings they already know.
If they finish early
- Work out a word where both strategies help.
- Find a word where the parts mislead you.
- Add un- to three words and say what happens.
Exit ticket
What does the underlined word mean? Which strategy did you use?
What to look for: A named strategy. A meaning with no strategy is a guess that happened to work.

Questions about Working Out a New Word
How long does the Working Out a New Word lesson take?
40 minutes, split across 5 timed sections: warm-up 5 min, teach 13 min, guided practice 12 min, independent practice 8 min, close 2 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does Working Out a New Word teach?
CCSS.ELA-LITERACY.L.1.4 — L.1.4, Language for Grade 1: “Determine or clarify the meaning of unknown and multiple-meaning words and phrases based on grade 1 reading and content, choosing flexibly from an array of strategies.” In plain terms, work out a new word from the sentence around it or from its parts.
What do I need to teach this lesson?
Sentences with one unfamiliar word each, root and ending cards: -ed, -s, -ing, un-, re- and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: guesses from the first letter; splits a word where there is no real part — 'cat' inside 'catch' and uses only one strategy for everything. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “What does the underlined word mean? Which strategy did you use?.” A named strategy. A meaning with no strategy is a guess that happened to work. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with Working Out a New Word?
Yes — 1 printable L.1.4 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.
