- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — what and why
5 min- Give three events. For each, say what happened and why in one sentence each.
- Note that the why is often further from the event than expected.
Teach — causes come from elsewhere
13 min- Take an event. State what happened, quoting the sentence.
- Now find the why. It is usually two paragraphs earlier, or in a different section.
- Say why: texts narrate in order but explain out of order.
- Do a procedure the same way — why the step is there, not just what it is.
- Do a concept: what it is, and why it matters.
“The what is next to the event. The why is usually somewhere else on the page.”
Guided practice — three explanations
12 min- Pairs explain one event, one procedure step and one concept.
- For each, they mark both the what and the why in the text.
- They note how far apart the two marks are.
Independent practice
8 min- Students complete the explanation page.
- The passage is on the sheet.
Close
2 min- Take one what and its why.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Gives what happened as the why.
Why: The event is the most available information.
Fix: The why has to be a different sentence. Two marks, not one.
Supplies a plausible cause from general knowledge.
Why: It is reasonable and it is quick.
Fix: Mark it in the text. If it cannot be marked, it is not the text's explanation.
Looks for the why only in adjacent sentences.
Why: Causes usually sit next to effects in speech.
Fix: Look in the preceding section. Explanations often precede the narration by pages.
If they are not there yet
- One explanation rather than three.
- Give the section containing the why.
If they finish early
- Explain something with two causes.
- Find an event the text narrates but never explains.
- Explain why a procedure's steps are in that order.
Exit ticket
What happened, and why? Mark both places in the text.
What to look for: Two marks. One mark means the why was supplied rather than found.

Questions about Explaining Events, Procedures and Ideas
How long does the Explaining Events, Procedures and Ideas 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 Explaining Events, Procedures and Ideas teach?
CCSS.ELA-LITERACY.RI.4.3 — RI.4.3, Reading: Informational Text for Grade 4: “Explain events, procedures, ideas, or concepts in a historical, scientific, or technical text, including what happened and why, based on specific information in the text.” In plain terms, explain what happened and why, using the text's own information.
What do I need to teach this lesson?
A historical or scientific text with causes stated 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: gives what happened as the why; supplies a plausible cause from general knowledge and looks for the why only in adjacent sentences.
