Identifying Key InformationActivities & Teaching Strategies
Active learning helps Year 1 students internalize the habit of identifying key information through movement, discussion, and hands-on tasks. These activities build focus by making irrelevant details tangible, so students can see what to ignore while solving problems. Physical engagement supports young learners' working memory and reinforces selective attention in real time.
Learning Objectives
- 1Identify the relevant numbers and words needed to solve a given word problem.
- 2Explain why certain numbers or words in a word problem are not needed to find the solution.
- 3Circle the key information required to accurately solve a mathematical word problem.
- 4Categorize information in a word problem as relevant or irrelevant for problem-solving.

Pairs: Highlight Hunt
Provide pairs with printed word problems and colored highlighters. One student reads aloud while the other highlights key numbers and words; they switch roles and compare. Pairs share one example with the class.
Prepare & details
Analyze which numbers and words in this problem are important for finding the answer.
Facilitation Tip: In Pairs: Highlight Hunt, circulate and listen for pairs justifying their choices aloud before marking anything on the page.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Small Groups: Info Sort Relay
Cut problems into cards with numbers, words, and distractors. Groups line up and race to sort cards into 'key' or 'irrelevant' piles at a station, then solve the problem. Rotate roles for fairness.
Prepare & details
Circle the key information you need to solve this problem.
Facilitation Tip: During Info Sort Relay, stand at the sorting station to quickly redirect groups who misplace a card by asking, 'Does that number help answer the question?'
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Whole Class: Detective Vote
Display a word problem on the board. Teacher points to elements one by one; students vote with thumbs up for key info or down for irrelevant. Tally votes and discuss as a group before solving.
Prepare & details
Explain why some words or numbers in a problem might not be important.
Facilitation Tip: For Detective Vote, freeze the voting process midway to ask, 'Why did you vote that word is important?' before continuing.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Individual: Circle and Check
Students receive worksheets with three problems. They circle key information independently, solve, then check against a partner. Teacher circulates to prompt reasoning.

Teaching This Topic
Teach students to treat word problems like treasure maps. Guide them to circle key numbers and underline action words that signal add or subtract. Model think-alouds where you deliberately ignore descriptive words, such as colors or names, to show what irrelevant means. Research shows this explicit modeling accelerates student adoption of the skill compared to abstract explanations alone.
What to Expect
By the end of these activities, students will confidently underline or select only the numbers and action words that matter in a word problem. They will articulate why certain details do not affect their calculations and demonstrate this understanding through collaborative and individual tasks. Accurate solutions to addition and subtraction problems will follow naturally from their focused selections.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Pairs: Highlight Hunt, watch for students who underline every number or highlight all action words without pause.
What to Teach Instead
Prompt pairs to ask themselves, 'What is the question asking?' before marking anything. If they still struggle, have them read the question aloud together and place a finger on the relevant parts only.
Common MisconceptionDuring Info Sort Relay, notice students who keep red herrings like colors or names in the 'keep' pile.
What to Teach Instead
Ask each group to verbalize how a card helps answer the question before placing it. If a card cannot be justified, it goes directly into the 'discard' box with a quick explanation.
Common MisconceptionDuring Detective Vote, observe students voting for words based solely on their familiarity rather than their relevance.
What to Teach Instead
Freeze voting after the first round and invite two students to share their reasons. Guide the class to consensus by asking, 'Does this word tell us how many?' to refocus attention on action words.
Assessment Ideas
After Pairs: Highlight Hunt, collect one problem per pair. Check if they underlined only the needed numbers and action words. Note any patterns in their choices to plan follow-up mini-lessons.
During Info Sort Relay, give each student a word problem to solve individually. Ask them to list the key numbers and words, then explain one discarded piece of information in a sentence.
After Detective Vote, pose a new problem and ask, 'Which numbers and words matter now?' Record class responses on the board to show consensus and discrepancies before moving to the next task.
Extensions & Scaffolding
- Challenge: Provide a problem with extra numbers and words. Students create a new problem using only the key information they identified.
- Scaffolding: Give students a colored pencil to circle numbers and a highlighter to mark action words, with a small word bank of possible actions (e.g., 'gives', 'takes', 'shares').
- Deeper: Students write their own word problem with three key numbers and two distractors, then swap with a partner to solve it.
Key Vocabulary
| Key Information | The essential numbers, words, or phrases in a word problem that are necessary to find the answer. |
| Irrelevant Information | Numbers, words, or phrases in a word problem that are not needed to solve it and can be ignored. |
| Word Problem | A mathematical problem presented in a story format that requires students to read, understand, and apply mathematical operations. |
| Operation Words | Words in a word problem that suggest which mathematical operation (like add, subtract, more, less) to use. |
