Doubles & Near Doubles

Progression 1 (Years 1–2) Number | Using doubles and near-doubles for efficient addition with zoo/conservation pairs.

Duration: 60 mins Strand: Number Context: Penguin pairs, kākā pairs, planting pairs Representations: Dominoes, ten frames, number lines

Learning Intentions & Success Criteria

Te Mātaiaho: quantify, order, compare small collections NZC L1–2: additive strategies to 20 Key idea: use a known double

Ākonga are learning to:

  • Recall core doubles (1–10) quickly.
  • Use near-doubles (n + n±1) to solve addition.
  • Show doubles on frames, dominoes, and number lines.

Success looks like:

  • I can say doubles facts without counting.
  • I can solve 6+7 by using 6+6 and adding 1.
  • I can show my strategy with a diagram.

Teacher prompts

  • ā€œWhat double do you already know?ā€
  • ā€œIs it one more or one less?ā€
  • ā€œShow the adjustment on the number line.ā€

Kupu / Vocabulary

  • double / takirua
  • near double
  • pair / tārua
  • add / tāpiri
  • adjust / whakatika
  • difference / rerekētanga

Materials

Lesson Flow

Hook (5 mins)

  • Show penguin pairs; ask ā€œHow many in 4 pairs?ā€ Collect quick double responses.

Teach/Model (10–12 mins)

  • Flash core doubles to 10 on frames; chorally respond.
  • Model near double: 6+7 → 6+6+1; draw on number line.
  • Link to conservation: planting pairs of seedlings; add one extra seedling.

Guided Practice (15 mins)

  • Station A: Domino doubles—match to equations.
  • Station B: Near-double cards—show double, adjust +1/āˆ’1.
  • Station C: Number line hops—start from double, hop one more/less.

Independent/Extension (10–12 mins)

  • Solve 6 near-double problems; record double used.
  • Extension: create a near-double word problem (zoo or bush) and solve.
  • Support: focus on doubles to 10; teacher/peer scribe equations.

Exit Check (5 mins)

  • Quickfire: doubles 4, 7, 9; near double 8+9.

Place-based options

  • Hamilton Zoo penguin pool: count pairs (photo/virtual); double to find total.
  • Maungatautari/Zealandia: pairs of kākā or traps—estimate doubles.
Representations: frames for doubles images; number line to show the +1/āˆ’1 adjustment for near doubles.

Differentiation & Support

Scaffolds

  • Focus on doubles to 5 before extending to 10.
  • Use dot cards or domino visuals for instant recognition.
  • Keep near doubles to +1 only (e.g., 4+5).

Extensions

  • Use doubles to solve 12+12 or 15+15 with concrete materials.
  • Compare two near doubles and state which is larger and why.
  • Create a mini-quiz for a peer using doubles facts.

šŸ“‹ Kaiako Planning Snapshot

Teacher planning support for this resource — learning intentions, success criteria, and inclusive practice guidance are summarised below.

Inclusion Guidance

  • ESOL / ELL learners: Pre-teach key vocabulary (numeracy, number, doubles) using visual word walls or bilingual glossaries before the lesson. Reduce language load with diagrams and visual models. Partner-share and think-pair-share strategies encouraged.
  • Neurodiverse learners / ADHD: Break the lesson into clear segments with visual checkpoints. UDL principle: offer ākonga a choice in how they demonstrate understanding (verbal, written, visual/drawn). Provide anchor charts or reference cards for numeracy number p1 l4 concepts throughout.
  • Dyslexia: Provide audio-text alternatives for written materials. Use high-contrast fonts and generous line spacing. Allow voice recording as an alternative to written responses where possible.
