Kindergarten Fall Math — Counting to 100, Subitizing, Cardinality, Shapes, and Pattern
Lesson 9 30 min math.gK.f.lesson_09

Ten-frame to ten — and matching representations

Objectives
  • Students can represent quantities 6-10 on a ten-frame.
  • Students can match a ten-frame to its numeral, dot pattern, and fingers configuration for quantities 0-10.

Lesson plan

Warm-up

5 min

Number Talk — flash ten-frame cards 6, 7, 8 ('how do you see it?'). Children explain: '5 and 1 = 6.'

Teacher moves
  • Anchor every conceptual subitizing on the 5-row-full structure.
  • Use sentence frame 'I see ___ and ___ = ___.'

Direct instruction

10 min

Today we use both rows. The top row is 5. If we add to the bottom row, we go higher. Watch.

Key examples
  • This is conceptual subitizing — using the 5 as an anchor.
    model '5 + 2 = 7. We can SEE 7 without counting.'
    prompt Build 7: 5 in top row + 2 in bottom row.
  • 10 will become our most important number all year — keep an eye on it.
    model '10! All filled. Ten counters in ten cells.'
    prompt Build 10: both rows full.
  • A number is a number no matter how we show it.
    model 'All six cards show 7. Different pictures, same number.'
    prompt Show six-way representation match for 7 (numeral card, 7-dots, ten-frame, fingers, tally, word).
Checks for understanding
  • How do you see 8 in a ten-frame? (top row of 5 + 3 in bottom)
  • Are these two cards the same number? (yes — both show 7, just differently)

Single 24"x18" poster titled '7 IN MANY WAYS.' Six panels around a central large 36-pt numeral '7' in red: top — dot pattern (7 black dots in a scattered arrangement); top-right — ten-frame (5 top, 2 bottom, all filled); bottom-right — fingers photograph (a child's two hands, one full 5-finger spread + one with 2 fingers); bottom — tally marks (one diagonal 5-bundle + 2 marks); bottom-left — word 'seven' in large 32-pt black; top-left — numeral 7 itself. All representations connected to center 7 by thin gray spokes.

Guided practice

8 min
Tasks
  • Show-me 6-10: teacher calls a number 6-10; children show on personal ten-frames.
    scaffold Use a 5-anchor color line on the mat dividing top and bottom rows.
  • Six-way memory match: pairs spread the representation deck face-up; sort into piles by quantity. Each pile has 6 cards (numeral, dots, ten-frame, fingers, tally, word).
Media
M-K-F-NS-09-B Manipulative Physical / non-image

Photograph of a pile of representation cards spread on a wooden table — 66 cards total (11 quantities x 6 representations). Cards are 3"x3" square cards with high-contrast print. Some cards face-up showing the variety: numeral card '7' in red, ten-frame card showing 7, tally card showing 7, fingers card photo, dots card, word card 'seven.' Cards in pastel color border per quantity (e.g., all 7-cards have an orange border).

Formative assessment

2 min
Exit ticket
  • Show 8 on the ten-frame.
  • Match 3 representation cards that all show the same number.
scoring Both correct = mastery snapshot; 1 correct = practicing; both wrong = reteach

Closure

Moves
  • Preview: 'Tomorrow we compare quantities — which is more?'

Homework

5 min
Tasks
  • Draw a ten-frame showing 9 in your math journal. Color the counters.

Differentiation

Scaffolds
  • Color-coded top-row / bottom-row mat
  • Reduced deck (only 3 representations: numeral, dots, ten-frame)
Extensions
  • Six-way match for 0-10 in a timed challenge
  • Show same number in 3 different ten-frame fill patterns (challenge to non-standard fill)
English Learners
  • Word cards in English + home language
  • Sentence frame 'These all show ___' on table tent
Ieps 504s
  • Limit to numeral + dots match (2-way) before 6-way
  • Pre-sorted partial pile to start

Teacher notes

Today's lesson is the bridge from quantity-as-object (counters in a frame) to quantity-as-abstraction (a number can be represented six different ways and still be the same number). This is a key cognitive move per Bruner's representation theory underlying CPA. The six-way representation card deck is a classroom investment that pays off all year — keep it sealed and reuse in compare, compose-decompose, and addition lessons in Spring. Watch for children who insist that '7 dots' and '7 fingers' are 'different numbers' — that's the misconception we name and address.
