Original component

Target criterion

Represents 620 as 6 hundreds, 2 tens, 0 ones; names 600, 20, 0 as their values.

New job title

Puppet-caption index

Source

Fictional label quantities: Puppet-caption index. First card: 503 labels. Second card: 530 labels. Third card: 350 labels. All three count the same kind of label; these are supplied counts, not actual stock or money. Use the whole values to represent, compare or order them. Own responses remain open.

Mathematical data

Invitation

Represent the first-card quantity in hundreds, tens and ones and name each part’s value.

Teacher moves

On separate work for Puppet-caption index, name one hundred as ten tens and one ten as ten ones. Build each digit’s standard value, retaining a zero as an empty place, not as an omitted label. Let the learner explain a different complete representation before recording help.

Worked possible response

503 = 5 hundreds + 0 tens + 3 ones = 500 + 0 + 3.

Guided source

Fictional label quantities: Puppet-caption index—new guided cards. First card: 407 labels. Second card: 470 labels. Third card: 704 labels. All three count the same kind of label; these are supplied counts, not actual stock or money. Use the whole values to represent, compare or order them. Own responses remain open.

Guided data

Guided invitation

Represent the first-card quantity in hundreds, tens and ones and name each part’s value.

Guided staff possible response

407 = 4 hundreds + 0 tens + 7 ones = 400 + 0 + 7.

Receive own steps

Read/hear the whole new source and name the actual requested job.

Receive the learner’s own idea in their usual communication before the staff response.

Teach the precise relationship using the separate complete model; name mathematical hints.

Deliver the complete different guided source and invitation. Receive a fresh response before its staff possibility.

Review criterion

Correctly represents the first whole and explains all three place values.

Observe and next

Record the exact relationship available in the response and the help, leaving absent evidence open. If it is missing, repeat that same relationship on a smaller complete source. If secure, change the scene/quantity or representation explicitly; do not infer annual mastery.

Access

Point, speak, sign, AAC, tactile labels, large marks or exact child-directed scribing/moving. No speed, handwriting, robot, printing or public sharing criterion.

Transfer limit

Different supplied complete new and guided contexts; no remembered original held source or real learner improvement is claimed.
