Calendar honesty: This is week 1 day 3 of 18×5. It is not “the whole course.” Remaining 30-1 (24), 30-2 (17), and 30-3 (11) specific outcomes continue in weeks 3-18.

Labels (post on the board)

1. ALL STRANDS - shared launch only.
2. 30-1 REQUIRED - MAT3791 tray; mastery evidence for 30-1 SOs listed below.
3. 30-2 REQUIRED - MAT3792 tray; mastery evidence for 30-2 SOs listed below.
4. 30-3 REQUIRED - MAT3793 tray; mastery evidence for 30-3 SOs listed below.
5. CROSS-STRAND EXPOSURE ≠ mastery - hearing another tray is logged as EXPOSURE, never as an SO tick, never as a silent enrolment change.

ALL STRANDS launch (~10-14 min)

Name left/right/up/down in ordinary language on a shared parent picture. Then split: function equation vs data stretch vs object motion.

Clock ~75 min unless the school uses 60; cut the workshop block first, never the strand exit ticket. Class C parallel workshops are the default when one strand is on exclusive work.

Official outcomes (REQUIRED on home strand)

Strand	Official ID	Role today
30-1	MATH30-1-TRIGONOM-02-008	REQUIRED - Demonstrate an understanding of the effects of horizontal and vertical translations on the graphs of functions and their related equations
30-2	MATH30-2-RELATION-07-015	REQUIRED - Represent data, using polynomial functions (of degree ≤ 3), to solve problems
30-3	MATH30-3-X-03-004	REQUIRED - Demonstrate an understanding of transformations on a 2-D shape or a 3-D object, including: • translations • rotations • reflections • dilations

30-1 workshop - 30-1 REQUIRED

Clock: ~22-28 min after launch (cut workshop before cutting the strand exit ticket). Learners on this tray stay on 30-1.

MATH30-1-TRIGONOM-02-008

Official text: Demonstrate an understanding of the effects of horizontal and vertical translations on the graphs of functions and their related equations

Worked example (unique to this hour, this strand, this SO): Parent f(x)=x². Write the equation of the image after shift 6 right and 5 up: y=(x−6)²+5. The point (0,0) maps to (6,5). Match a graphed image to y=f(x+4)−7.

Level	Prompt (inside the home strand)
FOUNDATION	Shift a table of values up 2.
CORE	Write y=f(x−h)+k.
PROFICIENT	Equation from a graphed image.
ADVANCED	Composition with a translation.

Diagram: Timing: after retrieval, before independent practice. Do not open the diagram during the first retrieval prompt. Parent-to-image graphs for y=f(x−h)+k.

Independent practice: a new instance of today’s SO(s) with different numbers than the worked example. Two sentences on reasonableness.

Wrong-answer repair (do not praise):

• 30-1 SO 008: Writing y=f(x−h) as a shift left when h>0, or sliding a 30-3 shape and calling it SO 008. Repair: name the first wrong line, replace it, and re-complete the CORE tray item. Do not praise the wrong line.

30-2 workshop - 30-2 REQUIRED

Clock: ~22-28 min after launch (cut workshop before cutting the strand exit ticket). Learners on this tray stay on 30-2.

MATH30-2-RELATION-07-015

Official text: Represent data, using polynomial functions (of degree ≤ 3), to solve problems

Worked example (unique to this hour, this strand, this SO): Weekly demand looks curved: (0,15), (1,20), (2,30), (3,45). Argue for a polynomial of degree ≤3 (here quadratic-like second differences). Do not invoke 30-1 factor theorem.

Level	Prompt (inside the home strand)
FOUNDATION	Plot deg ≤3 data.
CORE	Choose quadratic vs cubic in words.
PROFICIENT	Reasonableness.
ADVANCED	Do not factor-theorem the data.

Diagram: Timing: after retrieval, before independent practice. Do not open the diagram during the first retrieval prompt. Scatter + polynomial (deg ≤ 3) with a reasonableness comment.

Independent practice: a new instance of today’s SO(s) with different numbers than the worked example. Two sentences on reasonableness.

Wrong-answer repair (do not praise):

• 30-2 SO 015: Invoking the factor theorem on a scatter plot. Repair: name the first wrong line, replace it, and re-complete the CORE tray item. Do not praise the wrong line.

30-3 workshop - 30-3 REQUIRED

Clock: ~22-28 min after launch (cut workshop before cutting the strand exit ticket). Learners on this tray stay on 30-3.

MATH30-3-X-03-004

Official text: Demonstrate an understanding of transformations on a 2-D shape or a 3-D object, including: • translations • rotations • reflections • dilations

Worked example (unique to this hour, this strand, this SO): Translate a 2-D tank rectangle 5 m east and 6 m north. Rotate 90° about a labelled corner. Reflect across a site axis. Dilate by scale 1.07 from a centre; state the inverse scale as 1/k.

Level	Prompt (inside the home strand)
FOUNDATION	Name T/R/Rf/D on a picture.
CORE	Perform one 2-D transform.
PROFICIENT	3-D or composition.
ADVANCED	Inverse of a dilation.

Diagram: Timing: after retrieval, before independent practice. Do not open the diagram during the first retrieval prompt. VIS-M30B-3DTRANS: 2-D footprint and 3-D crate (T/R/Rf/D).

Independent practice: a new instance of today’s SO(s) with different numbers than the worked example. Two sentences on reasonableness.

Wrong-answer repair (do not praise):

• 30-3 SO 004: Calling a function translation y=f(x−h) evidence for this object-transform SO. Repair: name the first wrong line, replace it, and re-complete the CORE tray item. Do not praise the wrong line.

CROSS-STRAND EXPOSURE ≠ mastery

• CROSS-STRAND EXPOSURE ≠ mastery. Log D items. Do not tick another strand’s SO.
• AI Tutor must not treat an exposure card as proficiency.

Project or clean math

Project overlay today: none. Use a clean math prompt on the home-strand tray. Do not force Sustainable Community Water & Hygiene onto work that is not genuinely that mathematics.

AI Tutor

• Load the authorized home strand only: MAT3791 (Mathematics 30-1) or MAT3792 (Mathematics 30-2) or MAT3793 (Mathematics 30-3) from the authorized profile.
• Never silent-switch a struggling 30-1 learner into 30-2/30-3 banks (or the reverse) to “make it easier.”
• Serve today’s home-strand SOs. Exposure cards are read-only.
• Never dump diploma keys or released exam wording. Original items only.
• Wrong answers: name the error and repair; do not praise.

Human-tutor handoff

Call a human tutor when: the learner cannot complete CORE after two documented repairs; an identity proof (30-1 006) is stuck after the identity map; a 30-2 017 source is unsafe or empty; a 30-3 vehicle/business number is being faked to match a hoped-for answer; distress, disclosure, or a request to change official enrolment. Enrolment changes are an office/PASI process, not a tutor action.

Diagram / whiteboard

Approved starter math30-quadratic-shift. Strand workshops may add axes/tables. Never praise a translated parabola as a circle.

Strand exit ticket (~8-12 min)

Collect only the home-strand row. Exposure ≠ mastery. Lesson MATH30B-L003.

Home strand	Primary SO	Exit ticket (unique to this lesson)
30-1	MATH30-1-TRIGONOM-02-008	CORE exit: Parent f(x)=x². Write the equation of the image after shift 6 right and 5 up: y=(x−6)²+5. The point (0,0) maps to (6,5). Match a graphed image to y=f(x+4)−7. FOUNDATION alternate: Shift a table of values up 2. Do not submit another strand’s ticket as 30-1 mastery.
30-2	MATH30-2-RELATION-07-015	CORE exit: Weekly demand looks curved: (0,15), (1,20), (2,30), (3,45). Argue for a polynomial of degree ≤3 (here quadratic-like second differences). Do not invoke 30-1 factor theorem. FOUNDATION alternate: Plot deg ≤3 data. Do not submit another strand’s ticket as 30-2 mastery.
30-3	MATH30-3-X-03-004	CORE exit: Translate a 2-D tank rectangle 5 m east and 6 m north. Rotate 90° about a labelled corner. Reflect across a site axis. Dilate by scale 1.07 from a centre; state the inverse scale as 1/k. FOUNDATION alternate: Name T/R/Rf/D on a picture. Do not submit another strand’s ticket as 30-3 mastery.
