Measurement routine

Mark the attribute and keep the unit.

Mark the defining dimensions or attributes in the diagram before applying a name or formula.

Attribute: Name what is being measured.
Unit: Carry it through the result.

01
Identify the attribute, figure, scale, or time interval.
02
Record every value with its unit before calculating.
03
Check that the final unit and magnitude fit the question.

01Problem

Name the shape shown.

02 · Answeroctagon

03 · Check

Mark the defining dimensions or attributes in the diagram before applying a name or formula. This example supports the page objective: Identify defining shape attributes and partition circles and rectangles into equal shares.

Teacher sequence

Introduce, model, practice, inspect

Move through the sequence vertically. Each step has a distinct classroom decision rather than a hidden swipe panel.

01
Introduce
Set one visible purpose
- Ask learners to justify classifications by naming defining attributes. For this shapes and equal shares set, begin without a timer.
02
Model
Demonstrate the attribute-and-unit check
- Mark the defining dimensions or attributes in the diagram before applying a name or formula.
03
Practice
Assign the focused set
- Sketch, label, or decompose the figure before calculating. Regenerate only when the learner is ready for another arrangement of the same objective.
04
Inspect
Use errors to choose the next move
- Classifying a shape by orientation or size instead of defining attributes. Watch for this specifically during shapes and equal shares practice.
- Confusing perimeter, area, angle measure, and volume units. Use the worked correction as the next teaching example.
