Reviewed by an experienced teacher. Not yet classroom-trialled.
Prepare to teach
The teacher chooses the examples, questions and support. Before use, solve the examples and check the labelled interval on each number line: the detailed views use different scales. An aide should rehearse one explanation with the teacher, including why the zero preserves the unit of each other digit. If unit meanings are unclear, return to the teacher's prerequisite work; this is not a complete foundational-unit lesson.
A fresh written answer and explanation give stronger evidence than copying a model. Keep the worked examples and keys separate during the recheck; note any help given.
Teaching guidance and answers
Keep teacher answers separate from pupil pages. Use the approved notes for modelling, feedback and next steps.
