Day 13 · Write a route someone else can testYear 2 Maths · T1 W3–4 · Day 13 lesson

Code: AC9M2SP02. Goal: compose and test a route with a marked start and finish. Prepare: Map A, two counters, paper arrows.

1. Invite · 2. Say, “We need a path to return a book from B2 to A3. How will someone know where to begin?”
2. Model · 5. Label Start B2, say “left to A2, down to A3”; make two arrows. Give the route to a second counter and actually follow it. Name Finish A3 and check against “book returns.” Show that “go left and down” without a start is incomplete.
3. Guided · 6. As a class, route from C3 to A3 with two left moves. Ask for another valid path, such as C3 up to C2, left to B2, left to A2, down to A3. Test rather than assume “shortest” is the only good path.
4. Choice · 6. Choose a D13 card. One child writes/speaks/places arrows; another follows exactly. If it fails, keep the first version and repair one instruction.
5. Exit · 4. Prompt: “Route from D4 to C4.” Expect one move left with start and finish marked. Ask whether a different route could also arrive, and why this one is simple.
6. Note · 2. Photograph only the route sheet if school policy allows; otherwise transcribe. Record initial/revised route separately.

Access/home/extension: Sentence strips “Start ; move ; finish __”, textured arrows, AAC directions; adult scribe follows the child's choices. Extension: compare two valid routes by counting steps, not by declaring one correct merely because it differs.
