Review: Repeat, Repair and Decode Patterns
Expand repeat groups, check their scope and translate ordered symbol messages.
Bring the unit skills together
Use these 4 new cases to check your reasoning. Choices are temporary and are not saved to an account, sent to staff or recorded as school grades. Download your current review choices before leaving or reloading.
The download contains your current choices and any checked feedback. Keep the separate transfer-task work in your own document; downloading its instructions does not mark it complete.
Use the skills in a new task
Use key P = dot and Q = square. Create the target dot, square, dot, square, dot, square using a repeat rule, encode it, and repair this draft: repeat three times: dot; after the repeat: square.
Work on paper or in your own document. Explain the choices you made.
- Write the two-action group dot, square and repeat it three times.
- Expand six actions in the correct order.
- Encode the target as P Q P Q P Q.
- Explain why the draft makes only four actions and move square into the group.
Compare with a model response
Repeat three times: draw a dot, then draw a square. Expansion: dot, square | dot, square | dot, square; 3 × 2 = 6 actions. Code: P Q P Q P Q. The draft expands to dot, dot, dot, square, only four actions. Putting square inside the repeat repairs it.
A different response can also meet the criteria. Compare the evidence and reasoning, rather than copying the wording.
