Why Secret Symbol Code works

Secret Symbol Code is designed to practice reasoning that can be explained from visible clues or rules through a sequence that begins when the child is asked to study the code key. Translate between symbols and meanings using a consistent secret code, then encode a short message. The opening action leads directly into the moment when the child is asked to decode the first symbol using the key.

Set up — Study the code key

No special materials are needed before the child is asked to study the code key. Keep the space simple enough that the child can move from study the code key to decode the first symbol using the key without rearranging everything. Use age-appropriate pieces and avoid small loose parts for children who may mouth objects while the child works through the first instruction to study the code key.

Step 2 — Decode the first symbol using the key

One careful attempt to decode the first symbol using the key is enough at this stage. Before the child tries to continue symbol by symbol to reveal the message, ask them to show or describe what differed from when they had to study the code key.

Step 3 — Continue symbol by symbol to reveal the message

Use the result of asking the child to continue symbol by symbol to reveal the message as a clue for the next decision. Do not move on to check the decoded phrase for sense until this step has a clear purpose.

Step 4 — Check the decoded phrase for sense

Ask the child to check the decoded phrase for sense. Compare what happens with the earlier step to continue symbol by symbol to reveal the message, then continue by asking them to use the same key to encode a new short message once the difference is clear.

Step 5 — Use the same key to encode a new short message

Let the child use the same key to encode a new short message and treat the result as information rather than simple repetition. If it is unclear, repeat that action before asking them to use the same key to encode a new short message.

What to notice before Use the same key to encode a new…

Use the attempt to continue symbol by symbol to reveal the message as the observation point. If the child understands why they are next asked to check the decoded phrase for sense, the final request to use the same key to encode a new short message should feel connected.

Make Continue symbol by symbol to reveal the… easier or harder

A shorter version can finish after the child has tried to continue symbol by symbol to reveal the message, using this support: use fewer items and make the relevant difference more obvious. An advanced version can continue to use the same key to encode a new short message after you add one plausible distractor, remove one cue, or ask the child to explain the rule.

Finish after Use the same key to encode a new…

Use the same key to encode a new short message. Once that result is clear, end the round and leave any harder variation for another time. Browse the activity search for a different mechanic, or use the activity generator.
