This are the instructions of the Codey Rocky for the children:
This is the poster with more information of the activity.
This is an example of how it would be:
Also, we include here the standards that this activity achieves in Mathematics:
1.2 Conoce los números romanos y los usa adecuadamente.
2.1. Interpreta diferentes números (naturales, fracciones, números decimales, etc.) en textos de la vida cotidiana, utilizando razonamientos apropiados.
3.1 Usa estrategias de cálculo mental como una manera rápida de encontrar el resultado.
8.2. Selecciona y/o aplica la operación u operaciones correctas para resolver problemas.
For improving this activity, we could convert it in an exam better than in a review game. Also we could do less complex challenges in the “Last Challenge” because some people said that maybe they were a bit too complex for the kids.
