Os presento mi primera Unidad Didáctica en AICLE y es la correspondiente a "Perimetres and Areas". Está unidad está dirigida a alumno de 1º ESO dentro del bloque de Geometría. La Unidad está distribuida a lo largo de 8 sesiones de 55 minutos cada una.
Los objetivos de esta UD son los que se comentan a continuación:
- Saber definir la longitud y el área de una figuras plana
- Enunciar y aplicar el teorema de Pitágoras
- Cálculo de perímetros de figuras planas
- Calcular el área de figuras planas simples: triángulos, cuadriláteros, polígonos regulares y figuras plana
- Calcular áreas complejas por descomposición y composición
Para las explicaciones me apoyo en la plataforma vitutor.com que tiene contenidos de la asignatura de matemáticas según el sistema educativo español tanto en inglés como en español.
