Reto de hoy: Con cuatro cuatros hay que obtener el número 4 (no se pueden usar otros números, ni más ni menos cantidad de 4) ¿Lo quieres intentar? Los niños os dan algunas ideas 😉 Hoy trabajamos el razonamiento, el cálculo, las operaciones combinadas, sin contar, claro con el respeto del turno de palabra, la tolerancia a la frustración o el repaso de lo ya trabajado hace tiempo 😉 #calculo #parati #4444 #reto #clasesdivertidas
