Mi clase comenzó el Capítulo 6 esta semana. En este capítulo,
contaré números hasta el 120 y usaré decenas y unidades
para formar números.
Vocabulario
Actividad para la casa
unidades y decenas puedes agrupar
Entréguele a su hijo un puñado de
palitos para manualidades, hilos de lana
o pajitas. Pídale a su hijo que forme la
mayor cantidad de grupos posible, atando
paquetes de 10 con una banda elástica.
Pídale que coloque los paquetes sobre un
escritorio o mesa. Pídale que ponga las
unidades sobrantes junto a los paquetes de
10. Luego, pídale a su hijo que escriba el
número.
unidades para formar decenas
