Each grade level comes with three units that include teaching and learning strategies that will excite children about the world of mathematics, science and language. Each unit is available in English or Spanish. But be sure to visit their Introduction page, for a good overview of the entire program. The lessons are as follows:
The Five Senses/Los Cinco Sentidos
Plants & Seeds/Plantas y Semillas (The picture above is of chile pepper seedlings!)
The Human Body/El Cuerpo Humano
Good Health/La Buena Salud
Sun and Stars/El Sol y Las Estrellas
Simple Machines/Las Máquinas Sencillas
I'm looking forward to exploring the 1st-grade units - especially The Human Body/El Cuerpo Humano since I have recently bought some other materials for teaching this subject!
