The second unit of instructional and evaluation activities for a science/math curriculum in Spanish developed for first graders make up this teacher's guide. Kits five-eight, each covering a period of two to three weeks, present science and math instruction around the family. The guide lists focus, objective, and materials in English and Spanish for each learning activity; teacher instructions are in Spanish. Specifically, kits contain these themes and activities: (1) who the child is--extending experience with numbers and number combinations, introducing frame directions; (2) the child's needs and wants--observing temperature variance between common substances (water), making and using a thermometer device, adding and subtracting sets of ten, associating temperature differences with movements on a color-coded thermometer; (3) family resources--building on observation skills through taste and smell, teaching safety practices with household substances, working with number names of numerals for future activity with Celsius thermometer; (4) the child's use of resources--comparing and identifying three-dimensional shapes, introducing numerals beyond 10 through groupings of tens plus ones, practicing with numbers 0-99, using Celsius thermometer.
