Colors Sported by Shorkies. Yorkshire terriers are typically tan and black, although blue is one variation that is accepted. Shih Tzus bring a whole rainbow of color to the party, though, with all colors from cream to red to black to white.
Age set. In anthropology, an age set is a social category or corporate social group, consisting of people of similar age, who have a common identity, maintain close ties over a prolonged period, and together pass through a series of age-related statuses. This is in contrast to an age grade, through which people pass individually over time.
Mixed-age groupings: In a mixed-age preschool class of 2.5-5 year-olds, no more than four children between the ages of 30 months and 36 months may be enrolled and the ratios within group size for the predominant age group apply. If infants or toddlers are in a mixed-age group, the ratio for the youngest child applies. For a group of 10 children, in a Toddler/Two group with ages 12 months to 28 months, there must be 3 teaching staff to meet.
