30 ii Unit 3 Pre-K Unit 3 begins the fundamental perception of numbers from zero to five. Students make and compare groups of equal or unequal size to develop the concepts of same, more, and less. To answer the question “howmuch” or “howmany” objects there are in all, studentsmust count them. The counting activities involve visual, tactile, and aural perceptions. Childrenmatch sets of objects to pictures of objects and to the written numerals 0 to 5. Emphasis is placed on understanding two essential concepts: one-to-one correspondence (every element in one set corresponds to one element in the other) and conservation of number (the number of objects stays the same regardless of how the objects are arranged). Children begin towrite symbols for numbers and are introduced to ordinal positions—first, second, third. PK-2 Develop an understanding of one-to-one correspondence and conservation of number. Compare two sets of objects to determine if they have the same number. PK-3 Identifywhich of two sets hasmore or less (fewer) objects. Determine which of two sets of objects hasmany objects or just one object. PK-5 Count the number in a collection of up to ten objects through active participation. Match sets of 0 to 12 objectswith thewritten numbers. PK-6 Write the number for a set of 0–5 objects or for a picture of 0–5 objects. PK-7 Order numbers from 0 to 10. Count forward and backward from any number between 1 and 10. PK-9 Identify ordinal numbers first to fifth. PK-30 Gather information for a graph. Use physical objects tomake a graph. Count and tally numbers. Overview Unit 3 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

During counting, the total number is not named until the last object is touched, “one, two, three—three bears in all.” A circularmotion is madewith the hand after the last bear is touched to emphasize that thewhole set has been counted.
