Chapter Overview
Zero means there are no objects. It comes before 1 on the number line.
Numbers 1 to 9 introduces counting, number names, numerals, zero, and comparison. Children learn that a number tells how many objects are in a group and that the last number counted gives the total.
Counting and Number Names
- Count each object once by pointing or moving it.
- The numerals are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
- Number names include one, two, three, four, five, six, seven, eight, and nine.
- The number after a number is one more; the number before it is one less.
Comparing and Ordering
- A group with more objects has the greater number.
- A group with fewer objects has the smaller number.
- Equal groups have the same number of objects.
- Ascending order goes from smallest to greatest; descending order goes from greatest to smallest.
