K.CC Counting and Cardinality
Counting in order
Counting to 20, the number before, the number after and missing numbers in a count.
Short lesson: Counting
Counting tells us how many. Each number is one more than the number before it.
- One count for each object. Touch or point to each object once as you say each number.
- The last number is the total. The last number you say tells you how many there are.
- One more, one less. The number after is one more. The number before is one less.
