Grade K · Counting & Cardinality
Counting Objects to 10
Count objects one time each and use the final count to tell how many.
Touch one, say one
A reliable way to count is to point to or move each object as you say one number word. This prevents skipping or counting an object twice.
The last number answers how many
If your count ends at 8, there are 8 objects. You do not need to start over just to answer how many.
