Which indicator describes prek 4 counting to 20 and beyond?

• A. Counts to 20 while walking across room
• B. Counts 10 plastic worms and says I have 10 worms
• C. When asked 'What comes after six?' says 'Seven'
• D. Counts to 20; counts 10-20 objects accurately; knows the last number; tells what number 1-10 comes next in order by counting

Answer: (D)

The main idea being tested is a child’s ability to count to twenty and show understanding of number order and quantity beyond ten. The best indicator demonstrates that the child can count to twenty, count objects in the 10–20 range accurately, recognize what the last number in that range is, and identify what number comes next in the sequence by counting. This shows both understanding of quantity (counting objects correctly) and sequencing across a broader range, not just a small, rote count.

The other examples fall short in different ways. Counting to twenty while moving doesn’t prove accuracy or one-to-one correspondence with objects. Counting ten objects and saying the total confirms a single, small set’s quantity but not the ability to handle larger counts or understand sequence beyond ten. Knowing what comes after six shows knowledge of the immediate successor but only in a limited, single-step context, without demonstrating counting to twenty or handling larger sets.
