Number line 0–20
A clean 0 to 20 number line — the model behind counting on, adding, subtracting, and the first place rounding to the nearest ten makes visual sense.

What's on this chart
A number line does something a pile of counters cannot: it shows that numbers have an order and a distance. To add, a child hops forward; to subtract, they hop back; and the size of the hop is the number being added or taken away. That movement is what turns counting into arithmetic.
Why this chart helps
The same line answers questions that come later. Which ten is 17 closer to? Stand on 17 and look — 20 is nearer than 10, so it rounds up. Where does 13 sit between 10 and 20? The line makes before, after, and between into positions a child can point at rather than facts to recall.
