What's on this chart
A blank number line lets the lesson decide what the marks mean. The same evenly spaced line can be labeled 0 to 20 for counting, used for forward and backward jumps, or given only 0, 10, and 20 so a child has to place the numbers between them.
Why this chart helps
Every tick remains visible and the spacing is exact; only the labels are removed. That distinction matters because a missing tick changes the scale, while a missing label creates a question the child can answer from the neighboring positions.
