A scale of 2 is the first time a bar graph stops being a counting exercise. These free printable worksheets mark each gridline as 2, so a child has to read the axis before reading the bars.

The usual mistake is counting gridlines and writing that number down. A bar that reaches the fifth line is worth 10 on this scale, and a child who has only met graphs marked in ones will write 5. Every value on these graphs is a multiple of 2, so reading the axis is enough and no bar stops between lines.
Once the bars are read, the questions are ordinary subtraction and addition: how many more, how many altogether. The two-step questions, such as how many more stars and moons together than hearts, are worth doing on scrap paper, since each one holds two separate answers.
