The parts side by side make the whole on top: add parts to find the whole, subtract to find a part. Equal parts mean multiply or divide. Two bars show a difference: subtract.
Watch for: Adding the whole and a part to find the other part. Counting the parts instead of finding each one's size. Adding the two bars in a compare diagram instead of subtracting.
At home: Draw a bar for a real problem, like money saved and still needed for a toy, and label the parts.
