How much do a pencil and sticker cost? Youngsters use a bar diagram to find the cost of a sticker that is twenty cents less than the cost of a pencil. Given the prices, learners must find the cost of the sticker in order to find the cost of the two items put together. The activity is great for young mathematicians to practice adding and subtracting using bar diagrams, but it is also ideal to use as an instructional tool.
