This is a math worksheet bundle that teaches students to recognize if they have enough money to purchase an item. It uses a number line to help them see why they can or cannot purchase the item. You start at 0, find the amount of money you have in your wallet and circle that number. Then you draw an arrow from 0 to the number. Any number under the arrow you can afford, and any number not under the arrow, you cannot afford. This comes with an introduction sheet and 8 2-page worksheets.
