Think of afford like having a certain number of cookies. If you have 5 cookies and each toy costs 2 cookies, you can afford to buy 2 toys because you have enough cookies. If a toy costs 6 cookies, you can’t afford it because you don’t have enough cookies.
Imagine your energy as a battery. If you have enough energy, you can play outside for a long time. But if your battery is low, you can’t afford to play as much because you need to rest and recharge.
Picture a piggy bank filled with coins. Each time you want to buy something, you take some coins out. If you have enough coins for what you want, you can afford it. If not, you need to save more coins.
Think of time like sand in an hourglass. When you have plenty of sand, you can afford to spend time on different activities. But when the sand runs low, you can’t afford to do everything you want because you need to use your time wisely.
