    Help your mom cook a dinner in the kitchen. Washing vegetables may be a good choice for you. You can also learn to make a simple meal, like egg-fried rice. When you eat a meal you have cooked, you'll feel very proud.

    Choose an interesting story. Then invite your friends to perform it together. You can be the director and your friends can be actors. When you are ready, ask your family and your friends' family to enjoy the play.

    Collect your family photos. Choose some special ones with your family and make a photo wall. It's a great chance to listen to family stories behind those photos. You can also DIY a photo album and keep the photos safe for a long time.

        ④   

    Do you want to be an inventor? Be creative about finding new uses for old objects. Try to invent something with your imagination. For example, you can make a garbage can or a storage box with cardboard. You can also find a problem at your home and create something to fix it.
