This can be as simple as having your young kids match socks once the laundry is washed. Set a timer and have your kids match as many socks as they can during that time. Give the winner a prize that you find appropriate to the task and for your kids (i.e. a sticker, a quarter, piece of candy, fruit snack, time to play video game/watch their t.v. show, etc…).
I like to keep the kids’ toys organized into containers. When the toys are scattered across the floor, one way I will motivate them to pick the toys up is challenging them to find all the pieces/parts of toys that go into a specific container. For example, instead of telling my kids to pick up the toys, I’ll tell them to find all the cars. I’ll tell them to find all the cars. This keeps them focused on a specific task and keeps it interesting to them. I am with them while they are looking for these cars and I’m giving them prompts like, “Oh I see another car. Do you see it?” It becomes engaging and fun for the younger kids. It’s also a positive interaction between my kids and myself during a mundane household task like picking up toys.
For older kids, consider implementing a sticker chart or check off chart.
You can build incentives/rewards into the chart as your kids complete the tasks. With the kids at home, you might have to give daily incentives/rewards and weekly rewards. Keep the daily incentives/rewards for the small things like stickers, quarters, candy, etc. And keep larger incentives/rewards for accomplishing weekly rewards.
