      Hi Gerna,
      I'm not sure I understand your question - what do you mean by motivation here?
      I'd be happy to try to help!

        My algebra used to teach this by asking students to write instructions in making peanut butter jelly sandwich (it's harder than it sounds). There is always order to where things go. Sometimes we can interchange the order of jelly or peanut butter (like doing subtract first than add). I would set up a large table with all the ingredients and tools. You can even reward them with a nice sandwich :)
