    I am out of school at the moment, but when we go back, I can even see using the stacking paper model to discuss order of operations. Have the students notice and wonder, find the height of the table and explain how. This will open up, “Why did you do that first?” “Why didn’t you subtract 5 first?” etc.

    If we write out the math of one of the examples as 130.75 – 5(4.95) but have them build / tell what they did step by step, this can open that discussion. The other extensions work for this too.
