In this anchor chart, I try to show the distributive property at work in the word itself (the i and the r are being distributed into the words). I also color-coded with arrows and end product, as well as the different terms being multiplied.
A good anchor chart is not too busy. It was explicitly taught that signs are kept from numbers with a greater absolute value not whichever is greater (otherwise all answers would be positive!). However on my chart I used the word "more" in quotes and used the same underlining for numbers with greater absolute value.
My students struggled with creating equivalent expressions that "add the opposite", but I found that reminding them to keep the first number the same helped tremendously. (Reminiscent of "keep, change, flip" of dividing fractions)
