Today, I was explaining related addition facts during math class. The two related addition facts have the same addends, but they switch places. I told them each addend wants a chance to be 1st.
For example, 2 + 5 = 7 and 5 + 2 = 7 are related addition facts. The addends 2 and 5 changed places in the equation. I was having the children use cubes, so that they had a visual and could flip the cubes over to help them write the equations.
Here are a few pictures of what I mean.
