Remember last week we saw a couple of videos about what the "=" sign means? Think of it as the middle of a scale and that both sides have to be the same for the balance to not tip to one side. If we were together I would have a real balance and we would take turns putting cubes in the pans on the balance. Since we aren't together we are going to use a balance on my kitchen cupboards that show that both sides in the picture are equal. Do you see that the left side has the number sentence "4+7"? You know that means "11". I used post its and showed different ways to make "11" on the other side. Both sides are equal.
Now, look at the balance below. You can draw a balance on a piece of paper and show me all the ways to make the balance equal.
