I'll give her simple problems like "x + 5 = 0, what must `x` be to make this true?" (First had to teach her the number line and negative numbers) or "2*y = 6, what is y?" (Taught her multiplication as a copy-then-add operation, ie she knows that 2*3 means to make 3 copies of 2 and then add them all together. She hasn’t yet learned the times table)
