Subtraction Poem

Parents- as we get into 2-digit subtraction with borrowing the students have been asked to remember this poem. After they write the subtraction problem vertically, they should always look at the ones place and ask themselves “is there more on top or more on the floor?” This will help them to determine the next step, whether they need to borrow a 10 or not. They can always use the place value chart to draw and help them visually see if they struggle with this way.
