4th Grade Math 2.7, Multiply Using Partial Products

We can use place value and partial products to multiply by a 1-digit factor. We break apart the greater factor into thousands, hundreds, tens, and ones. Next, we can multiply each of these place values by the 1-digit factor. Then we add the partial products to get the full product. When we use Mental Math to multiply by place value and partial products, we begin on the left of the model for the greatest place value. We can use what we know about the Distributive Property to break apart greater factors to find products of 3-digit and 1-digit factors. We use place value and partial products. We show four word problems as examples using multiplication an addition, or multiplication and subtraction, and using the strategy Guess and Check to solve one of them.
