Base Ten Blocks
We can use Base Ten blocks to show numbers. We can multiply by the ones place, then the tens place, and so on.
Breaking it Down
For this strategy, you break the number down into the ones, tens, and hundreds place (and so on) and multiply by each. This works well if you're multiplying a one-digit number by a multi-digit number. It can be tough to keep track of the multiplying if you're equation is a 2-digit by 2-digit problem.
The Box
Draw a box. If you're multiplying a 2-digit by 1-digit number (ex: 28 x 7), you would draw a box with two rows and one column. Then, you would multiply each box (ex: 20 x 7, then 8 x 7). Then, you need to add up the numbers in each box.
We are learning these different strategies to show our understanding of Place Value. It shows our steps really well. (This is called "conceptual understanding"). After we have explored different strategies, we get to use the one we like the best.
