We can use base ten blocks to help us multiply numbers. Follow the steps to multiply 23 by four.

Multiply the ones. We have three ones. And we need that four times. If we take four sets of three, we’ll have 12 ones. Next, we need to multiply the tens. We have two tens. That’s 20. And we need to multiply that by four. Here’s our first set of 20, our second set of 20, our third set of 20, and our fourth set of 20.

But remember, each of these yellow blocks represent 10. And we have eight of them. Eight tens we usually write as 80. And for the final step, we’ll add the products we found from each of these together to find 23 times four. We had eight tens, which was 80, and 12 ones, which is 12. 80 plus 12 equals 92. Three times four equals 12. 20 times four equals 80. And 23 times four equals 92.
