![]() Since there is a seven in the tens place, (.) we put seven TENS in the TENS column. There were seventy-five in the water, so we'll use base ten blocks to represent seventy-five. The first step is to represent how many ducks they started with. These tools help us see what's happening when we regroup, or borrow. ![]() We can use a place value chart and base ten blocks to model subtraction. Let's subtract eighteen from seventy-five using base ten blocks on a place value chart to see how many are left. Squeaks placed seventy-five rubber ducks in the water, and took eighteen out. "Subtracting Two-Digit Numbers using Base Ten Blocks with Regrouping". Squeaks has this net so he can take out all the extra ducks! But how many ducks are left? In order to see how many ducks we have for the race, Mr. "Malfunction, malfunction!" Good thing Mr. Squeaks is helping with the annual Rubber Duck Race. Remember when subtracting two-digit numbers using base ten blocks with regrouping follow these steps: Seventy-five minus eighteen equals fifty-seven! Using Base-10 Blocks to Subtract with Regrouping Summary Be sure to record your answer on the place value chart. The third step is to subtract the tens place, so subtract one ten from six tens to get five tens. Be sure to record the seven on the place value chart. Now there are fifteen blocks in the ones place that we can subtract eight from to get seven. Can we take away eight from five? No! There are not enough blocks! Since there is not enough blocks to take away, we regroup, or borrow, a ten from the tens place and break it into ten ones. The second step is to subtract eighteen starting with the ones place so subtract eight from five. There is a five in the ones place, so we put five ones in the ones column. Since there is a seven in the tens place, we put seven tens in the tens column. In order to see how many ducks are left, we will subtract seventy-five and eighteen using the place value chart and base ten blocks. There were seventy-five ducks in the water, and Mr. How do you subtract with regrouping? Let’s take a look at this example of subtraction with base ten blocks regrouping from the video. Pay close attention to the steps for solving 2 digit subtraction with regrouping with base ten blocks, so you can see these rules in action! Subtraction with Regrouping – Example The next section will show an example of 2 digit subtraction with regrouping using base ten blocks. As you go through and subtract, keep track of what you are doing on the place value chart and in the answer. When practicing subtraction with regrouping with base ten blocks, it is important to write down the problem with the larger number first. We practice regrouping with base-ten blocks on a place value chart because these tools help us see what's happening when we regroup, or borrow. When this happens, we regroup, or borrow, from another place value so that we can continue solving. Sometimes when we are subtracting, there is not enough to take away. What Does Subtraction with Regrouping Mean? Subtracting means to take away from a group. In order to subtraction with regrouping and base ten blocks, let’s first talk about what subtraction with regrouping means and what rules for subtraction with base ten blocks and regrouping are.
