Subtraction with Regrouping with Base Ten Blocks – Summary of Steps Six hundred seventy one minus fifty eight equals six hundred thirteen. Now move to the hundreds place.There are no hundreds to take away, so write the number six below. Take away five from the six tens which leaves us with one ten. Now move to the tens place.The second number tells us to subtract five tens. We are left with three blocks, so write three below. We need to regroup a set of ten from the tens place.There are now eleven blocks in the ones place that we can take eight away from. Starting in the ones column, the second number tells us to take away eight blocks.We can't do that because there is only one block here. The second number, fifty-eight, tells us how many to take away from six hundred seventy-one. In a place value chart, represent the first number, six hundred seventy-one, with base ten blocks. Let’s solve six hundred seventy-one minus fifty-eight as our 3 digit subtraction equation with regrouping using base ten blocks. Subtraction with Regrouping with Base Ten Blocks – Example We build the first number in blocks to make the subtraction equation easier to regroup, or borrow from. It is particularly helpful when we are regrouping. Rather than just moving digits, like in the standard algorithm, we can build and break apart numbers to see how values change. Why use base ten blocks for three digit subtraction with regrouping? Modeling subtraction with regrouping with base ten blocks helps us see what is happening when we subtract. Modeling Subtraction with Regrouping using Base Ten Blocks This text teaches you how to use base ten blocks to conduct subtraction with regrouping. Luckily, there is help! You can visualize subtraction with 3 digit numbers using base ten blocks. Subtraction with large numbers can often be confusing. Subtraction with Regrouping with Base Ten Blocks
