We practice adding a single-digit number to a 3-digit number and also subtracting a single-digit number from a 3-digit number, using mental math (I show various strategies). Along the way we also look at which expression or number sentence matches a word problem, make a number pattern, and in the end, solve missing number "puzzles". Find more 3rd grade math videos at

In this 2nd part, I show how to regroup twice when there are zero tens, using the standard subtraction algorithm. The first part explains the process using a visual model and with numbers that are "written with their parts" (in expanded form): See more 3rd grade math videos: Math Mammoth Grade 3 Curriculum Practice 3-digit subtractions online:

I show how to regroup twice in subtraction when there are zero tens. The numbers are written in expanded form (for example 400 + 50 + 2) to make the algorithm as clear as possible. I also compare how it works with base ten blocks (visual model). We have to first break down a hundred into 10 tens, and then break down one of those tens into 10 ones. Then we can subtract.

In this lesson, we learn about parenthesis and how they affect the order in which we do additions and subtractions. Normally, if there are several additions and subtractions, you do them from left to right. But with parenthesis you can change that. In these examples, I draw a bubble or a "balloon" around the operation to be done first - makes math easier and colourful!
