Singapore Sunday: Subtraction Video Tutorial


Hello Darlings! I noticed I have gotten a little lax (ok, like nonexistent) with my Singapore Sunday posts. I know not everyone uses Singapore Math, but the strategies are awesome and can be used along side any math program.

I wanted to share with you how we start off teaching subtraction with our kiddos. Singapore Math focuses on introducing kiddos to a concept with the pictorial stage and then progressing to algorithms from there.  Kiddos gain a deep understanding of place value which allows them to understand why they must borrow or carry. In Singapore Math, this is called trading, because that is what you are doing.  You are not actually "borrowing" because you don't give back what you borrowed...

If you do not teach Singapore Math and you have already taught your kiddos how to borrow while subtracting, then I would use the Place Value Discs for your struggling kiddos. You don't need the discs, I just have my kiddos draw circle and the value inside most of the time anyway    It is a great way to take them back to the beginning to help them understand why they are crossing out numbers and so on.  I hope this helps!

I'm linking up with Classroom Freebies to bring you this awesome resource!

    1. I am so glad you use Singapore Math as well! Is it the video that isn't playing for you? It is working on my computer, so I don't know what the deal is... It plays in windows media player... I don't know if that makes a difference.

    2. Amy, it works for me now. Thanks! We have been using Singapore Math since kindergarten and love the concrete > pictorial > abstract approach of the program.

    1. I really like it! It was hard to implement at first because our third graders didn't have the background when we started out. Now it is amazing! My kiddos know SO much more than they did with our other math programs. They have a deeper understanding of the why AND the how. If you have any more questions, don't hesitate to email me! teacherchicksblog@yahoo.com
