Oh, hey y’all!
I am so excited to share this series of videos illustrating some important ideas about division, along with several methods.
Oftentimes in Math education, we tend to focus quite a bit on constructing groups of numbers through multiplication, but we don’t spend as much time on unraveling those groups with division. I would often fall into the trap of thinking that since multiplication and division are inverse operations, that if students understood multiplication, they would easily understand division just as well. Unfortunately, that’s just not the case.
Students need strong number sense, and they need a strong foundation in subtraction, place value, multiplication and division facts, divisibility rules, factors and multiples, and estimation to feel totally confident dividing larger whole numbers.
The series is just under an hour and a half from start to finish, because it’s quite comprehensive (and let’s be honest, I have a lot to say! haha!). I have broken it up into 6 different parts, so please take your time, and reach out with any questions along the way.
Part 1 explains what I feel are the three most common reasons that students struggle with division as well as some tips for overcoming them.
Part 2 illustrates Ms. B’s Key to unlocking success with division.
Part 3 demonstrates how to divide using the Area Model (sometimes called the box method).
Part 4 demonstrates how to divide using the Big 7 method.
Part 5 demonstrates how to divide using Partial Quotients.
Part 6 demonstrates traditional long division and then reviews all four methods one last time as well as some closing thoughts.
While many of us who went to school back in the 80s and 90s will most likely be drawn to the traditional long division method, it’s really important that we understand, and allow our children to explore the more conceptually driven methods of area model, big 7, and partial quotients. The best mathematicians, which is what we are trying to develop, are the ones who can flow seamlessly from one method to another. They understand the WHY (concept) which in turn leads them to understand the HOW (procedure).
Happy Math-ing y’all!
