Reasonableness

With all the years I have been in education, whether from the side of a homework helping mother of two, the teacher for 3rd, 5th and Special Ed kids, elementary administrator, and as a math curriculum writer I don't think a day has gone by where the phrase, "Is this reasonable?" hasn't left my mouth.

So many times kids get so wrapped up in what it is they are doing that they don't stand back and ask themselves, "Is my answer reasonable?" Sure you have an answer, but go back and make sure it makes sense. This year, make this the new standard in your student's math life. The Common Core math standards require kids to explain their process and problem solving.

My favorite lesson in third grade was what I called "The Magic Brownie Pan." Students were given a bunch of information about a girl who baked two tray of brownies with a a dozen brownies in each. Four friends came over. Half had two brownies and half had three.  How many brownies were left?  There is a lot of data in the question. First of all, you need to know what "dozen" and "half" mean. You need to figure out how many brownies there are in the first place before you figure out how many are left.  Inevitably a few kids will give me an answer greater than 24 brownies, maybe they added all the brownies to all the kids to how much each kid ate.  I would joke about it not being a Magic Brownie Pan that miraculously bakes more brownies as kids are eating them. Those brownies are gone! Forever! There will be less than what was originally there, but how many exactly and how do we know we are right? What is our strategy?

Encourage your student to always check for reasonableness. The earlier they condition themselves for this type of scrutiny of their work, the greater the payoff down the road! For elementary math students, this will be key in becoming algebra-ready (also called pre-algebra) and success in higher level high school math courses.

How Students Become Better at the Math Facts

I love Stanford and the constant stream of ideas and studies that comes from math research.  The latest of which addresses the #1 concern of the week as parents enter Mathnasium of 4S Ranch. How can I stop my child from finger counting?  The Mathnasium Method definitely has tools to transition off fingers to automaticity through a series of number sense lessons and good ole practice, and we have seen over a dozen of our summer session friends invest their vacation knocking this habit specifically!

So why is fact fluency, fact recall, numerical fluency, fact automaticity (all synonyms for the action of effortless recall of math facts) so important?

"If your brain doesn’t have to work as hard on simple math, it has more working memory free to process the teacher’s brand-new lesson on more complex math."

There you go!  There is so much more math in a young student's life, they have to know their facts so they can focus on problem solving. Mathnasium's Numerical Fluency Curriculum launched in July and the immediate results have been fantastic. Things are clicking for kids as never before.  Older kids, like 4th and 5th graders, who have struggled with basic adding and subtracting skills are making my favorite sound, "OOOhhhhh!"  Connections are made!  For our younger friends on the brink of having multiplication and division added to their math mix, they are gaining steam and confidence while building their automaticity!

How well kids make that shift to memory-based problem-solving is known to predict their ultimate math achievement. Those who fall behind “are impairing or slowing down their math learning later on,” Mann Koepke said.
