Discussion -For Problem Set 2 there is a typo in problem 6. It should say "find the probability that two positive integers do not share a common factor greater than 1, given that..."

Ok. I was staring at this for a couple of minutes thinking, "this is so stupid".

So now you’re in your classroom and getting students to talk is akin to squeezing rocks for water because math. Mathematics is serious business, no? But what if the quiet of the classroom is tearing at your soul? Sure, they’ll respond when you pull out a…

Teachers' Lounge -Strategies are so important in math, especially with the things we use all the time like counting. How do we make sure our students have those strategies? This 5th grade teacher did a little experiment with ten frames.

As an upper grades teacher, I had heard of tens frames. I had seen them, and understood them to be a tool used in kindergarten or first grade and then dropped because, let's face it: once stu...

Tens frames are a powerful visual aid in the math classroom at ANY level. The apparent lack of fluency with tens is the foundation of a whole raft of issues with place value understanding and the formation of part/whole concepts of number. Using tens frames helps the student form a powerful mental image of ten and tens which are used not just for addition but also for multiplication and division mental strategies.

With regular use the students will instantly recall compliments of 10 (e.g., 4+6, 2+8, etc) and this knowledge becomes a powerful ally in mental addition and subtraction calculations.

Tens frames can also be used to model decimal fractions where the whole frame is called "one" and each space is one tenth (because "tenths are formed when a whole is divided into ten equal parts"). So 4 dots on the frame shows four tenths, or 0.4. Students can then quickly move from naming and modelling decimal fractions to adding them without having to rely on an algorithm being taught.

commented on a post on Blogger."I made a little form special for this purpose because if one wants humans to take one seriously, one must make it obvious that one has prepared for their arrival." <-- This sentence resonated heavily with me on many levels from print outs to idea arcs that can span across the days. I think once kids believe there is a method to the madness, they start to look for patterns and connections themselves instead of just waiting for learning to be dropped upon them.

Discussion -omg, I am a failure at memory. Guess who had a really busy May and is now travelling until the end of July? I feel horrid that this totally slipped off my radar and I will try to play catchup once I get back to my regular supplies. I'll have time to do that the first week at Math Camp when I'm there for set up and have some free time. Will try to do something extra special to make up for lameness. I've also turned on notifications for this group.

Don't even worry Ashli!! It's all for fun so if can then so be it. If not then so be it.

The vegetable gnocchi is some of the best I've had. Friendly staff, superb food, great bourbon selection, enticing cocktails. I recommend unconditionally.
