Teaching mental math= my death and the death of many others/vocab drawing worksheet

I was unaware that teaching mental math would give several of my students mental breakdowns.

I taught it by providing students with a hundreds chart and locating the larger number (of the two they were adding on the chart) So lets say we have 67+23. Put your finger on the 67 and then count by tens to add the next number. So add 20 to get 87 then add on your extra ones (3) to get to 90!
Here is the link to the hundreds chart we used:) We glued these into our math notebooks to use in the future.

Here is the worksheet we used for practice
Some of my kids just don't get this. Others thought it was a joke. Very frustrating.. grrrr

Does anyone else have any other ideas??



Here is a worksheet I created today to help us remember the definitions of each of them. Enjoy!

I am struggling with the same thing in my 4th grade math classes. All of my kids lack number sense (still using fingers to add problems like 5+1..... :/ ). I just received a book I bought from Amazon yesterday called "Number Talks: Helping Children Build Mental Math and Computation Strategies, Grades K-5." It came with a DVD which I popped in last night and watched. I was BLOWN AWAY with the capabilities of the students in the video!! Those are the skills my kids so desperately need but lack :(. I guess this doesn't help you much other than to let you know that I'm in the same boat and to recommend the book to you! I look forward to reading more of your posts about what you are doing in your classroom--maybe we can work through this together!!!

Isn't teaching mental math fun? :) I've been teaching mental math strategies for the last couple of weeks, so I know the feeling. The first thing I try to do is have reasonable expectations. If the kids haven't had a bunch of practice aimed at developing number sense in previous years, you can't expect them to understand in just a few lessons like you might be able when teaching an algorithm. I try to be patient with my kiddos and let them know it's OK if they don't get it right away.

It sounds like you were teaching them the "break apart" mental strategy for addition. Obviously, it's crucial that kids are very comfortable with breaking apart numbers, or "decomposing numbers" as your standards might put it (i.e. expanded form). So I spend a lot of time on this at the beginning year when covering place value.

Your kids might also need more practice with moving around a hundreds chart. Some of the activities I use are here, here, and here.

I hope at least some of this helps. Just stick with it!

(And just wait till you get to other mental math strategies like counting on to subtract and (groan) compensation, if you haven't already ;)
