stop the video at the end of Perimeter! But Area is coming up!We did pretty well with this, but again, the tricky part is getting from a word problem! We even took it a step further, and tried to make our own word problem, using our pretzel sticks to create them! So, what is Perimeter? It is the number of units around the outside of a shape/object. How will it look in an assessment? This is why we are working at a level that is so much more challenging than 2nd grade. This is why grades are lower. This is a whole different conceptual level!We are really working on building these higher level thinking skills and practicing ways to get there! I was in Costco the other night and saw this book, and when I saw the stories, I was hooked! Check it out! It has great stories and think alouds!
Thanks, Mrs. Froehling

Who knew this would be such a challenge? OK, let me clarify- rounding was not the challenge. We can do this! But pretty much in isolation, meaning, we can look at a number and decided whether we go up to the next 10s or go back to the last 10s. Same thing with the 100s. And then.... (ominous music) We put it in a word problem. Clutch at your chest! Hyperventilate! Break out in a cold sweat! And that was just me! Seriously though, if you watched our video about word problems, you can see what might be happening, such as not rounding the right amount, rounding too far, too little, and so on. And the thing that happens most often? Not rounding at all!!! (phew, take a breath...) So here's what we are trying to do to help ourselves. Look for words like: approximately about estimate round rounding to Now, I am not a huge fan of key words, because they can trick us! But these guys, they pretty much always are talking about rounding or compatible numbers. What are compatible numbers? When estimating, compatible numbers are numbers that are close in value to the actual numbers, and which make it easy to do mental arithmetic. (from MathGoodies.com) Basically for us, that is just a form of rounding. For us. In 3rd grade. At the beginning of the year. OK? This chart is from Indulgy.com and it shows the basic strategy we use when rounding. If your child is still struggling, this might help as well: Hopefully this gives a little help.
So, how can you help your student? Rounding in real life!!! Ask them, about how many.... Can you estimate how many..... How many ... do you think there are, approximately? Thanks, Mrs. Froehling Seriously. We panic! But then we calm down and start to think through the problem. Sort of. Most of my kids get into a bit of a rush and scurry through a multi step problem as though it was a backyard full of doggy doo, and the gate on the far side was made of ice cream that might melt in the sun if they didn't get there fast enough! Well, slow down, partner! Let's walk and talk through the steps in our handy, dandy, problem solving window. Please, please forgive my nervousness, spelling mistakes, and editing mistakes. This was a loooong video to make, but I wanted you to understand what the "thinking" is about and how it should look. When your student is problem solving, they may be ahead of this or still need every step. The thing is: I want them to UNDERSTAND the problem and WHAT NEEDS TO BE DONE to solve it. They could use pictures instead of the words. They could use a part/part/whole mat. They could use any of their strategies to help them.
The number one problem so far- RUSHING! We have to slow down and understand first. Then plan, do and make sure it makes sense! Thanks! Mrs. Froehling Get it? In the House? Like the Place Value Houses we learned back in First Grade? Well, last week's Project Based Learning during RtI time was about cooperative learning groups coming up with a verse in our Place Value Rap that described or had components of a part of Place Value. Those included: Expanded Form, Expanded Notation, Digit, Pictorial Form and so on. Groups worked very hard, and did some great analyzing of their verse, to make sure it did what it was supposed to do, namely, inform others about the place value component they were working on. So here is our finished Rap!!! These kids rocked it! I mean, they Rapped it!!!This week is about using that Problem Solving model and getting it down so we can use it FOREVER!!!!9/13/2015 What problem solving model, you ask? |
