Rounding! Here is a quick video to help you understand what we did! It does take some practice and for some with take a little more hands on, such as with number lines and our homemade rounding roller coaster! PerimeterWe watch this and do lots of hands on work, especially with things we can move around and touch. What can you find perimeters of at home? (sorry for that crazy sentence- Of what could you find perimeters? What kinds of things can you use to find perimeters? OK, that last one is better!) Anything that has some kind of border, and that has units in that border. Like parts of sidewalks, or tiles in a room, parts of a fence, etc. Thanks! Mrs. Froehling

These are just a couple, you can search this blog for more, or google "3rd grade interactive math games"!
We hear all the time about problem solving skills, and learning the math kind in 3rd grade can put any normal, everyday, life loving kind-of-kid into a major league tailspin! Forget about tying shoes when they become untied, forget about eating when you are hungry- those are all EASY problem solving. (Yet, some of us will be in class, just sitting somewhere not working on anything... and I come to them and say, "Why are not working?" And they gaze innocently into my eyes and say, "I don't have a pencil." At which point I want to run screaming from the room because from day 1, we have practiced getting a pencil from the sharpened bin, when ever we need one.) I digress. Problem solving in math has little to do with a number sentence and a huge part to do with understanding what is happening, and what needs to be done! So, we introduce "The Window"! The Window is just a map to organize our thinking. Your child may be great at figuring out what needs to happen in a simple word problem, but what about when we get to multiple steps? The Window gives us a visual aid in arranging the information. That's all it is. Here's how to use it! Yet, they are what we have the most trouble transitioning to, from simple operations. Why? We have trouble figuring out what the problem wants us to do. Really, the toughest part is actually thinking in a way that makes the problem make sense. That leads us to our problem solving model, and that's what we are introducing this week. This is our problem solving 'Window'. Why are we using this? Because it helps us think, in an organized way, how to recognize the information in our problem. For now, we want to get familiar with how it looks, and think about ways we might use it. In class we will start practicing with it, tomorrow!
Thanks, Mrs. Froehling I feel like we just fell off the nearest cliff! We jumped into place value headfirst, but had a few set backs when we tried to segue into expanded notation. So, I am starting off with a quick video review for that! Yes, it says 4th grade, don't let that freak you out! Now, on to adding and subtracting across zero. Why both? Because they are two sides of the same problem. You have to understand that is how numbers work together! So, last year, our 2nd graders learned "more on the floor, go next door", which is just one strategy. The only problem with this, is that they really don't know what to do when there are 0s in the problem and that's why we go back to manipulatives for this. Basically, we have to understand that 100 is 10 groups of 10s, and we can change one of those 10s into 10 ones. It will take some practice, and we will move to pictures. Some students may stay in the picture form all year! Do not despair, development takes time!
Thanks, Mrs. Froehling |
