Sounds scary, doesn't it? This is actually pretty basic stuff, and in the true style of the education gurus at the state level, we make it sound terrifying!!! What we are working on is taking an irregular shape, like this: ![]() Then we are going to split it into two parts or more, depending on the shape. Like this: Now, our next step is to find the two different areas. Like this: See how we labeled the different areas? All we have to do now is count and label (already done) then write it out so that the solution is understood by anyone who reads it.
7 x 4 = 28. That is the larger area. 2 x 4 =8 is the smaller area. Now I have to put them together, just like the picture is. 28 + 8= 36 units. 36 Units is our answer. This is the introduction. Later on, in Geometry we will get a little trickier. Right now, you may catch your darling counting squares instead of using operations. This is not always dependable, especially when we see much bigger areas, or they are not marked in clear units! Thanks! Mrs. Froehling

Here in 3rd grade, we expand our understanding of algebra (the understanding we started in 1st grade!) by bringing in "In and Out Charts". These charts are basically showing algebraic relationships. This is the type we start with- a basic addition/subtraction chart. Did you figure out the relationship? Yes, it's subtract 4. Then we move up to these: multiply or divide. What's the rule this time? You got it, multiply by 5. You may be thinking, OK, this is not too bad. Really, it's not. But 3rd graders get caught up in the "hey, I think I know this, so I will just rush on through" and that is where we get in trouble! Click on the button for a link to some practice games! Thanks!
