So, we did our Benchmark Review today and some our students did not get to work with us, and some of us just need to practice more. That made me think, hmm, 'what's the best way to help'? Here we go! This one has the top of the page missing: it is supposed to say 17. The table below shows the number of airline traverlers that departed from an airport during the first 4 months of the year. All we have to do is look at the place values. January has the lowest amount according to the place values of 1,000. 18. This shows a point marked on 2 number lines. The top line is divided into 4ths. The mark is at 2/4. The bottom line is divided into 8ths. The mark is at 4/8. 2/4=4/8 so A is the correct answer. We got this! Just remember, it's all about figuring out what we need to do. Act it out, draw it out, just do something that makes the problem make sense!
Thanks, Mrs. Froehling

Whew! We are starting a new concept that involved a little more sophisticated thinking! Equivalent fractions is the first step in reducing fractions, which happens in 4th grade for us. We understand fractions already (at least, most of us do!) and now we are taking the next step. I will add more details later, but this is a good start!
Thanks, Mrs. Froehling We are finishing up our Geometry Unit, and the things we are still struggling with involving strategies for understanding what we see. In case you haven't figured it out yet, 3rd grade Math is not really about learning 'things'; it's about learning the 'how to think'part. Because quite honestly, we are not great at thinking independently yet. And some of as adults have problems with that as well, mainly because it IS a skill, and we have either learned it, or we haven't. We use it often, or not at all. Back to our problems: We now see shapes that we may not recognize in our everyday lives, like this: These are Hexagonal prisms! How do we know? We have to use one of our strategies: Look at the identifying shape- the hexagons on the top and bottom. Or the sides, or as we say in class, the twins! What do I mean by the twins? All prisms have 2 matching shapes that are the identifiers of the prism. Look at these: See how they are named for the identifying shape? Octagonal for the two octogons, not the 8 rectangles that surround them. Still not sure? Well, let's look at a net shape. The net is what the shape looks like, when taken apart and spread flat. See all the matching rectangles? Those are not the identifiers. The octagons are. There's two and they are exactly alike. Hence, the twins! Ok, you try it. What's this shape? What about Faces, Vertices and Edges? This shape has 9 Faces (heptagon+2). It has 14 Vertices (heptagonX2). It has 21 Edges (heptagonX3). Got it? Email me if you have questions! Thanks, Mrs. Froehling PS, by the way, if you and your child saw this post, they can visit the treasure box. Just email me that you did!
One the new ways we see Multi-step problems is through being given only one actual amount, and then given operations to get to the other amounts we need in order to solve the problem. This week's homework problem looks like this: Yikes, huh?! Well, it's actually pretty straightforward if we get organized. And that's what piggy backing is, for us. Using what we already know, such as the 84 pieces of green plastic, and finding out what the others are, based on that. Now, I am ready to fill in my chart using the information. Now, we clearly have an answer! Right?
Still confused? Email me at [email protected] and I will be happy to talk you through it! Thanks- Mrs. Froehling |
