5 Ways to Dig Deeper with Number Lines

Hi, friends! I'm Blair from One Lesson at a Time, and I'm so excited for my first post over here at the Primary Chalkboard! I am a number line fanatic. They are such an amazing tool to use with so many different math skills. By helping students flexibly use a variety of number line strategies, we can really help them develop deep and meaningful number sense.

Today I am rounding up 5 of my favorite applications for number lines. I'll link you to a few other posts that I've written and some resources that I've created that will help you dig deeper into number line strategies in your classroom.

And away we go!

Rounding can be a super frustrating skill to teach. There are a lot of "tricks" for teaching rounding - and once I ditched them, my quality of life improved significantly. By introducing rounding on a number line, students are immediately set up for success with the underlying conceptual understandings that help us get why we round up or down. 

I don't want to oversell this, but this post on my blog has more information about the lesson that changed my life. Dramatic? Yes. Accurate? You betcha.

Open number lines are probably my current favorite thing, surpassing even my fondness for cheese. Ok, well, I really, really love cheese, so that may be a bit of an overstatement. But I really do love them. 

I was actually inspired to really get into open number lines after seeing this piece of mathematical artwork by one of the 3rd graders at my school:

I MEAN. Is that not a thing of beauty?!?! In this blog post, I do my best to demystify open number lines and show tons of different ways that they can be used as a problem solving strategy.

"Zooming in on a number line" is a quick and easy activity I like to do with my students at least a few times a month. This really helps students with a few fundamental understandings. It's a great way to illustrate which numbers "live" between the intervals when the intervals are greater than 1. You can click over to this post on my blog for more information and pictures.

The Common Core standards for 3rd grade (specifically 3.NF.2) are very explicit about the need for students to be able to understand and represent fractions on number line diagrams. I love using interactive notebooks to teach math, and find them to be particularly helpful with this standard. We first use a flap book to break down the vocabulary....

Then, I give them some guided, hands-on practice in partitioning number lines into fractional parts.  I find that one of the trickiest things about fractional number lines can be that students are often tempted to count the lines rather than the intervals. Allowing them to physically fold the number lines is super helpful in clearing up this common misunderstanding. 

Once they've gotten the hang of it, they are ready for a few more practice activities.

The activities pictured above are all part of my interactive notebook pack for 3.NF.2, which is available in my Teachers Pay Teachers store.

Elapsed time is another one of those skills that many teachers prepare to teach by tripling their daily coffee consumption. It can be tricky stuff, no doubt. And CCSS 3.MD.1 ups the ante by explicitly stating that students need to be able to represent elapsed time on a number line diagram. This really wasn't something that I had ever done prior to the Common Core, so I initially felt some trepidation about it. But, HOLY GUACAMOLE. Using number line diagrams for elapsed time was a game changer for my kiddos. It REALLY helps them "get it". So I am now a full-on believer. I use these elapsed time lines to tackle this standard with my students - they are available in my TpT store.

Thanks so much for stopping by Primary Chalkboard today! I'm so excited to be an official "Chalkie", and I can't wait to come back soon and share more teaching ideas with you. 

Happy Teaching!

Common Core Writing Rubrics

Aloha everyone! It's Corinna from Surfin' Through Second. I hope the New Year is rolling right along for you and your class.

Today I wanted to share some Writing Rubrics for 2nd grade.

Last year I attended a workshop where we sat down and broke apart the 
Common Core standards at 2nd grade for each writing strand.

If you would like more details on the process you can check out my full post {HERE}.

It was a long process, but great to really understand what to look for in a student's writing.

Each rubric is broken down into 5 areas -Introduction, Development/Evidence, Conclusion, Organization and Language Skills (which apply to each strand). Click on the pictures to download each rubric.

I have an editable version that you can grab on Google Docs---> {HERE}

These are a great starting point and you can easily adapt and make kids friendly versions for your classroom.

I hope you find these helpful!  

December Writing Freebies

Hi Friends!!! It's Latoya of Flying into First Grade!!!

I am here to bring you some writing ideas for the month of December!!!
These are great freebies that can be used to practice many types of writing during the holiday season.





Happy Holidays!!!

Prepping Early with a Freebie!

Hi, friends! It's Laura from Peace, Love, and First Grade!

When I read Katie's post yesterday, I thought about the hustle and bustle of the holidays and how we, as teachers, can find ways to lessen the stress. 

One thing I like to do is prep ahead.

Years ago, I learned I removed some unnecessary stress if I prepped weeks in advance. 

Don't get me wrong, things always come up, but I want to be prepared if they do. 

Being prepared includes making sure all my classroom resources are printed and ready to use before they are needed. 

In first grade, we use a lot of printable math resources-
number cards, number grids...tons of number references, including number lines. 

Well, I'm all about seasonal and holiday fun, and my kiddos enjoy using them, too.

If you like changing out references with the seasons, then here are a few freebies for you-

number lines 0-10. 

Even though, we are adding through 20, the Singapore Math program we use is based on ten, 
so we'll use these number lines all year. 

And honestly, many of my sweet friends still need visuals to help with equations,
 especially with those tricky MISSING ADDENDS! Grrr!

Here are three different winter number lines from 0-10, color and b/w.

And, if you still need fall resources,
 here are three different fall number lines from 0-10, color and b/w, as well.

I hope you can use these! 
Happy Sunday, friends!

Informational Mentor Text List (for every 2nd Grade CCSS)

Wanna know what is funny? EVERY grade in our K-5 school is in the middle of an informational text unit RIGHT NOW. Totally by coincidence or teacher think-alike? Not sure. All I know is that our library is cleared out!

Thankfully, I thought ahead! At this time last year I started searching for copies of books that I was certain would be perfect for a mentor text book cart. I stocked up and found about 35 excellent books that are my go-to books for "Everything Informational Reading Related".

I am happy to share my suggestions for awesome texts that go with each Common Core standard. This list is specifically for 2nd grade, but it could also be used with most 1st grade standards as well.

(If you would like to download the list in a neat, easy pdf format, click here.)

Having these books on the ready has saved my butt this year! Here we were today comparing two books presented on the same topic.

I feel like they are learning a ton right now! Now, let me back up and say that we do work with informational texts ALL year long. But this is the time we REALLY delve in! How about you? Do you just mix them in throughout the year or do you have a unit specifically focused like me?
