I know at this point in the year many of you have already taught expanded form. How do you get your students to maintain their understanding of expanded form? You could leave a reminder up all year long which doesn’t take up much space. Use your classroom number line, and add these special signs to your number line. Ta-da! This is even better than an anchor chart! You can choose from space saving triangular ones…
or longer ones so that the numbers are easier to see from a distance.
If you hang your number line low enough students can help add the cards to the number line, and you can print the signs on card stock. This way students can easily attach and reattach them with velcro onto the number line (great for long term use). Tape works fine too!
You can use your own store bought number line, or you may enjoy using this number line especially created for use with these signs that includes base ten blocks already attached like shown in the instructions above.
You can go here if you are interested in purchasing this product.
“Miss _______ (insert your name here), how do you spell ________(insert your number word of choice here)?” I always have students ask how to spell different number words, only to tell students, “The best way you can.” Now you will never have to tell students again how to spell number words. Simply point to your number line. You can now have access to word cards for you number line right here:
There are smaller triangular size cards to save space. There are also larger/longer cards that can be seen more easily from a distance.
That’s not ALL folks! We have a giveaway this week! I am teaming up with Erin from A Library and Garden to offer a $50 Amazon gift card give away! This giveaway is on until Friday, October 21, 2016 so hurry and enter below now!
This STEM lesson was more fun than I had anticipated. We picked up ice cubes with a piece of string. There are few materials needed. The materials are cheap and it doesn’t take long to carry out the lesson in the classroom.
You will need:
- an ice chest or freezer
- ice cubes (the kind you freeze in ice trays) make about 5 per student to make sure you have enough
- string (like the kind you fly kites with)
- styrofoam bowls
- table salt (one container should be enough for a class of about 20)
- small cups or containers to distribute the salt
- paper towels
First, we watched a video about how salting roads helps salt trucks melt ice and snow on roadways here:
Then I explained to the students that we were going to make a string stick to an ice cube and that they would be able to pick it up. I had the students predict how long they thought that it would take to attach the string to the ice. I realized mid lesson that the kids thought I wanted them to literally tie a string around the ice cube. I had to clarify that we were not lassoing the ice cube, but that the salt would make it stick if they were patient (insert lesson about perseverance and patience here, wink wink).
These are the student directions in order.
- In your bowl of water put 1 ice cube (I passed these out when I was ready for them to begin).
- Put a pinch of salt on top of the ice cube
- Lay the string on top of the ice cube
- One team mate needs to watch time (I had this on smart board). The other team mate needs to watch the ice cube and pull on the string when the predicted time is up.
- If your string doesn’t stick, make a new prediction and try again. Switch partners.
I had a sheet in which the students predicted, and I also took some of their predictions and wrote them on the board. Some students predicted up to 30 minutes. Eventually, I reeled this in and said it wouldn’t take 30 minutes. In honesty it takes somewhere between 30 seconds and a minute. Also, I reminded students that they would only need a pinch or so of salt on the ice cube. Some students think that the more salt they use the better the string will stick and end up using WAY TOO MUCH! The important part of this experiment is the waiting. I told students that if they added salt that they would need to add it a pinch at a time.
For those students who are successful, I challenge them to make more than one ice cube stick and predict how long it will take for more than once ice cube. I walk around with a ziplock full of ice cubes during this time. When students get more than one ice cube to stick it becomes a contest about who can get the most ice cubes to stick at one time. The most I had students able to stick was 5 ice cubes. Not many kids were able to do this.
After this experiment, it is fun to discuss more of the science behind why this activity works. Because I did this during a 30 minute slot at a summer camp, we didn’t really have time to talk much.
I hope you can enjoy this experiment with your students, too!

I did this with a group of kids during my summer camp, but this could just as easily be done during a classroom engineering lesson. We built soda straw rockets to land on Mars.
What was Mars you ask? Mars was a simple circle taped to the floor with masking tape.
You need is the printable which consists of rocket fins and body, and then you need straws, tape, and a sharpened pencil…and of course Mars!
Here is a synopsis of the building directions. Students take the rectangle and wrap it around their pencil lengthwise to make a tube. Then they tape the fins at the bottom. Next they scrunch the top of the tube around the point of the sharp end of the pencil to make a cone.
Next, they pull out the pencil and insert the straw. Now they are ready to blow through the straw to make the rocket land somewhere.
I could have made it more difficult by using rulers so there would be some conversation involved, but I just made it simple and let them use yardsticks. Surprisingly, some students had the yardstick turned around and measurement still proved to be an issue.
If they didn’t reach Mars, they had to go back and redesign their rocket to make it fly closer. Now, what if they did land on Mars the first time? Well, I just made them see if they could make their rocket fly differently, for example, could they make the rocket spin while it flew.
The best part is this whole lesson and rocket parts printable are here free on the NASA website.
Here is the tool you never knew you desperately needed! I finally finished my classroom wall number line. I measured it to be nearly 41 feet long. When I put this together at home it went down my hallway and then some. This number line spans from 1-120 and has base ten blocks underneath each number. There are also gray half marks in between the numbers so that the teacher can begin introducing students to fractions while still talking about whole numbers. This is sure to be a visual reference tool which will be useful ALL year long!
You can discuss comparing numbers, greater than/less than, ordering numbers, rounding numbers, ten more and ten less, one more and one less, etc!
This number line has clear instructions for assembly, can be printed on card stock, and laminated for durability.
Tell everyone you know about this great new free animated website iknowit.com that helps elementary kids practice math skills by playing games. This site will remain FREE for at least the next year while improvements and more lessons are added. Iknowit was built by the makers of Super Teacher Worksheets and Modern Chalkboard, a SMART board lesson site.
The lessons give children immediate feedback so that they know if they have answered each question correctly or incorrectly. There are drill lessons for basic math facts–addition, subtraction, multiplication, and division. These lessons are timed. Then there are lessons based on progress in which students answer a certain amount of questions. Right now the lesson topics include addition, multiplication, division, time, money, fractions, and there are many more to come!
In the future as a teacher, you can log in and set up a class roster. You will be able to assign lessons, monitor student scores, and track their progress. You will also be able to adjust the number of hints children are allowed to have on each problem. Teachers will be able to set the amount of time students practice drills and set the number of questions a student must answer for a lesson.
Because this small business was set up by teachers, they value teacher’s and student’s constructive feedback as they venture forward with improvements to this site. You can follow them on Facebook, Instagram, or Twitter to give your input. Just imagine a website built with your feedback in mind
