TpT Number Line Freebies

Since everything I seem to be posting lately deals with Number Lines, I thought I would continue the theme with a few Teachers Pay Teachers Freebies that focus on understanding and using number lines.


Number Path/Sequencing
Counting Flip Chart has children count how many items are on the page and then circle the corresponding number on a Number Path.

Help children identify missing numbers along a number line by using this Number Line Scoot Activity.


Addition
Check out this Out of This World number line game that uses addition and subtraction of numbers.  Includes a variation with negative numbers.

This fall themed Double Digit Addition activity gives students the freedom to show their own strategy on the open number line.


Rounding
Rounding to the nearest 10 or 100 can be a difficult concept for students, but using a number line gives them a visual representation that makes it easier to understand.  Check out this great Rounding With a Number Line activity and practice/homework sheets.


Multiplication
Download this simple, yet powerful Multiplication Strategies Anchor Chart.


Fractions
Number Line Lane is a nice activity to help kids use benchmark numbers when placing fractions on a number line.

Get your students up and moving as they build a fraction number line in Fraction Number Line Challenge.

Okay, so this one isn't a free one, but since it is Thanksgiving time I thought I'd share these Turkey Subitizing Cards.

Teachers Pay Teachers Freebies

I don't know if all of you know about Teachers Pay Teachers (TpT), but I learned of the site about a year ago.  Teachers share documents they have created for use in their classroom, some are for free but some are for sale.  I contribute files to the site (some free, some for sale) as well.  But as I think all teachers would agree, free is always nice...but free doesn't always mean the product is good.  So each month I will be posting files that I find on TpT that are FREE and GREAT.  This month I am going to start off with some of the free files that I have on TpT, since I made them they must be GREAT!!! :)

Subitizing Activity
I got this idea from another blog (Learning 4 Kids) but had to create the game boards myself.  So, once I had drawn them I thought other teachers might like to use them and not have to draw their own.  The basic idea is that children roll a die, take that many pom poms, and cover the circles on their board.  The first person to fill all their circles wins.


Place Value Cards
The origin of these cards can be credited to Montessori, I believe.  I first saw an adaptation of them in an NCTM publication, which I then adapted.  My version has the numerals in the corners of each card so that you can see the expanded form even when you place the cards on top of each other to create the standard form, but I also put a Rekenrek visual of each number on the back of each card because kids need to have visuals to correspond to numerals.



What the Heck is a Rekenrek???
If you asked yourself that question after reading about the activity above, then you need this file.  This file explains what they are, how you can make a homemade version, and a few activities you can do with rekenreks.
