Product Description
Color-coded, step-by-step, Addition and Subtraction anchor charts created for primary, and even intermediate grades using the standard algorithms. For some students addition and subtraction presents no issues. But for some, having a step-by-step process (algorithm) to refer back to sometimes can prove invaluable.

It is important that students understand that place value is extremely important, and that attending to precision (in the way that they write their problems) is equally critical. When we get to regrouping, suddenly students hit a wall. To get around this I have taught my students a simple strategy; "Take one from the left. Add ten to the right." At first, they don't know why they need to do this but once they realize it works they run with it, Only later do they grasp the concept that 1 from the left column is actually a 10 that is added to the right. This is the heart of Place value! If they do not understand place value, then they have difficulty working these problems.

*3/5/2019 - Added resources for non-standard algorithms for students struggling with the standard algorithm and place value. These will be helpful for students that seem to be stuck on subtracting small numbers from larger ones, even if the small number is the minuend. Learning these alternate strategies will allow students to feel successful when doing these math problems. Students will still need a rudimentary understanding (what place is what) of place value.

Standards
----------------------------------------------------------------------------------------------------------------
CCSS.MATH.CONTENT.2.NBT.B.5
Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
CCSS.MATH.CONTENT.3.NBT.A.2
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
CCSS.MATH.CONTENT.4.NBT.B.4
Fluently add and subtract multi-digit whole numbers using the standard algorithm.

Languages
----------------------------------------------------------------------------------------------------------------
I have updated the resource to include a separate file in Spanish. I am not a native speaker, relying solely on Google Translate to do the bulk of the work, I hope that the translation is accurate. No soy un hablante nativo de español. Estoy usando aplicacione para traducir mis cartas de anclaje al español. ¡Si hay cualquier error grmmatical por favor notofy yo inmediatamente!

Printing
----------------------------------------------------------------------------------------------------------------
Document dimensions 24"x31" (scaled up from a letter-size format). It will print safely on regular copy paper. Make sure that you have your settings to fit the document to print before you actually print.
Not a lot of wall space? Want to save paper? Display this on your interactive whiteboard during the lesson.

Editing
----------------------------------------------------------------------------------------------------------------
It is a high-resolution vector-based illustration created in graphic design software.
This file cannot be edited in any office software (ex, Word, Powerpoint).However, I discovered that you can use Inkscape, a FREE vector-based program, to open and edit the PDFs included in the download, although you will most likely need to make some adjustments to the file after you do. This will enable you to use vector-based graphics for cleaner anchor charts/posters.

Issues/Corrections
----------------------------------------------------------------------------------------------------------------
If you spot a typo or other errors contact me immediately for a revision. I try to proofread my own work and have other sets of eyes check it as well, but some things slip through. I can make corrections nearly immediately. Don't hesitate to contact me.

Custom Work
----------------------------------------------------------------------------------------------------------------
If you need a custom version of this file, please don't hesitate to contact me.
I want you to be happy with your purchase!
