Having a robust understanding of adding and subtracting integers also means being about to write your understanding into words. This page on the Watertank Math website helps do that AND can help those ELL/ESOL students have it translated to understand.

Subtracting two positive integers with Watertank Math helps build a foundation and gives confidence using the Watertank Math diagram. This will help when the dreaded subtracting a negative integer ( - - ) operation comes across their desk.

A 6th grader told me she hated math because "the numbers don't make sense when they go negative."
I drew a toilet on the board. Water goes in, water level rises. Water goes out, water level drops.
She said "wait, that's what negative means?"
She got every problem right after that. One picture replaced three pages of rules she'd been trying to memorize since September.

3 things math teachers hear every year when integers start:
"I don't get why subtracting a negative makes it positive."
"Which way do I go on the number line?"
"Can you just tell me the rule?"
Every one of these is a kid saying the same thing: I can't see what's happening.
Visual methods exist. Most curricula just don't include them.

Couldn't agree more Ms Herrington! With Watertank Math not only do I provide a graphic to help students illustrate their integer addition and subtraction I also have a Watertank Math apparatus teachers can make to use as a maniupluative to add and subtract integers...including the dreaded + - and - - operations!
Manipulatives are needed in HS math class. Ss can see patterns & relationships to clear up misconceptions. Graph paper has great bang for the buck!! We quickly reviewed ratios & have a shared experience for future reference. #makingconnections #iteachmath
