If we count with our fingers we can make mistakes and we may not have enough fingers to do so.
COUNTING WITH OUR FINGERS

Taking away
We used the equation and then what we already knew to explain it
USING THE EQUATION AND WHAT WE ALREADY KNOW

E
Equation
As we are counting we can make mistakes or skip numbers, or repeat them.
Equals
COUNTING BACKWARDS

Drawing and counting
Writing and using the equation
COUNTING, DRAWING AND USING THE EQUATION

Equation
We counted backwards putting the big number in our heads
USING THE EQUATION AND COUNTING BACKWARDS

We counted our fingers backwards, and we asked somebody to lend us one as we did not have enough.

Equation
We used words to explain the equation
USING EQUATION AND WORDS

We used numbers and drawings and we counted backwards

put togetherWe realized that we need to read the problem carefully to know what to do
