Subtraction

My learning intention is to know how subtraction works.

I learned how to use subtraction in 3 different ways, using number line, place value house, and algorithm. Number lines is easy to use, when you are pulsing it is much more easier but if you are subtracting then it is a bit more harder. If you use some subtracting ideas then you might have a chance of completing it within seconds.

I learned by subtracting numbers, i had to move numbers around in the place value house to find the answer. In the algorithm i had to subtract numbers and subtract the right amount of numbers. In number line i had to subtract the right amount of numbers so it wont go over the answer.
