Subtracting

Three concepts of subtracting are take away concept, the comparison concept, and the missing addend concept. The take away concept is taking something away from a whole. ex) 15-5=10 The comparison concept is like in the title comparing the difference and finding the answer. So if we use the same example with 15 socks and under it 5 socks we can visually see that there are 10 missing. Finally Missing addend Concept, this is when we figure out the middle. For example we have 5 stamps and we need 15 letters, we need 10 more. These are all great ways to teach children how to subtract and help them understand.
