ADDITION AND SUBTRACTION By: Miss Bowlin
ADDITION Addition is when you add numbers together to get an even larger number This is what an addition sign looks like, + Adding will always equal to a larger number Equal means that its the answer to your problem This is what an equal sign looks like =
PRACTICE PROBLEM Okay let’s try some problems 4+1=? Remember that the plus sign, +, means you are adding The answer will be bigger than the number 4 and the number 1 Can you guess what the answer is?
GREAT JOB! The answer is 5! When you take 4 and bring 1 to it, it makes 5 Another way to look at it is if you have 4 animal crackers and you take one more friend to bring to the group how many animal crackers is that? 5! Lets try subtraction now
SUBTRACTION Subtraction is a lot like addition except you are taking something away. This is what the subtraction sign looks like, Lets try a problem!
PRACTICE PROBLEM 3 -2=? Remember that the, -, sign means that you are subtracting Which also means it is getting pulled away The answer will be a smaller number Can you guess what it is?
GREAT JOB! The answer is 1! We had the number 3 and we wanted to take away the number two So if we had 3 (hold up the number 3) and we took away 2 (folds fingers down to show only 1) that leaves us with 1 Another way to look at it is if we had 3 cars and mommy took one care and daddy took the other. How many cars is left? 1 Wonderful
