In Math today, we continued to review how to use variables to write equations. Check out the example below:
Students needed to read the word problem and then write an equation that could be solved to answer the problem. The first thing I always do when I am reading a word problem is to highlight or circle the important numbers. So, Mary-George has 4 buckets of clams. Altogether she has 120 clams. That word "altogether" is a great clue! That means that my total is going to be 120 clams. I can write " = 120" because I know that the equation will equal 120. Then I need to decide what operation I am being asked to use. In this problem, Mary-George has 4 buckets with the same amount of clams in each bucket. Four groups of an equal amount. That is the same as saying "clams in the bucket + clams in the bucket + clams in the bucket + clams in the bucket = 120" or "4 x clams in the bucket = 120." Now, I should use a variable to represent my unknown value. The unknown value is the amount of clams in each bucket. I chose to use "c" to represent clams. Now my equation reads "4 x c = 120," which is a great equation that can be solved to solve this word problem!

Hi ms.barrington.so i know that i have a lot of questions but i have a white board at home and did this same question about the clams,so i actully wrote it like 120=4xb and 120=bx4 then 120/4=b,120/b=4.would this be correct,cause it is weird i underswtand most stuff in this unit but this is confusing.so i was just wondering is that still correct?because you wrot it like 4xb=120 i wrot it likethe other waqy around.

These equations are all great! They all represent the story problem and they can all be evaluated to find out what b equals. Remember, as long as both sides of your equation are equal, it is a good equation. There is no wrong way or backwards way to write it :)

Mary-George has 4 buckets of clams. Altogether she has 120 clams. We need to find out how many clams are in each bucket.
