Daily Dose
1. Divide: 330 ÷ 2.5
1. Subtract: 14 – 2.38
1. Multiply: 0.3 x 0.09
2.
Look at the work stations around the room for the titles: adding, subtracting,
multiplying, and dividing. Think of some key words or symbols used in real
situations that tell you to use that operation. Think of one key word for each
operation. Then raise your hand and get permission to write those
words/symbols under the correct operation. Do not write something that has
already been used.
* My goal is to analyze word problems,
determine what operation is needed, and
to then solve the problem.
Steps for Solving Word Problems:
1.
Underline the key word(s) that indicate which operation to use: + - x ÷
2.
Work out the problem. Show ALL work. Make sure it is neat and easy to
follow.
3.
Always, always, ALWAYS ask the question “Does my answer make sense?”
after solving a problem!!! You can catch mistakes by asking this simple
question.
4.
Word problems get word answers! (Write a sentence answering the question
that was asked in the problem)
