What to keep in mind:
Which operation to use = hardest part There may be two or more operationsBe sure you know:
what is being asked what you already know from the problem what you need to know in order to solve the question

Problem 1: stopping too soon
Example:Ms. Csipak is reading a geography
textbook that has 376 pages. She read 47 pages on Tuesday night, and 56 pages on Wednesday night. How many pages does she have left to read?
Use the CUBES systemWhat is the question asking?

Problem 2: Too much information
you won’t know if your answer is reasonable if you don’t understand what you are being asked to solve. Use CUBES to check your understanding of the question:
A man bought a dozen boxes, each with 24 highlighter pens inside, for $8 each box. He repacked five of these boxes into packages of six highlighters each, and sold them for $3 per package. He sold the rest of the highlighters separately at the rate of three pens for $2. How much profit did he make?

Solve and Check
At the end of a word problem: Write the answer in a sentence, the sentence should
be answering your question, if it doesn’t answer the question, it doesn’t make sense.
ALWAYS CONCLUDE WITH A SENTENCE

Don’t be afraid to DRAW!
Think of ways to combine the information into listsDecide on a starting point and work in orderKeep one item the same while others changeFill in any gapsRecord the solution so it is easy to understand
Ms. Tanya likes to stack her stickers in an orderly way on her desk. She puts 1 sticker in the first stack, 3 stickers in the second stack and 5 stickers in the third. Following the same pattern, how many stickers will she place in the sixth stack? After she makes the sixth stack, how many stickers will Liz have on her desk?
