Draw a Picture“Can I draw something about the problem?”
“Will this help me solve the problem?”
“Can I draw a number line, array, or model to help me solve the problem?”

Make a Chart or Table
“Can I draw a chart to show the information from the problem?”
“How can I best display the information from the problem?”

Guess and Check
“Does this look right?”
“Could this be a reasonable answer?”

Find two numbers that add up to 25.
15 + 5 = 20
13 + 9 = 24
20 + 5 = 25

Circle Important Words
“What words give me information on what I’m supposed to do?”
“What formula should I use to solve?”

Jaden had 55 marbles. His
brother gave him 12 more. How many
marbles does he have
altogether?
I know the words more, how many,
and altogether tell me I should add!
"
Look for Patterns
“Can I see something happening over and over again?”
“Does it help me solve the problem?”

Write a Number Sentence
“What operation could I use to solve this?”
“What formula should I use to solve?”

Joe had 35 mini erasers. He gave 12 away to his
friends. How many does he have left?
35 – 12 = 23
13
Break It Into Smaller Parts
“What is one way I can break this problem into smaller pieces?”
“What do I already know about this problem?”

Find 3 numbers that add up to 45.
I know that 40 + 5 = 45
I need one more number to get three numbers.
I can break 40 into two parts.
40 = 20 + 20 so,
20 + 20 + 4 = 45

Solve a Simpler Problem
“Can I change the numbers in the problem to make it easier?”
“Will this help me solve the problem easier?”

What fraction of the circle is gray?
I know that there are six pieces total.
I know that two of those are colored.
6 – 2 = 4
So, 4 out of 6 or Rare colored.

Estimate, Check, and Revise
“What is a reasonable answer for this problem?”
“What operation could I use to solve it?”
“After I have come up with an estimate, I can check my answer to see if it’s correct. If it’s not, I can use what I know and try again!”

412 + 213 = ?
I know that 412 is almost 400 and 213 is
almost 200.
So, 412 + 213 is about 600.
I’ll add them up and check my
work!

Use Tools, Models, or
Manipulatives“Can I use paper, blocks, or tools to help me
solve the problem?”
“What picture can I draw to help me solve the problem?”

Work Backwards
“Can I start at the end of the problem to help me find the answer?”

Sofía had 98 nickels. She used some of her nickels to buy a drink. She
found 15 more nickels in her backpack. Now she has 54. How
many nickels did she use to buy the drink?
54 – 15 = 39
98 – 39 = 59
She used 59 nickels to buy her drink.
