Make sense of problems and persevere in solving them. Mathematical Practice 1 !!

!

When presented with a problem, I can make a plan, carry out my plan, and check its success.

BEFORE…

DURING…

AFTER…

EXPLAIN the problem to myself. MAKE A PLAN to solve the problem ! What is the question? ! What do I know? ! What do I need to find out? ! What tools/strategies will I use?

PERSEVERE (Stick to it!) MONITOR my work ASK myself, “Does this make sense?” CHANGE my plan if it isn’t working out

CHECK ! Is my answer correct? ! How do my representations connect to my solution? EVALUATE ! What worked/didn’t work? ! How was my solution similar or different from my classmates’?!

Reason abstractly and quantitatively. Mathematical Practice 2!

!

!

I can use numbers, words, and reasoning habits to help me make sense of problems.

Contextualize (Numbers to Words)

!!!x!6!=!3!!!or!!!6!x!

!!!=!3!

Mary practices the piano!!!!!!hour a day for 6 days. How many total hours does she practice?

!

Decontextualize (Words to Numbers)

Mary practices the piano !!!!!hour a day for 6 days. How many total hours does she practice?

!!!x!6!=!3!!!or!!!6!x!

!!!=!3

Reasoning Habits

1) Make an understandable representation of the problem.

3) Pay attention to the meaning of the numbers.

2) Think about the units involved. 4) Use the properties of operations or objects.

Construct viable arguments and critique the reasoning of others. Mathematical Practice 3!

!

!

I can make logical arguments and respond to the mathematical thinking of others.

I can make and present arguments by…

• using objects, drawings, diagrams and actions

• using examples and non-examples

• relating to contexts

I can analyze the reasoning of others by…

• listening

• asking and answering questions

• comparing strategies and arguments


Model with mathematics. Mathematical Practice 4

!

!

I can recognize math in everyday life and use math I know to solve problems.

I can…

…to solve everyday problems.

My box turtle is getting a new tank. He is 5 1/2" long and 3" tall. One side length of the tank needs to be 5 times his length. How long will the length of the tank need to be?

Use estimates to make the problem

simpler. I will round 5 1/2" to 6".

Find importantnumbers.

Turtle: About 6" longTank: 5 times the length of the turtle

Use tools to show relationships.

TurtleLength(inches)

TankLength(inches)

45678

2025303540

Think about the relationshipto find an answer.

Consider my answer --Does it make sense?

The tank (30") is 5 times bigger than the turtle length (6").

I thought about the problem again and a 30" side length on the tank makes sense!

Use appropriate tools strategically. Mathematical Practice 5

!

!

I can use certain tools to help me explore and deepen my math understanding.

• I know HOW and WHEN to use math tools.

• I can reason: “Did the tool I used give me an answer that makes sense?”

!


a x b = b x a

Attend to precision. Mathematical practice 6

!

!

I can be precise when solving problems and clear when communicating my ideas.

Mathematicians communicate with others using…!!!!!!!!!

• math vocabulary with clear definitions

• symbols that have meaning

• context labels

• units of measure

• calculations that are accurate and efficient

48 inches = 4 feetunits of measure

symbol: equal (the same as)

Look for and make use of structure. Mathematical Practice 7

!!

!

I can see and understand how numbers and spaces are organized and put together as parts and wholes.

Numbers For Example:

!

Equivalent!Fractions!

Spaces

For Example:

310 is equal to 30

100

310 + 4

100 = 34100

I know that

Look for and express regularity in repeated reasoning. Mathematical Practice 8

!

!

I can notice when calculations are repeated. Then, I can find more general methods and short cuts.

As I work…

There are many ways to decompose !! because it is composed of repeated !! s.

I CAN…..

…I think about what I’m trying to figure out while I pay attention to

the details

….draw a whole and shade

in three!!! s parts.

….add eighths.

!! = !! + !! + !!

….count by eighths. (one-eighth, two eighths, three eighths)

!! = !! , !! ,!!!!

…I evaluate if my results are reasonable.

….jump three !! size jumps on a number line.
