SMP 1 – Make Sense of Problems
and Persevere in Solving Them.
Learned Helplessness:
I can’t do this problem

"Too many students give up upon
encountering difficulties in math,
when just trying a few strategies
could mean the difference between
succeeding and failing."
-- Arthur E. Schwartz
Fast Processors:
This problem is wrong

"If there is a problem you can't
solve, then there is an easier
problem you can't solve: find it."
-- George Polya
SMP 1 – Make Sense of Problems
and Persevere in Solving Them.
I can solve problems
without giving up.
SMP 2 – Reason abstractly and
quantitatively.
Students move from:
tangible to intangible
with units to without
SMP 2 – Reason abstractly and
quantitatively.
I can think about
numbers in many ways.
SMP 3 – Construct viable arguments
and critique the reasoning of others.
Does the commutative
property work for
subtraction?
Johnny: Yes,
2-2=0 and 2-2=0
SMP 3 – Construct viable arguments
and critique the reasoning of others.
I can explain my
thinking and try to
understand others.
SMP 4 – Model with mathematics.
SMP 4 – Model with mathematics.
I can show my work
in many ways.
SMP 5 – Use appropriate tools
strategically.

5 * $4.97
$4.97 =$5 - 3¢
.5 * $14.70
.5 = ½
$14.70 =$14 + 70¢
SMP 5 – Use appropriate tools
strategically.
I can use math tools
and show why I
chose them.
SMP 6 – Attend to precision.
SMP 6 – Attend to precision.
I can work carefully
and check my work.
SMP 7 – Look for and make use of
structure.
1+2=3
10 + 20 = 30
.1 + .2 = .3
1/10 + 2/10 = 3/10
1/5 + 2/5 = 3/5
SMP 7 – Look for and make use of
structure.
I can use what I know
to solve new problems.
SMP 8 – Look for and express
regularity in repeated reasoning.
2+2+2+2+2+2=6x2
5 = 10 ÷ 2 so a x 5 = a x 10 ÷ 2
or a ÷ 2 x 10

11 x 23
253
SMP 8 – Look for and express
regularity in repeated reasoning.
I can discover and
use shortcuts.
