Mental Strategies
! Counting on
! Making ten (e.g., 8 + 6 = 8
+ 2 + 4 = 10 + 4 = 14)
! Decomposing a number
leading to a ten (e.g., 13 – 4 =
13 – 3 – 1 = 10 – 1 = 9)
! Using the relationship
between addition and
subtraction (e.g., knowing that
8 + 4 = 12, one
knows 12 – 8 = 4)
! Creating equivalent but
easier or known sums (e.g.,
adding 6 + 7 by creating the
known
equivalent 6 + 6 + 1 = 12, 12 +
1 = 13
With tools and teacher
support, the student can
add and subtract within
10.
Progressing toward

standard
The student can fluently
add and subtract within
20 using at least one
strategy.
The student can fluently
add and subtract
equations with in and
beyond 20 using 3 or
more different
strategies.
Fluently means
accuracy, efficiency, and
flexibility. “Know from
memory” should not
focus only on timed tests
and repetitive practice,
but ample experiences
working with
manipulatives, pictures,
arrays,word problems,
and numbers to
internalize the basic
facts.
