Learning Target


I can reach all learners, through
engaging activities, while
knowing which phase
(counting, reasoning, and
retrieval) students are in to
build basic math fact fluency.
Goal
Fluency is being misrepresented through the use of "timed-
tests". We do not want teachers focusing on how fast students
can solve a list of math problems versus developing a strong
understanding of number sense.




Teaching them will requires more than
     flash cards and timed test.
What are basic facts?


When addends or factors are

        less than 10
Facts by Grade Level
Grade CCSS Required Fluency

  K    Add/subtract within 5
  1    Add/subtract within 10
  2    Add/subtract within 20 (know from memory all sums of two one-digit numbers)
       Add/subtract within 1000
  3    Multiply/divide within 100           (know from memory all products of two one-digit numbers)

       Add/subtract within 1,000
  4    Add/subtract within 1,000,000
  5    Multi-digit multiplication
  6    Multi-digit division
       Multi-digit decimal operations
Mastery of Basic Facts
             “Fluency”
“Mastery of a basic fact means that a child
  can give a quick response (in about 3
  seconds) without resorting to non-efficient
  means, such as counting.”
From: NCTM’s Curriculum Focal Points


“Fluency with basic facts is the efficient,
  appropriate, and flexible application of
  single-digit calculations skills and is an
  essential aspect of Mathematical
  proficiency.”
From: Baroody, (2006) article from Teaching Children
   Mathematics
CCSS different from GLCEs

The CCSS takes the approach of
  understanding there are phases
  students progress through as they
  learn their basic facts.

CCSS Words: using strategies, fluency,
  know from memory
Phases
    Phase       Description

1   Counting    Modeling and/or counting to find the answer

2   Reasoning   Deriving answers using reasoning strategies
                based on known facts
3   Retrieval   Mastery: efficient production of answers




    Each phase needs to have substantial meaningful
    practice and emphasize “thinking strategies”. This
    approach allows computation and understanding to
    develop.
Time
   Meaningful practice takes time!

It takes between 2 to 4 lessons before
   most students internalize the a
   strategies discussed in class.
Addition Strategies
•   Number After rule (n+1)
•   Count on 2 or 3
•   Doubles
•   Near Doubles
     – Doubles plus 1
     – Doubles plus 2
•   Make Ten
•   Turn Around Facts
•   Zero Property
•   Nines – add ten then subtract 1
Subtraction Strategies
•   Count Back
•   Count Up – think addition
•   Doubles
•   Zero Property
•   Related Facts
Multiplication Strategies
Number    Definition
x0        Any number times zero is zero
x1        Any number times 1 is itself
x2        Doubles – skip count by 2’s – all the even numbers
x3        1. Skip count by 3’s or
          2. Double the other factor and then add
          it in one more time
x4        Double doubles
x5        Times 10, then half
x6,7,8    Many of these are found by the commutative property
Nifty     1. The tens digit of the product is one less than the
Nines        “other” factor (4x9=36)
          2. The sum of the two digits in the product is always
             nine. (9x8=72… 7+2=9)
Squares   Fun to remember
Division Strategies
• Division as Think Multiplication
• 2s,4s,8s: Use halving rule




Multiplication Fact Posters & Division Fact Posters
http://www2.carrollk12.org/instruction/elemcurric/math/tba
   sicfacts.HTM
Daily Instruction
• After initial class lessons on specific
  strategies
• Use activities to guide students
  through phase 1 and 2 and into
  phase 3
• 5 – 10 minutes a day
             Five A Day
http://www2.carrollk12.org/instruction/elemcurric/
   math/tbasicfacts.HTM
Phase 1 Activities (Counting)
  Addition/Subtraction
• Addition
  – One More Than and Two More Than with
    Dice and Spinner (Van De Walle)
  – Pick Two Numbers: Math Mountains with
    Tiny Tumblers (Singapore/Math Expression)
  – Ten Friend Game using Ten Frames
• Subtraction
  – Ten Frame Subtracting (Carroll County Schools)
    http://www2.carrollk12.org/instruction/elemcurric/math/tbasicfacts.HTM

  – Ten Partner Subtraction
  – Pick Two Numbers:Math Mountains with Tiny
    Tumblers (Singapore/Math Expression
Phase 1 Activities (Counting)
  Multiplication/Division
• Multiplication
  – Clock Facts (Van De Walle)
  – Yay For Arrays! (E is for Explore!)
  – Explore Multiplication (E is for Explore!)
• Division
  – Yay For Arrays! For Division
  – Dot Array Fact Families(Numbered
    Heads Together)
Learning Target


I can reach all learners, through
engaging activities, while
knowing which phase
(counting, reasoning, and
retrieval) students are in to
build basic math fact fluency.
Session 2
Phase 2 Activities
      Add/Sub Strategies
