Developing Fluency with the Basic Math Facts
Use relational thinking with properties and strategies to learn the Basic Math Facts
www.tie.net
Using Flashcards
Assumea = b = c = d =
www.tie.net
How do we want students to know their
Basic Facts?
Memorization vs.
Internalization
Think about it
www.tie.net
Apply the properties with understanding
• Cross off the facts on the table as you apply the properties and strategies.
www.tie.net
1- Constructing meaning
I can---• Build it• See it• Count it• Put it
together• Take it apart
www.tie.net
Constructing meaning with numbers 1-10
• +1, -1• Part-Part Whole• Anchors of 5 and 10• Visual patterns
www.tie.net
Visual Patterns- Quick Images
• ‘Instantly’ see how many
• Recognize a number pattern as a whole
• Recognize a number as having parts
www.tie.net
2- Making Number Relationships
• Connecting a quantity to numbers, symbols
• Using strategies -making a ten-doubles ,+1, -1-ten and some more• Applying properties

Develop Fluency with Word Problems

3-Working towards recall“I just know it.”
• Quick Recall of math facts• Maintenance of Facts• Use Mental Computation to
reinforce basic number combinations
www.tie.net
Playing the Games
• With a partner play one or more of the following games
• Compare, Double Compare• Five in a Row, Roll and Record• How many are Hiding, Make 10, Tens Go
Fish
www.tie.net
Strategy Card Sort
• To build number relationships, students sort cards into strategy categories.
• Individually put the addition expressions into similar categories, then check with a partner in your group.
• How can this help you remember math facts?

Sequence of learning Addition and Subtraction
Grade Investigations1st grade
• Combinations that make 10
2nd grade
• Addition combinations to 10 + 10•Practice related Subtraction combinations
3rd grade
• Subtraction combinations to 20
www.tie.net
Assessment of the Facts
K-2 •Individual interviews
•Individual observation•Small Group observation
How many am I hiding?
Games, word problems
www.tie.net
Playing the Games 10-20Play one or more of the games to
practice fact fluency with the combinations to 20.• Chips• Plus 9 or 10• War• Double it Arrays

Look for evidence of:1- Constructing Meaning2- Reasoning Strategies3-Working towards Recall
Discuss with your group what activities students would be doing in each of
these phases.

Apply the properties with understanding
• Cross off the facts on the table as you apply the properties and strategies.

Multiplication Quick Images
• ‘Instantly’ see how many
• Recognize a number pattern as a whole
• Recognize a number as having groups of, sets of
www.tie.net
Multiplication Quick Image Activity
• One person flashes a x quick image card for 3 seconds.
• How did you see it? Share with the group.• Take a quick image card and rewrite it,
using its parts.5 x 6 = (3 x 5) + (3 x 5)

Array Cards-visual image
Read- Array
Cards InInvestigations
www.tie.net
Playing the Games-Arrays
Play one or more of the array games
• Count and Compare• Missing Factors• Small Array/Big Array
www.tie.net
Sequence of Learning Grades 3-5
Grade Investigations3rd grade Multiplication combinations with
products to 504th grade Multiplication with products to 12 x 125th grade related Division combinations to 12 x
12
www.tie.net
Suggested Sequence of Learning- Multiplication• Read the Multiplication Combinations
sequence of learning.• How can this sequence support relational
thinking?• Discuss ways you have sequenced
learning the multiplication facts?
www.tie.net
Assessment of the Facts in Investigations Gr. 3-5
Group Assessments
•Addition•Subtraction•Multiplication•Division
www.tie.net
Playing the Games-Multiplications
Play one or more of the multiplication games.• How many rows, stacks, cups?• How many rows? In each row?• Circles and Stars?
www.tie.net
Students taking ownership
Students engaged together in ‘doing math’• Sharing strategies• Listening• Working collaboratively• Talking
www.tie.net
Many opportunities to PRACTICE
Day-to-day teaching of curriculum
• focused mini-lesson, numbertalks• games and activities• homework, practice pages• word problems
Make learning meaningful and engaging
