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.

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

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

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?

Assessment of the Facts

K-2 •Individual interviews

•Individual observation•Small Group observation

How many am I hiding?

Games, word problems

Discuss with your group what activities students would be doing in each of

these phases.

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)

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?
