Strategies to Help with Math Fluency


Developing Fact Fluency and Quick Recall of Basic Facts is

very similar to being on a successful dieting program.

In order to lose weight, you need to eat healthy,

exercise regularly and

assess your progress through weighing yourself on the scale.

The same is true for developing fact fluency!

Extensive amount of time needs to be spent working with and

applying basic fact strategies, as well as reasoning and

mental strategies.

In order to determine the effectiveness,

assessment plays a key role.

In contrast, assessing continuously

without more time spent developing strategies is ineffective.

That is like a person who knows about the dieting program,

doesn’t eat healthy or exercise,

but constantly weighs themselves and

wonders why they are not losing weight.


Let’s Warm Up!

D =       

E =      

Basic Fact MemorizationWhat Does Research Show?

  • Children who have a strong conceptual understanding of addition, subtraction, multiplication and division are more successful at memorizing their facts.

  • When children have a firm conceptual foundation and can use fact strategies, memorizing facts becomes a matter of efficiency.


What does the research say?

Learning with understanding is more powerful than simply memorizing because the act of organizing improves retention and promotes fluency.EDThoughts 2001 p. 81


Building Number Concepts

Abstract Symbols

*Significant time must be spent

working with concrete materials

and constructing pictorial representations

in order for abstract symbol and operational understanding to occur.


The National Council of Teachers of Mathematics (NCTM)

A mastery of lower-order skills instills confidence in students and facilitates higher-order thinking. The ability to automatically recall facts strengthens mathematical ability, mental mathematics, and higher-order mathematical learning. Without this automation, students have difficulty performing advanced operations.

Use The Five Frame!

Allows children to see relationships to 5!


“Make your five frame show three.”

The Five Frame


“We have three. How many more do we need to make five?”

The Five Frame

“Two more.”


Use two different colors to represent the addends.

“Remove two!”

“How many are left?”

Use The Ten Frame

Allows children to see relationships to 10!


Ten Frame Flash Cards

“Make your ten frame show seven.”


Ten Frame Flash Cards

“Our ten frame is showing seven.

How many more do we need to have ten?”


“We have six. Show three more than six.”

Addition Strategies

*Counting On

*Doubles

*Doubles Plus One

*Making Ten

*Making Multiples of Ten

*Front End Addition

*Zero’s & Ones

*Two’s

*Doubles

*Doubles Plus or Minus One

*Making Tens

*Nine’s

*Left over Three’s & Four’s

*Left over Five’s & Sixes


0’s

Nothing to something –answer is the other the addend

1’s

-Counting On

-One More

2’s

-Skip Counting

-Other addend is even than the answer is odd…vice versa

(2+3 the other addend is 3 so the answer will be odd)

-Count on


Doubles

*Count by 2’s

*All answers even

Doubles Plus One

Use your doubles, and add one. Use the lowest addend.

5

+6

Think

5+5=10

10+1=11

Doubles Minus One

Use your doubles, and subtract one. Use the highest addend.

5

+6

Think

6+6=12

12-1=11


Making Ten

*Combo’s of Ten/Show me Ten

Using ten frames

*Communitive Properties

*Decomposing an addend to create combos that equal ten

7+8=(5+2)+8 so 5+(2+8) = 5+10=15


9’s

9+5=14

(make a ten, add the extra)

3’s&4’s

Strategies To Support Fact Learning

Write Fact Families!

(3, 8, 11)

3 + 8 = 1111 - 8 = 3

8 + 3 = 1111 - 3 = 8


MultiplicationStrategies

*Skip Counting Songs & Chants

*Repeated Addition

*Draw Pictures

*Explore Patterns

*Arrays

*Factors & Product

*Hints & Tricks


Skip Counting Songs

  • I would teach these throughout the year during

  • Calendar

  • Review all “skip counting” the month before I

  • started teaching Multiplication (had them pass

  • each COUNT BY off)

  • Songs are in your folder and on my blog!


Building Numbers

Use Concrete Manipulatives

“Show Me”

3 x 4


Repeated Addition


Rectangle Collages(Give children grid paper to cut.)

What fact is shown?

What is the area of each rectangle?


5 x 3 = 15

Have children draw arrays to show facts!


Fact PostersChildren make a poster that shows a fact 3 different ways.

3 x 6 = 18

DivisionStrategies

I taught division

right along with multiplication

showing the Fact Family


Dividing By 3

Fair Share


Make Connections Between Multiplication and Division

What facts do you see?

3 x 5 = 15

15  3 = 5


What does the research say?

Teachers and parents should help children recognize that solving one kind of problem is related to solving another kind.Principles and Standards for School Mathematics, NCTM 2000


Fact Families Strategy - Can be used with all division facts.

6 x 3 = 18

3 x 6 = 18

18  6 = 3

18  3 = 6

18

3

6


Strategies To Support Fact Learning

Write Fact Families!

(3, 9, 27)

3 x 9 = 2727 /9 = 3

9 x 3 = 2727 /3 = 9


Halves Strategy - Use halves to find quotients when dividing by 4, 6 or 8. First halve the dividend and the divisor. Then find the quotient of the smaller fact.

24  8 = 48  6 =

12  4 = 324  3 = 8

8


Show and discuss patterns!

72 / 9 = 8……………..(7+1=8)

63 / 9 = 7……………..(6+1=7)

54 / 9 = 6……………..(5+1=6)

45 / 9 = 5……………..(4+1=5)

When dividing by 9, just add 1 to the first digit of the dividend!


Use Correct Vocabulary

  • Addend

  • Minuend

  • Subtrahend

  • Factor

  • Product


Games

Use IF…Then Charts to show:

15 /3 = 5 15 / 5 = 3

12 - 7 = 5 12 - 5 = 7


Strategies To Support Fact Learning

Use Seesaws to show Balance!

7 + 3 = 5 + ?


Play Fact Games That Include All Students

“Let’s Play

Pig!”


Cross Out

  • Cross Out Board

  • Dice

  • Beans or some kind of Marker

    Taking turns rolling the dice…Player either adds, subtracts or multiplies the 2 dice. Use the counter, covers the sum, or product on the board. Play continues until the board is covered. If they roll the same number, turn is skipped.


WAR

  • Deck of Cards

    Split the deck in half between 2 players.

    Both players turn 2 cards over. The player with the higher sum or product is the winner and collects the cards. They can either add or mulitply to get the largest answer. Other than that twist, it is played just as regular WAR.
