Welcome to Trumans Parent Night

• Information about
• Everyday Math, Homework,
• Math Algorithms (Whats that?)

2
Everyday Math Rationale

• A research-based program Norman adopted for all
  elementary schools.
• Excellent results on 2007-2008 test scores!
• Fifth graders-94 passed, 45 advanced
• Fourth Graders-90 passed, 37 advanced
• Third Graders-89 passed, 23 advanced
• Rigorous math instruction is the focus, leading
  students to deepen their math knowledge.

3
Everyday Math

• Students will
• discuss math strategies,
• write about math activities,
• practice math through challenging games,
• use math materials in meaningful ways to solve
  problems,
• understand measurement, geometry, probability,
  estimation,
• accurately memorize understand basic facts,
• organize data,
• develop money-smarts,
• and reason logically.

4

Math instruction includes a LOT more than it did
when we were in school
5
Everyday Math uses a spiraling instructional
model.

• Learning goals link from the past to the future.
  
• Students show beginning, developing, and secure
  skills on math concepts.
• The spiral may take two to three years for
  mastery to be achieved.
• Concepts are consistently reviewed throughout the
  model.

6

• Learning goals are based on six math strands of
  knowledge.
• Operations Computation
• Numeration
• Patterns, Functions
• Algebra
• Data Probability
• Measurement
• Geometry

7
What about homework?

• When each unit begins, a parent information
  letter is sent home explaining math ideas for the
  unit.
• Shhh!
• (It has all homework answers for the unit.)
• KEEP THIS LETTER IN A SAFE PLACE!

8
Homework

• Your child will receive a homework assignment for
  each lesson in every unit.
• Primary grade work is called Home Links and
  intermediate grade work is called Study Links.

9
More Homework Info

• Everyday Math work may seem very different than
  math we did when we were in school.
• If you and/or your child do not understand the
  homework, write a note to the teacher and help
  will be provided.
• We expect and respect parent questions.

10
HOW CAN I HELP AT HOME?

• Help your child memorize math facts
• (addition and subtraction in first and second
  grades, multiplication and division in third and
  fourth grades)
• Play Math Games
• Ask questions of both your child and your childs
  teacher

11
What in the world is an algorithm?

• Algorithms are steps used in solving a math
  question. You learned them as a child when doing
  addition, subtraction, multiplication, and
  division. Most of us learned one way to solve
  problems.
• Everyday Math has one focus algorithm for each
  math operation but a variety of methods are
  explained so students can choose the one they
  like best.
• Having lots of ways to figure out math questions
  is like having lots of tools in your toolbox.

12
Building Understanding for Math Algorithms

• Children in pre-k, k, and beginning 1st grade
  spend lots of time developing number sense.
• They play with numbers, look for shortcuts to get
  from one number to another, mentally see and move
  numbers, find math solutions for everyday
  situations, and share their own math thinking
  strategies.
• Teachers model thinking-out-loud and students
  share their own ideas and discoveries in math.
• Number sense experiences guide young children to
  think of solutions to math questions. They are
  creating their own algorithms, and then
• a variety of algorithms are introduced.

13
Partial Sums Addition

• Add one place-value column at a time.
• Write each partial sum below the problem.
• Then add all partial sums to find the total.
• 835
• 243
• (800 200) 1,000
• (30 40) 70
• (5 3) 8
• Add partial sums 1,078

14
Trade-First Algorithm for Subtraction

• Look at the numbers in each place-value column.
• Trade until the top number in each column is at
  least as large as the bottom number.
• Then subtract the numbers in each column to find
  the difference.

738 - 452
6 13 7 3 8 - 4 5 2
6 13 7 3 8 - 4 5 2 2 8 6
15
Partial-Products Algorithm for Multiplication

• Multiply each digit in the bottom factor by each
  digit in the top factor. Then add all of the
  partial products to find the total product.
• 100s 10s 1s
• 2 4 5
• 9
• Multiply 9 x 200 1 8 0
  0
• Multiply 9 x 40 3 6
  0
• Multiply 9 x 5
  4 5
• 2, 2 0 5

16
Partial-Quotients Algorithm for Division
Partial-Quotients Algorithm for Division
Example 238 divided by 12
How many 12s are in 238? (At least 10 as 10 x 12
120.) Subtract 120 from 238. How many 12s are
in 118? (9 as 9 x 12 108) Subtract 108 from
118. The difference is the remainder (as it is
less than 12.) Add the partial quotients to find
the quotient. The answer is 19, R10.

• 238
• - 120 10
• 118
• - 108 9
• 10 19
• Remainder Quotient
