Welcome to Everyday Math

Welcome to Everyday Math

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

2
Everyday Math Rationale

• A research-based program Norman adopted for all
  elementary schools.
• Significant increase in 2006-2007 test scores.
• Fifth graders-89 passed, 39 advanced
• Fourth Graders-97 passed, 26 advanced
• Third Graders-98 passed, 51 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.

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.
• 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
• (multiplication and division in the fifth
  grade)
• 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
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

13
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
14
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

15
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
