Title: Welcome to Everyday Math
1Welcome to Everyday Math
- Information Session about
- Everyday Math, Homework,
- Math Algorithms (Whats that?)
2Everyday 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.
4Math instruction includes a LOT more than it did
when we were in school
5Everyday 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
7What 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!
8Homework
- 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.
10HOW 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
11What 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.
12Partial 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
13Trade-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
14Partial-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
15Partial-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
