  1. Welcome to Everyday Math Information Session about Everyday Math, Homework, Math Algorithms (What’s 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.

  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. Your child will receive a homework assignment for each lesson in every unit. Intermediate grade work is called “Study Links.” Homework

  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 child’s 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 12’s 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

  16. So what are we waiting for? Let's go have some FUN with MATH!
