4 Number and Number Sense
October 21, 2010 Number and Number Sense Standard: K.5 What do students have to do? Look for verbs. With what? With what parameters? Which figures, numbers, shapes? Vocabulary Essential Understandings Sharing Halves Fourths Parts Whole Set Region Equal parts Equal size Equal area Recognize Parts of a whole (sets and regions) Given a region – id Given a set - id Identify fractions Identify equal parts Understand fraction concept (equal parts – sharing) Sets Regions Concrete Halves Fourths 4 4

5 Equal Parts - SORTING Equal Parts Not equal

6

7 Recognize that fractions represent parts of equal size of a whole
K.5 Identify the parts of a set and/or a region that represents halves and fourths. Recognize that fractions represent parts of equal size of a whole

8 start taking about fair share.
Grade 1: start taking about fair share. Write the fraction

9 Why is this not cut into equal parts?
How many equal parts do you see? Which is cut into fourths? Why is this not cut into equal parts?

10 Halves and Fourths of Sets
Worksheets – circle one half, circle one fourth If no conceptual understanding – they can’t do it

11 Halves and Fourths of Sets
Count students in halves and fourths as often possible and let the students use the vocabulary words: halves and fourths Make sure they know the parts created are subsets of the whole.

12 Halves of a Set

13 Halves of a Set 6 6

14 Halves of a Set Now they know to circle 6 triangles

15 Fourths of a Set 3 3 3 3

16 (beyond the unit fractions)
Fourths of a Set (beyond the unit fractions) 3 3 Ask them to show you one-fourth, two-fourths, three-fourths, even four-fourths. 3 3

17 Equality and Properties – preparation for justifications
5.19 distributive property of multiplication over addition New from grade 7 4.16 b) associative property for add/mult Newfrom grade 7 3.20 a) identity/ commutative properties for add/mult 1.18 demonstrate equality using equal signs New from grade 3 2.22 demonstrate an understanding of equality using = and ≠ New content 6.19 a-c) investigate and identify property of +/X, multiplicative property of zero, inverse property for multiplication 7.16 a-e) apply properties with real numbers, comm/associative property of +/X, distributive, /X identity, /X inverse, X property of 0 Leading into students giving justifications to steps when solving equations and inequalities in MS and HS

18 Equations and Inequalities
Vertical Alignment Modeling one step linear equalities What does the equal sign mean?

19 Equality Where are we headed? 5 + 3 =
October 21, 2010 Equality Where are we headed? 5 + 3 = AND THE ANSWER IS…….? Now students should think about options to balance the equation on the right side. List 5 options that would make the sentence balance? 8, 10-2, 1+7, , Connected to N&NS SOL 2.1c 1.18 The student will demonstrate an understanding of equality through the use of the equal sign The student will demonstrate an understanding of equality by recognizing that the symbol = in an equation indicates equivalent quantities and the symbol ≠ indicates that quantities are not equivalent.

20 SOL 1.18 demonstrate equality using an equal sign
SOL 2.22 demonstrate understanding of equality and not equal signs

21 Equalities SOL 2.22 and SOL 3.20

22 Inequalities 2009 SOL 3.20 (C.F. - Essential Understanding )
Using the Commutative property, we can allow students more opportunities to explore equality. Representing this property in a variety of forms will provide them more opportunities to connect the characteristics of these properties to future mathematical endeavors. 2 3 4

23 Equalities 2009 SOL 3.20 (C.F. - Essential Understanding )
Commutative Property of addition Using the Commutative property, we can allow students more opportunities to explore equality. Representing this property in a variety of forms will provide them more opportunities to connect the characteristics of these properties to future mathematical endeavors. 3 4

24 Equalities/Properties 2009 SOL 4.16a
K.6 Bag of 10 dual color chips (beans), spill on the table, and sort the two colors. Count and write the number of each color. Continue until all the facts have been created. Will see the inverse when you have all 10 fact. Will build a foundation for 3+7 = 7+3 and = 4 +6 The finished list will show all the fact families for adding to the sum of 10 Red Blue Identity Property of Addition 8 + 0 = 8 Commutative Property of Addition 4 + 3 = 3 + 4 Identity Property of Multiplication 8 x 1 = 8 Commutative Property of Multiplication 2 x 5 = 5 x 2 Show the blue number balances…participants write on the smart pals….Robin makes a model, Kim make a model…Who can come up with a third?

25 What will the students say?
Equalities SOL 4.16a recognize/demonstrate meaning (thinking) of equality in an equation. What will the students say? True or False? 8 = 1 + 7 2 + 3 = 2 x 3 3 + 5 = 5 + 3 Will students agree that 8 = 1 + 7? Many times they think that it has to say = 8. Use the balance to prove that they are equal. Continue with the other equations. Discuss commutative property? How many different ways can you show 9 = 9? Can you show ? 7 x 4 = 9 = 9

26 Linear Equations 2009 SOL 5.18 a-b
P Y Investigate and describe concept of a variable. Write open sentences using a variable W Z Again, this is an equation using multiplication. This would NOT be tested in fifth grade, but could be used to differentiate for those students who are ready for that discussion. What is the value for B here? How might you write this equation? 26 26

27 Modeling One-step Linear Equations 2009 SOL 5.18c
Using a cup and candy corn, construct a model for J = 6 Again, this is an equation using multiplication. This would NOT be tested in fifth grade, but could be used to differentiate for those students who are ready for that discussion. What is the value for B here? How might you write this equation?

28 Modeling One-step Linear Equations 2009 SOL 5.18c
How many to balance? Students can discover what the unknown variable is here without having to write an equation.

29 Modeling One-step Linear Equations 2009 SOL 5.18c
Using your cups and candy corn, construct a model for J + 4 = 7 Again, this is an equation using multiplication. This would NOT be tested in fifth grade, but could be used to differentiate for those students who are ready for that discussion. What is the value for B here? How might you write this equation?

30 Modeling One-step Linear Equations 2009 SOL 5.18c
Now you try. How might you write this equation? What is the value for J here?

43 Modeling to solve word problems
October 21, 2010 Build skills to solve multi-step problems Modeling to solve word problems Tamara had 3 pennies. She got 5 pennies for cleaning her room. Then she lost 2 pennies. How many pennies does she now have? Zach had 64 ounces of soda. He poured 8 ounces into each of 5 glasses. How much soda was left over? Emily is reading the latest Magic Maggie book. She reads 12 pages each day. After 7 days, Emily still has 20 pages left to read. How many pages are in Emily's book? 43 43

44 October 21, 2010 Students need opportunities to solve various problem types through modeling, reasoning, and reflection to strengthen their mathematics understandings and use of concepts and skills. Let the students struggle, take a risk at getting it wrong, explain why, re-think, re-do! Check out this site: 44

48 We Must Provide…. A focus on content plus….
a balance between conceptual and procedural approaches. include relevant and real world applications. give students intentional vertical connections to other grade level content and practices. reflection time – to answer “the why”, “ the what if”

49 Technology Enhanced Items (TEI)
Format of Questions: Fill in the blank Click and drag Hot-spots: Select one or more answer options, placing points on coordinate planes Creation of graphs Approximately ten practice questions for each mathematics test, Grades 3-8 and EOC addressing – February 2011 increased rigor for existing SOL items that address new SOL technology enhanced items - 49 - 49

50 Mathematics Standards of Learning Implementation Timeline
2010 – 2011 Teach old and new SOL content Field Test items on new 2009 SOL – live test items on 2001 standards Grade 3 live test is still cumulative but field test items on new content is only from grade 3 content New 2009 SOL taught and fully assessed New Grade 3 assessment covers 2009 grade 3 content only Gr. 3-5 technology enhanced items are live spring 2013 - 50 -

51 They serve a vital and critical role in
PIVOTAL QUESTIONS The following questions are aligned with the Standards of Learning. They serve a vital and critical role in unveiling student understanding and misconceptions in ways that knowledge-recall questions do not allow.

52 PIVOTAL QUESTIONS 1. Can be solved or explained in a variety of ways
2. Focus on conceptual aspects of mathematics 3. Have the potential to expose student understanding and misconceptions 5. Lend themselves to a scoring rubric (see the rubric included)

53 Try to make some simple shifts in what you expect from students.
That means….asking it differently! Here are some examples of how you might adjust a few typical elementary concepts.

54 Incorporate Good Mathematical Questioning
• How did you arrive at that answer? • Why do you think that? • What have you discovered? • Have you thought of another way this could be done? • Does that make sense? • Does that always work? • How could we prove that? • Have we solved a problem similar to this one? • Is that the only possible answer? • Is your solution reasonable? • Is there a real-life situation where this could be used? • Where else would this strategy be useful? • Do you see a pattern? Is there a general rule? • What other questions does this bring up? • What is the math in this problem? • Have you tried making a guess? • Would another recording method works as well or better? • Give me another related problem. • Is there another way to draw or explain that? • How did you organize your information? • Would it help to draw a picture?

55 Try to make some simple shifts in what you expect from students.
That means….asking it differently! Find a rectangle in the classroom. What shape are the student desks? Instead ask: How do you know the chalk board is a rectangle? How do you know the student desks are not a square?

56 Try to make some simple shifts in what you expect from students.
That means….asking it differently! What is the probability of drawing a red marble from bag one? Instead ask: If you close your eyes, reach into a bag, and remove 1 marble, which bag would give you a better chance of picking a blue marble? How could we prove that? Is there a real-life situation where this could be used? 75 red 25 blue 1 40 red 20 blue 2 100 red 25 blue 3
