8 Number Sense Number sense involves deep and fundamental understandings of, and proficiency with, counting, numbers, and operations as well as an understanding of number systems and their structures.

9 Competency Student understands that a given whole number may be represented in a variety of ways (to 100). When students are representing numbers in a variety of ways, they demonstrate their understanding of the use of number, how a number compares to another number, how a number can be broken into parts, and place value knowledge. The ability to represent numbers in a variety of ways will help students with operations and mental math.

The ability to represent numbers in a variety of ways will help students with operations and mental math.

10 Vocabulary Part-part-whole: The ability to conceptualize a number as being composed of other numbers. Concretely: Representing a situation or solving a problem using actual objects. Pictorially: Representing a situation or solving a problem using drawings or representations of actual objects. Symbolically: Representing a situation or solving a problem using an abstract representation. Most symbolic representations involves using numbers.

11 Representations Students need to be encouraged to represent numbers in a variety of ways (ie. Using manipulatives, words and pictures, number sentences, place value, money, ten frames, number line, connections to other strands and real life situations). Representations of numbers: Pictorial Part-part-whole using multiples of ten (ie. 85 = 80 + 5 or 40 + 40 + 5) Part-part-whole using non-multiples of ten (85 = 83 + 2) Regular place value (56 is 5 tens, 6 units) Irregular place value (56 is 4 tens, 16 units) Concrete with more than one type of manipulative (e.g., 36 can be represented with money, a model for tens, blocks, straws, etc.) Words Naming a number less than Naming a number greater than Odd or even Connections to real life situations Connections to other strands Story problem Another language Students need to be encouraged to represent numbers in a variety of ways (ie.

20 What are math strategies? Mental Math – Computations done by students “in their head” either in whole or in part. Strategy – A method or system of steps used to solve problems. Students must learn to make use of relationships between numbers and Operations to develop flexible math strategies.

21 Teaching Strategies The MB curriculum has identified some strategies such as making ten, starting from known doubles and doubling. However, students will use different approaches to mental calculations. The development of a variety of strategies is greatly enhanced by the sharing and discussion of solutions. The student should be given the freedom to adapt, combine, even invent strategies by providing students with good problems to solve. The aim of mental math is help students achieve fluency so they can solve more difficult calculations.

27 Venn Diagram Have students sort a set of math facts using a Venn Diagram. Observe how students arrange the set and if they apply the strategy correctly. Counting back Starting from a known double Using addition to subtract Subtract Zero

28 Strategy Cards Write the question on the front of the card then laminate the card. Student can use white board markers to record on the back of the flash card their answer and the strategy that they used to solve the problem.

29 Strategy Cards 8 + 5 = I use a known fact. I know that 8 + 4 is 12. 8 + 5 is one more than 8 + 4 so 8 + 5 would be one more which would be 13.

30 Strategy Cards The cards should be large enough to allow for students to record their strategy. As students work with the cards, they discover that there are number of successful strategies to choose from. The connections between these strategies will strengthen their understanding of the operations.

33 Operation Cards Each player needs a game board. The game board is the numbers 1 to 18. The object of the game is to be the first player to cross off all the numbers on his or her game board. The cards are placed facedown in a pile. Each player takes a turn and turns over the top two cards. The player can make either an addition or subtraction problem with the cards. The player decides on the operation to use, and marks off the answer to the problem on their game board. Note: A player may not be able to cross off a number on every turn so therefore he or she looses a turn. When all the cards in the pile have been used, a player shuffles the cards and they are used again. Each player needs a game board. The game board is the numbers 1 to 18.

38 Vocabulary Repeating pattern: A pattern that has a repeated sequence or arrangement about which predictions can be made. Core: The shortest string of elements that repeats in repeating pattern (e.g., in the pattern ABCABCABC…, ABC is the core). Increasing pattern: A pattern in which one or more elements of the sequence or arrangement increases. Term: An individual element in a pattern. Element: One of the objects or numbers belonging in a pattern. Repeating pattern: A pattern that has a repeated sequence or arrangement about which predictions can be made.

39 Group Work: Turn to your shoulder partner and explain how you would describe this pattern.

40 “This is a repeating pattern.” “The core (the part that repeats) of the pattern is circle, triangle, square.” “Every third shape is a square.” “If I start at a circle and I add three elements (shapes, …) I notice that I land on a circle” “If I start at a triangle and I add three elements (shapes, …) I notice that I land on a triangle.” “If I start at a square and I add three elements (shapes, …) I notice that I land on a square.” “This is a repeating pattern.” “The core (the part that repeats) of the pattern is circle, triangle, square.” “Every third shape is a square.” “If I start at a circle and I add three elements (shapes, …) I notice that I land on a circle” “If I start at a triangle and I add three elements (shapes, …) I notice that I land on a triangle.” “If I start at a square and I add three elements (shapes, …) I notice that I land on a square.” 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Group Work: Turn to your shoulder partner and explain how you would describe this pattern.

41 Assessment Strategies and Observation Tips When presenting repeating patterns, always repeat the core at least three times. To encourage students to make connections with numbers, present the numerical term position with the pattern. Guide students to try out their strategies with different patterns to see if it is a strategy that can be generalized or one that is specific to a particular pattern.

44 Assessment Question If this pattern continues, what will the 50th bead be? Explain or show your thinking.

45 Look For the use of an efficient strategy (using the ‘fiveness’ of the core and skip counting, grouping into tens and counting, etc.) the correct use of mathematical language related to patterns the use of an efficient strategy (using the ‘fiveness’ of the core and skip counting, grouping into tens and counting, etc.) the correct use of mathematical language related to patterns

46 Learning Experience Prepare a large number line with the numbers 1 to 30. Place the number line on the floor or on a table. Use pattern bocks to make a repeating pattern with a two element core. Place each pattern block above a number on the number line. Example: 1 2 3 4 5 6 7 8 9 10 11 12 13 14... 30

47 Questions to Ask “Can you describe the pattern?” “What part of the pattern repeats? What is the pattern core?” “What will the next shape be? How do you know?” “If this pattern continues, what shape will be above the number 10? How do you know?” “What shape will be above the number 15? How do you know?” “If we read all of the numbers that have a hexagon above them, what do we know about these numbers?” (example: They are even numbers. They are counting by 2s.) “If we continue the pattern up to the number 20, how many squares will there be altogether?” “Can you describe the pattern?” “What part of the pattern repeats? What is the pattern core?” “What will the next shape be? How do you know?” “If this pattern continues, what shape will be above the number 10? How do you know?” “What shape will be above the number 15?

48 Competency Student understands that the equal symbol represents an equality of the terms found on either side of the symbol. Understanding the equal symbol (=) means the quantity on the left is the same as the quantity on the right. Student understands that the equal symbol represents an equality of the terms found on either side of the symbol. Understanding the equal symbol (=) means the quantity on the left is the same as the quantity on the right.

49 Vocabulary Equality: A mathematical statement indicating that two quantities (or expressions) are in balance; Two expressions that are equivalent (e.g., 2 + 1 + 5 = 4 + 4) Equation: A mathematical sentence stating that two expressions are equal. An equation contains an equals sign (=). Expressions: A mathematical representation containing numbers, variable, and/or operation symbols; an expression does not include a relational symbol (=,=).

50 Equality and Inequality Why are they equal? 16 + 18 = 18 + 16 13 + 9 = 15 + 7 Why are they equal? 16 + 18 = 18 + 16 13 + 9 = 15 + 7

51 Equalities and Inequalities Essential Questions: 1.How do you know the sets are equal? 2.How do you know the set are not equal? 3.How is a number sentence like a balance scale? Essential Questions: 1.How do you know the sets are equal? 2.How do you know the set are not equal? 3.How is a number sentence like a balance scale?

52 Balance Scale Students need to be provided with opportunities to describe equality and inequality, both concretely and pictorially. Place 12 cubes onto a one side and ask students how to make the sets equal. You may have to start with small sets of numbers and then onward to larger quantities.

54 Using the Balance Scale Students need to be provided with opportunities to describe equality and inequality, both concretely and pictorially. When using the balance scale to illustrate equalities and inequalities the objects, (bingo chips, stars unfix cubes, teddy bears) must always be uniform in size, shape and mass. The color of the objects can vary and will not be a factor in determining the equality. http://illuminations.nctm.org/ActivityDetail.aspx?id=26 Students need to be provided with opportunities to describe equality and inequality, both concretely and pictorially.

55 2 cylinders + 1 triangle ≠ 1 triangle + 3 cylinders Balancing the Scale - Possible responses: There is one more cylinder on the right side. To make the scale balance, one cylinder must be taken away on the right side. There is 1 less cylinder on the left hand side. To make the scale balance, we need to add a cylinder on the left side.

56 True/False Number Sentences Asking students to choose whether each number sentence is true or false can encourage them to examine their assumptions about the equal sign. a. 3 + 5 = 8 b.8 = 3 + 5 c.8 = 8 d.3 + 5 = 3 + 5 e.3 + 5 = 5 + 3 f.3 + 5 = 4 + 4 Think Mathematically Integrating Arithmetic and Algebra in Elementary School Asking students to choose whether each number sentence is true or false can encourage them to examine their assumptions about the equal sign. a. 3 + 5 = 8 b.8 = 3 + 5 c.8 = 8 d.3 + 5 = 3 + 5 e.3 + 5 = 5 + 3 f.3 + 5 = 4 + 4 Think Mathematically Integrating Arithmetic and Algebra in Elementary School

57 Learning Experience Equal or Not Equal – Group the class into small groups. Each group needs a balance scale and a set of number sentences/equations. Have each group use the balance scale and a set of cube or counters to determine whether the number sentences are equal or not equal. 2 + 9 11 10 4 + 6 12 + 4 13 + 2 9 9 7 5 + 3 6 + 8 5 + 9 Equal or Not Equal – Group the class into small groups.

64 Literature Equal Shmequal by Virgina Kroll The story begins with a group of animals attempting to make equal teams for a tug-o-war. The meaning of the word “equal” is discussed. The animals explore using equal numbers for the teams and later use a seesaw to look at equal weight. The story provides the basis for a discussion about using objects of the same size and mass when using a balance scale to explore equality and inequality. Show this using pictures and equations.

68 Assessment is a Human Process “ It is worth noting, right from the start, that assessment is a human process, conducted by and with human beings, and subject inevitable to the frailties of human judgment. However crisp and objective we might try to make it, and however neatly quantifiable may be our ‘ results, ’ assessment is closer to an art than a science. It is, after all, an exercise in human communication. ” (Ruth Sutton, Assessment: A framework for teachers, 1992) “ It is worth noting, right from the start, that assessment is a human process, conducted by and with human beings, and subject inevitable to the frailties of human judgment.
