Intent of the Standards
The intent of the standards is to provide a “focused” curriculum.
How do we make sense of teaching deeply?
Think of a swimming pool.
Cognitive Complexity
Low Complexity
Relies heavily on the recall and recognition; computation
Moderate Complexity
Involves flexible thinking and usually multiple operations; problem solving
High Complexity
Requires more abstract reasoning, planning, analysis, judgment, and creative thought; multiple representations

What are your thoughts about this activity?
Were you amazed at the outcome?
What would be the depth of knowledge for this activity? Justify your answer.
Foundational Number Concepts
Inclusion -If you ask a child to bring you 5 toy trucks and he brings you the fifth truck that he counts, he may not understand that all 5 trucks are included in the entire set of trucks. The fifth truck is only part of the set.
One-to-One Correspondence mastered the skill.
-The matching of one number to one object. Children who call numbers at a faster or slower rate than they are able to point to, may not yet have
Foundational Number Concepts
Conservation of Number -Children have acquired conservation of number when, for example, they recognize that a group of objects clustered tightly together still contains the same number of objects when spread over a larger area.
Number Sense and Relationships counting.
- Just like learning to read, learning to count requires numerous opportunities for purposeful
Give Me Five!
Table Talk Activity:
What do you know about five?
The answer is 5, what is the question?
Sets of Five
Write the number 1 on an index card Place the card on the table Place one counter above the card Write another number card that is one more than the first number Place the appropriate number of counters above that card Continue until you have sets of 1-5
Developing “Five-ness”
Read the article, “ Developing ‘Five-ness’ in Kindergarten” and highlight the meaningful points.
Discuss highlighted points with table partners.
Compare learning experiences identified in the article, with your past instructional strategies.
How does the depth of knowledge in the ‘Five ness” activities compare to the ‘Day of the Week” activity?

Word Problems: Compare
Sally has 4 apples. Jimmy has the same. How many apples does Jimmy have? Sally has 4 apples. She has 3 more than Jimmy. How many does Jimmy have now?
Game
Dot Cards 1-5 Shuffle the cards and give a set to each group.
One person takes a card, the others find a card that is fewer or more than.
Repeat so every one gets a turn.
Marilyn Burns, 2005
The standard for mathematics should be the same as the standard for reading-bringing meaning to the printed symbols. In both situations, skills and understanding must go hand in hand. The challenge is how do we help students develop meaning and make sense of what they do?” Discuss Marilyn Burns’ purpose in the statement above.
Literacy, Libraries and Learning
Why Connect Mathematics and Literature?
Mathematics and literature bring order to the world around us Math and literature classify objects Math and literature emphasize problem solving skills Math and literature involve relationships and patterns 40

Addition and Subtraction Strategies
Participants will explore … – The use of invented strategies to solve multi digit addition and subtraction problems –The use of Base 10 blocks, partial sums, and differences to solve multi-digit addition problems – The empty number line as a method to focus on place value when solving subtraction problems
Invented Strategies Overview
These strategies are personal and flexible for the students Students will solve the same problem in different ways that make sense to them “There is mounting evidence that children both in and out of school can construct methods for adding and subtracting multi-digit numbers without explicit instruction.” (Carpenter, et al., 1998, p. 4)
The Standard Algorithm

You’re not allowed to use it today
Problem 1
The two scout troops went on a field trip. There were 46 girl scouts and 38 boy scouts. How many scouts went on the trip?
– Van de Walle, 2007, p. 223
Problem 2
Sam had 46 baseball cards. He went to a card show and got some more cards for his collection. Now he has 73 cards. How many cards did Sam buy at the card show?
– Van de Walle, 2007, p. 223
Problem 3
There were 84 children on the playground. The 37 second-grade students came in first. How many children were still outside? – Van de Walle, 2007 p. 225
Problem 4
Tommy was on page 67 of his book. Then he read 58 more pages. How many pages did Tommy read in all?
– Van de Walle, 2007, p. 222
What do you think?
What are the advantages of using invented strategies?
What are the disadvantages of using invented strategies?
What depth of knowledge does this activity lead to?
Getting Students to Invent Their Own Strategies
Utilize word problems -Notice the wording involved in the previous problems Allow plenty of time Listen to different strategies Have students explain their methods Record verbal explanations for others to model Pose problems to be solved mentally
Transitioning to “New” Standard Algorithms
Using Base -10 Blocks for Addition –For each problem, one person of the pair should be the “doer” and the other person the “recorder.” –Keep a “written record” to translate what you do with the blocks into a paper-and pencil algorithm .
Base-10 Blocks as a Model
Problem 1: 27 + 58 10 10 1 1 1 1 1 1 1 + 10 10 10 10 10 1 1 1 1 1 1 1 1 Problem 2: 24 + 46 Problem 3: 17 + 34
Partial Sums
32 + 29 = (30 + 2) + (20 + 9) = (2 + 9) + (30 +20) = 11 + 50 = 61
32 +29 11 +50 61
Partial Sums: Focus on Place Value
3 2 + 29 = ( 30 + 2 ) + ( 20 + 9 ) = ( 2 + 9 ) + ( 30 + 20 ) = 11 + 50 = 61
3 2 + 29 11 +50 61
Partial Sums
+ + 3276 4785 7000 900 150 11 8061
Using Base-10 Blocks for Subtraction
Using Base-10 blocks and place-value charts to develop the traditional algorithm for subtraction.
Problem 1: 73 – 26 Problem 2: 60 – 32
Partial Differences
73 – 26 = (70 + 3) – (20 + 6) = (60 + 13) – (20 + 6)= (60 – 20) + (13 – 6)= 40 + 7 = 47
60 13 73 -26 7 + 40 47

– How does the content prepare students for more advanced mathematics?
– How do the prior activities support children to get to the depth of knowledge identified by the State (Moderate – DOK2)?
