Solve this… 3 ÷ 1/7

3
Perspective… A student said this… When asked to justify the solution to 3 ÷ 1/7

4
Perspective… A student said this… When asked to justify the solution to 3 ÷ 1/7 Just change the division sign to multiplication and flip the fraction after the sign. 3 ÷ 1/7 becomes 3 x 7/1. So I find 3/1 x 7/1 which is 21/1 or 21.

5
Perspective… A student said this… When asked to justify the solution to 3 ÷ 1/7 Just change the division sign to multiplication and flip the fraction after the sign. 3 ÷ 1/7 becomes 3 x 7/1. So I find 3/1 x 7/1 which is 21/1 or 21. Is this an acceptable justification?

6
Perspective… Another student said this… When asked to justify the solution to 3 ÷ 1/7 I know there are 7 groups of 1/7 in one whole. Since there are three wholes, I have 3 x 7 or 21 groups of 1/7 in 3 wholes so 3 ÷ 1/7 = 21.

Since there are three wholes, I have 3 x 7 or 21 groups of 1/7 in 3 wholes so 3 ÷ 1/7 = 21. How is this justification different and what does it have to do with the CCSSM?

8
Background of the CCSSM Published by the National Governors Association and the Council of Chief State School Officers in June 2010 Result of collaboration from 48 states Provides a focused curriculum with an emphasis on teaching for depth

9
Background of the CCSSM Minnesota adopted the CCSS in ELA/literacy only 45 States + DC have adopted the Common Core State Standards

10
Background of the CCSSM … standards must address the problem of a curriculum that is a mile wide and an inch deep. These Standards are a substantial answer to that challenge (CCSS, 2010, p. 3).

Background of the CCSSM … standards must address the problem of a curriculum that is a mile wide and an inch deep. These Standards are a substantial answer to that challenge (CCSS, 2010, p. 3). Weve already met this challenge in Florida. How can we use our momentum to take us further and deeper?

CCSSM Content Standards Wordle

14
Content Standards Standards – define what students should know and be able to do Clusters – group related standards Domains – group related clusters Critical Areas – much like our big ideas

15
Content Standards Measurement and Data K.MD Describe and compare measurable attributes. 1.Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object. 2.Directly compare two objects with a measurable attribute in common, to see which object has more of/less of the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter. Classify objects and count the number of objects in each category. 3.Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.

Background of the CCSSM The CCSSM consist of Content Standards and Standards for Mathematical Practice. The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students (CCSS, 2010, p. 6).

18
The Standards for Mathematical Practice are based on: Making Sense of the Mathematical Practices The National Council of Teachers of Mathematics (NCTM) Principles and Standards for School Mathematics (NCTM, 2000), and The National Research Councils (NRC) Adding It Up (NRC, 2001).

23
Perspective… According to a recommendation from the Center for the Study of Mathematics Curriculum (CSMC, 2010), we should lead with the Mathematical Practices. Florida is positioned well to do this.

24
Perspective… Lead with Mathematical Practices 1Implement CCSS beginning with mathematical practices, 2Revise current materials and assessments to connect to practices, and 3Develop an observational scheme for principals that supports developing mathematical practices. (CSMC, 2010)

25
The 8 Standards for Mathematical Practice: Making Sense of the Mathematical Practices 1Make sense of problems and persevere in solving them 2Reason abstractly and quantitatively 3Construct viable arguments and critique the reasoning of others 4Model with mathematics 5Use appropriate tools strategically 6Attend to precision 7Look for and make use of structure 8Look for and express regularity in repeated reasoning

26
Impact on Depth… (NGSSS) Grade 4 Big Idea 1: Develop quick recall of multiplication facts and related division facts and fluency with whole number multiplication. MA.4.A.1.2: Multiply multi-digit whole numbers through four digits fluently, demonstrating understanding of the standard algorithm, and checking for reasonableness of results, including solving real-world problems.

27
Number & Operations in Base TenNBT Use place value understanding and properties of operations to perform multi-digit arithmetic 5. Multiply multi-digit numbers using strategies based on place value and the properties of operations. Illustrate and explain the calculations by using equations, rectangular arrays, and/or area models. Domain Cluster Standard Impact on Depth… (CCSS)

Reason abstractly and quantitatively Reasoning abstractly and quantitatively often involves making sense of mathematics in real-world contexts. Word problems can provide examples of mathematics in real-world contexts. This is especially useful when the contexts are meaningful to the students. 2

How do we support this empowerment? Teachers need content knowledge for teaching mathematics to know the tasks to provide, the questions to ask, and how to assess for understanding. Teachers need content knowledge for teaching mathematics to know the tasks to provide, the questions to ask, and how to assess for understanding. Math Talk needs to be supported in the classroom.
