CGI Chapters 4-6

--> Chapter 4: Multiplication and Division Problem Types and Children's Solution Strategies

Multiplication and division problems are grouping and partioning problems. The unknown can be the amount of groups, the amount in each group, or the total. In multiplication problems, the total in unknown. In partitive division problems, the amount per group in unknown. In measurement division problems, the number of groups is unknown. Strategies for solving these problems include direct modeling, counting and adding strategies, and number fact. Number fact strategies involve numbers with common relationships.

--> Chapter 5: Beginning to Use Cognitively Guided Instruction

Cognitively guided instruction involves understanding how students think to solve problems. When using CGI it is important to engage children in the process of problem solving. Students have to be taught how to think as problem solvers. It is also important to consider what problems are being selected and their complexity. Finally, strategies used should be shared. This can help students put their thinking into words.

--> Chapter 6: Base-Ten Number Concepts

Base-ten number concepts are thinking of numbers in terms of 10s, 100s, and 1,000s or in other words collections of 10s, 100s, and 1,000s. Students will move from 10s to 1,000s as they develop understanding of the concept. Base-ten number concepts also involve the concepts of place value.

    Thanks, Darby:) Again, I wonder how you think these strategies/materials relate to your future classroom...

TA Ch. 3: Implement Tasks that Promote Reasoning and Problem Solving

Ch. 3: Implement Tasks that Promote Reasoning and Problem Solving  Summary: It is important that teachers create learning tasks that will lead their students to an understanding of the concepts. There are different levels of demand when it comes to learning tasks. There are lower-level demand and higher-level demand tasks. Lower level tasks include things such as reproducing facts or formulas. Higher level tasks are more complex and many times include multiple steps that lead to a deeper understanding. Implications for Future Teaching: It is important that I balance the tasks I give to my students. They need to be given a combination of low level and high level demand tasks. 2 Questions:  1. How do you know that your students are ready to move from low level to high level demand? 2. How can you scaffold higher level problems to make them doable for all level students?

Manipulative Activities

Manipulative Activities  When students are using manipulatives, it is important that teachers question them in ways to monitor their understanding. Teachers questions should guide students from manipulative to abstract thinking. Teachers can assess students understanding and growth through students answers to these questions. They can also assess the students ability to move away from the manipulatives after a certain period of time. When students are working in groups, students may be given roles to make sure each student is accountable for their learning. Students should rotate roles, so that each student gets to experience and practice with each role. When students are working in groups, teachers may individually question students or allow students to build off of each others answers.  Students problem solving skills are improving when using manipulatives, because you are giving them something to physically move around and work with. Anything you can make visible will help

TA Chapters 6 & 7

TA Chapters 6 & 7 Chapter 6: Use and Connect Mathematical Representations Chapter 7: Facilitate Meaningful Mathematical Discourse Summary: Chapter 6 discusses the importance of using representations such as manipulatives and drawings to model mathematical concepts. These visual tools can help students better understand what they are doing before they start solving problems more abstractly. Chapter 7 discusses the importance of the methods of teaching mathematics. One of the major discourses discussed was discussions whether these are whole class, small group, or partner discussions. Discussing concepts can help students put their ideas into words leading to a better understanding of mathematics.  Implications for Future Teaching: One of the major things I got from these two chapters is the importance of variety in instruction. While models can really help visual learners, discussions can really help auditory learners. I want to make sure I am catering to the needs o
