Secretary"s Message

Dear Teacher,

The Mathematics Teacher's Manual is produced for Grade 3 teachers to help and guide them to plan and teach the Mathematics lessons in line with the National Mathematics Textbook for Grade 3 students. The Textbook and Teacher's Manual were developed The Teacher's Manual is designed to achieve the implemented curriculum of the content standards outlined in the syllabus. It provides suitable teaching and learning content and concepts for the primary school teachers to promote and maintain standard lessons for The Teacher's Manual guides critical thinking and problem-solving approach in which you This Teacher's Manual introduces many new approaches for lessons with more mathematics It will help you to teach mathematics processes step by step with necessary information to new teaching approaches through careful reading and preparation of each lesson using this

Teacher's Manual.

You are encouraged to use the Teacher's Manual and Textbook with other relevant resources love mathematics. I commend this Teacher's Manual for Grade 3 Mathematics to be used with the National

Guinea.

IV The Teacher's Manual has been developed for teachers to teach learning contents to their students more effectively with the National Textbook. The features of this Teacher's Manual and its contents correspond to the National Mathematics Textbook according to Grades 3-5 Mathematics Syllabus. The standards outlined in the syllabus are reflected in this Teacher's Manual to help teachers plan and conduct lessons. The Prelimenary pages of the Teacher's Manual consists of the following 7 sections: How to Use Teacher's Manual, Lesson Presentation using TB and TM, How to use Blackboard plan, Assessment, Attachments, Yearly Overview and Mental Mathematics Skills. It is important for you to take time to read and understand how to use the Textbook and the Manual. The composition of the National Textbook consists of the following features.

The students can enjoy by filling in the boxes

with numbers where the answer equate to the page numbers. 2. Titles and Numbers

Each chapter consists of Chapter and Sub-

chapter titles with numbers. All problems in the textbook have Task and activities using numbers to indicate. We call

In order to use the Teacher's Manual effectively, it is important to understand the composition of the National Textbook.

1. How to use the Teacher's Manual

1.1 Composition of National Textbook

V "Necessary Competencies acquired through the use of textbook" Experimental mathematical activities such as "measure", "compare", "divide", "order", "touch", "pile up" and "throw" are contained in all grades. It is intended to develop the ability and skills to be able to solve various problems logically in daily life by considering many ways.

Mathematical Literacy

Activities f or improving reading, expression and comprehension abilities and skills are contained in relating f ormulas, letters and graphs. In addition, textbooks are designed in order to use acquired abilities and skills f or future learning content and daily life situations.

Structure of a Chapter in the Textbook

The structure in the Chapter consists of several Sub-Chapters, Tasks, Activities, Exercises and ends with a set of Exercise and Problems.

Exercise & Problems

Revison "Do you remember?"

Sub- Chapter

Tasks

Activities Exercise

Additional information is

placed in some units to relate the content covered to cultural and social aspects of life. It helps the students to think mathematically in solving daily life situations.

Additional Information

At the end of each chapter, Exercises are set

for students to consolidate what has been learnt in a particular chapter. Page numbers indicating specific content found for each exercise is tagged beside each exercise.

The Problems are placed after each exercise

in each chapter. The problems are more advanced in order to enhance students higher order thinking skills for each chapter. It also guides students to apply what they have learnt.

This section of the textbook is purposely

for revision. Before moving into the next chapter, these set of exercises will enable students to reflect to the contents covered in the past and relate to the new chapter. This also promotes solidifying of previous content.

Exercise

& Problems The introduction page consist of two pages which introduces very important information and icons

allowing students and teachers to be familiar with what is expected to be encounted in the textbook. It

also has chapters learned from previous grade outlined carefully and a table of contents. It promotes sequences of learning to help teachers to plan and program effectively.

Let"s remember the

additions in 2nd grade to think of how to do this.

Let"s think about how to add.

Addition of 3-digit Numbers1

For the party decoration, we made 215 paper rings

yesterday and 143 rings today.

How many paper rings

did we make altogether?

1 Write a math expression.

2 Approximately how many

paper rings is the answer?

3 Let's think about how to add three digit numbers.

Yamo's idea

Calculate the addition vertically

like the addition of 2 digit numbers. Line up place values, then put in numbers accordingly.

2+1 for the sets

of 100s. 1+4 for the sets of 10s. 5+3 for the ones.

Vertically line up the numbers

according to their place values.1+4=55+3=82+1=3quotesdbs_dbs47.pdfusesText_47
