Math Lesson 10
This document contains a lesson on algebraic operations taught by Md. Abdul Quddus in the Mathematics department. The lesson covers simplifying algebraic expressions using properties like commutative, associative, and distributive properties. It also covers combining like terms. Examples are provided to demonstrate simplifying expressions using these properties and combining like terms. The learning outcomes are listed as being able to simplify equations and find solutions to quadratic equations.
Math Lesson 9
1) The document introduces Md. Abdul Quddus from the Mathematics department and outlines the learning objectives of expressing algebraic expressions and identifying variables, coefficients, and terms.
2) It defines key algebraic concepts such as variables, constants, coefficients, terms, and like terms.
3) Examples are provided to demonstrate these concepts, including completing a table to identify variables and expressions for word problems.
Math Lesson 8
This document contains a lesson on finding the area of composite figures. It includes an introduction, learning outcomes, examples of calculating areas of shaded regions within composite figures like rectangles and trapezoids, and practice problems for students to solve. The lesson aims to teach students to calculate the total area of an object by finding the individual areas of each shape within it and adding them together.

Math Lesson 7
This document is a lesson plan on measurement for a mathematics class. It introduces the topic of measurement, lists learning outcomes around solving problems involving length, area, weight and volume using different measurement systems. It also provides examples of measuring the height of a giraffe, weight of a killer whale, and amount of water to fill a tub. As homework, students are asked to solve exercises 3-4 and 3-5.
Math Lesson 4
This document provides an introduction and lesson on percentages. It includes:
- An introduction to the mathematics department and chapter on profit and loss.
- Learning outcomes which are to explain percentages and calculate basic percentages without a calculator.
- Examples of calculating 30% of Tk. 40 and 75% of Tk. 600 are shown step-by-step.
- A chart reviewing common percentages is included.
- Homework is assigned to solve two questions from exercise 2.1.
Math Lesson 5
This document is a lesson on profit and loss in mathematics that introduces key concepts and examples. It explains that profit occurs when an item is sold for more than it was bought for, while loss is when an item is sold for less. Basic profit and loss calculation formulas are provided. Two examples are given, one showing a profit and one a loss. Students are instructed to complete homework problems calculating profit and loss, including using percentages.
Math Lesson 6
This document is a lesson on simple and compound interest. It begins with an introduction and then defines the formulas for simple and compound interest. For simple interest, the formula is Interest = Principal x Rate x Time. For compound interest, the formula is Amount = Principal x (1 + Rate/Number of times compounded)^(Number of times compounded x Time). The document provides examples of calculating simple and compound interest based on investing or saving different principal amounts over various time periods at given interest rates. It concludes by assigning homework to calculate the amount of interest earned on an account over 2 years.
Math Lesson 3
This document provides a lesson on number and geometric patterns. It contains 3 key learning outcomes:
1) Students will be able to explain geometric patterns.
2) Students can solve problems involving patterns.
3) Students will draw patterns.
Examples of simple number and geometric patterns are presented, including a flower bed pattern where the number of patio stones can be described by the formula Patio stones = 3 + 7n. Students are assigned homework to solve exercises involving finding patterns and differences in sequences.
Math Lesson 2
This document is a lesson plan on geometric patterns that includes:
1) An introduction to the topic of geometric patterns and learning outcomes of being able to explain, solve problems about, and draw patterns.
2) An example pattern and questions to make a number list, draw the next figure, and find the number of sticks for a specific figure.
3) An evaluation question to find the number of sticks for the 176th pattern and draw the 5th pattern.
4) A homework assignment repeating the example questions.
Math Lesson 1
This lesson document outlines a mathematics lesson on geometric patterns. The lesson will teach students to explain geometric patterns, solve problems related to patterns, and draw patterns. Students will analyze a sample pattern figure to make a number list, draw the next figure, and determine the number of sticks for the 67th figure. For evaluation, students will find the number of sticks for the 200th pattern and draw the 5th pattern. As homework, students are assigned to solve exercise 1 questions 7 and 8.
Physics class 2
This document provides an introduction to the concepts of physical world and measurement. It defines the physical world as the reality that can be perceived by our senses, and distinguishes between the physical world and reality. It then discusses different branches of science such as physics, chemistry and biology that study the physical world using various methods of observation, experimentation and measurement. Finally, it briefly introduces the concepts of space, time and matter.
Physics class 10
This document discusses the different branches of physics and their relationship to physical quantities like space, time, and matter. It aims to help students understand the connections between physics and other fields like healthcare, agriculture, technology, social science, and astronomy. The key physical quantities discussed are space, time, and matter. Students are asked to write down their basic understanding of these physical quantities.
Physics class 8
1. The document discusses fundamental and derived units of measurement and the fundamental rules of measurement.
2. It explains that fundamental units include units of length, time, mass, and temperature while derived units are combinations of fundamental units.
3. The document outlines several systems of measurement including the CGS, FPS, MKS, and SI (metric) systems which define the fundamental standards.
Physics class 5
1. Errors in measurement include instrumental errors, observational errors, random errors, and systematic errors.
2. Instrumental errors arise from defects in measurement instruments and include zero errors, backlash errors, and level errors.
3. Observational errors are due to personal factors of the observer and conditions of observation.
4. Random errors occur unpredictably while systematic errors are due to defects in instruments or measurement methods and produce consistent bias.
5. The accurate value of a measured quantity accounts for the measurement error and can be calculated using formulas provided.
