Teaching methods of mathematics
Group work involves students collaborating on tasks inside or outside the classroom in pairs or small teams. It aims to develop intellectual understanding, communication skills, cooperation, and independent learning. The benefits of group work include increased productivity, skills development, self-awareness, and getting to know one's self better. For group work to be effective, the purpose must be clear to members and groups should be homogeneous to ensure equal effort.
Oral work is done without writing and includes memorizing tables and doing mental math. It can save time, reduce shyness, keep students alert, test knowledge, encourage competition, and allow the teacher to remain engaged with the class. Oral work builds a strong foundation for later written work

Finally, it provides examples of dividing various quantities into different ratios.
Prime factor decomposition
This document explains how to write numbers as the product of their prime factors. It provides examples of decomposing the numbers 36 and 28 into their prime factors. To find the prime factors of a number, you think of two numbers that multiply to the given number. If those numbers are prime, they are the prime factors. If not, you continue decomposing the non-prime numbers into more prime factors until only prime numbers remain. For example, 36 decomposes to 2 x 2 x 3 x 3 = 22 x 32 and 28 decomposes to 2 x 2 x 7 = 22 x 7.
Nth term
The document provides steps to find the nth rule for a linear sequence. It uses the sequence 5, 8, 11, 14, 17 to:
1) Make a table with the terms and their position (n).
2) Find the difference between consecutive terms is 3.
3) Write this difference multiplied by n in another column.
4) The difference between this value and the term is a constant 2.
5) Therefore, the nth rule for this sequence is Term = 3n + 2.
Multiply and divide numbers between 0 and 1
Multiplication and division with numbers between 0 and 1 were investigated. A chart was created showing the results of multiplying and dividing the number 5 by various fractions between 0 and 1. The chart illustrates that as the multiplying/dividing number decreases between 0 and 1, the answer to the multiplication decreases and the answer to the division increases, with the smallest multiplying/dividing number of 0.1 resulting in an answer of 0.5 for multiplication and 50 for division.
Linera sequence
This document provides an example of finding the rule for a linear sequence, where each term is found by adding a constant to the previous term. It shows working through an example sequence where the terms are 5, 8, 11, 14, 17 etc and each term is 3 greater than the previous term. It demonstrates setting up a table with the term position (n) and values, finding the difference between terms, and the rule that the nth term is given by the expression Term = 3n + 2.
Fractions
- Pupils will review fractions from previous lessons and learn how to add, subtract, multiply, and divide fractions.
- They will complete exercises practicing these fraction operations, including changing fractions to percentages or mixed numbers, finding lowest common multiples, and solving multi-step fraction word problems.
- The lesson aims to build pupils' skills and understanding of the key fraction operations through hands-on practice problems.
Expanding two brackets
The document discusses expanding and simplifying expressions within brackets. It provides examples of multiplying out terms within brackets for expressions like (2a + 3)(4a + 2) and (3b + 2)(4b - 6). The key steps are to multiply out each corresponding term, then collect like terms. Distributing negatives requires being careful about the signs of multiplied terms. The document encourages practicing expanding several example expressions within time limits to check understanding.
Expanding over a single term
This document provides examples for expanding brackets over single terms. It shows how to expand 2(x + 4) by distributing the 2 to both the x and 4 terms, resulting in 2x + 8. A second example expands 4(2a - 3) in the same way, distributing the 4 to both the 2a and -3 terms, giving the expression 8a - 12. The key step shown is using distribution to expand brackets over single terms inside the bracket.
Expand brackets 5
This document provides steps for expanding bracketed expressions by distributing terms within the brackets. It works through expanding the expression (x + 4)(x + 2) as an example, showing that it can be written as x2 + 6x + 8 by first distributing x and 4 across (x + 2), then combining like terms. The process is demonstrated over multiple lines to clearly show each step of distributing terms and combining like terms to arrive at the final expanded expression.
Expand brackets 4
This document provides instructions for expanding brackets in algebraic expressions by distributing terms within brackets across multiplication or division. It explains how to expand expressions with one or more terms in brackets, like 3(x + 2), by treating each bracket as a single term and distributing numerical coefficients and variables before each bracket across the terms within. Examples are provided and steps are explained carefully, emphasizing distributing negative terms correctly.
Directed numbers
The document introduces how to add and subtract directed numbers on a number line. It explains that if the directed numbers have the same sign, you add their values, and if they have different signs, you subtract. It provides examples of adding 6 + -3 and subtracting -4 - -9, illustrating starting at the first number on the number line and moving the corresponding number of places based on the operation and second number. The answer is found by labeling the final location.
Expand brackets 1
To expand expressions with brackets, you multiply the terms within the brackets by the number outside. For example, to expand 3(x + 2), you multiply x + 2 by 3, giving 3x + 6. Similarly, to expand 4(2x - 3), you multiply 2x - 3 by 4, giving 8x - 12. In both cases, this removes the brackets by distributing the number outside the brackets to each term inside.
Expand brackets 3
The document explains how to expand brackets in algebraic expressions by distributing any terms outside the brackets to the terms inside. It provides examples of expanding brackets in expressions like 3(x + 2), (x + 3)(x - 2), and x(x + 4) + 3(x + 2). The final expression x^2 + 7x + 6 is reached by first distributing x and 3 to the terms inside their respective brackets, then combining like terms.
Sequences
The document discusses sequences and their rules. A sequence is a list of numbers with a connecting rule. Examples are given such as adding 4 to get the next number. Linear sequences are defined as having a constant difference between terms. An example linear sequence is shown as adding 3 each time to get the next term. A method is provided to find the nth term rule, which involves making a table and finding the difference is a constant amount added each time.
Decimal places
The document provides instructions for rounding numbers to a specified number of decimal places. It explains that to round to one decimal place, you identify the digit in the first decimal place and increase the digit if the following digit is 5 or greater. Examples are provided rounding numbers to one, two, and three decimal places to demonstrate the technique.
