Lesson Content/Board Summary

Examinations: Review and Assessment

Place Value

Place value is the value of each digit in a number based on its position. For example, in the number 528, the digit 5 is in the hundreds place, 2 is in the tens place, and 8 is in the units place.

Example: What is the place value of the digit ‘7’ in the number 734?

Solution:

• Step 1: Identify the position of the digit ‘7’. It is the first digit from the left.
• Step 2: Starting from the right, the positions are Units, Tens, Hundreds.
• Step 3: Therefore, ‘7’ is in the Hundreds place. Its value is 700.

Addition and Subtraction of Numbers

Addition is the process of combining two or more numbers to find their total sum. Subtraction is the process of finding the difference between two numbers.

Example 1 (Addition): Calculate 245 + 132.

Solution:

• Step 1: Add the units digits: 5 + 2 = 7. Write 7 in the units column.
• Step 2: Add the tens digits: 4 + 3 = 7. Write 7 in the tens column.
• Step 3: Add the hundreds digits: 2 + 1 = 3. Write 3 in the hundreds column.
• Answer: 377

Example 2 (Subtraction): Calculate 387 – 153.

Solution:

• Step 1: Subtract the units digits: 7 – 3 = 4. Write 4 in the units column.
• Step 2: Subtract the tens digits: 8 – 5 = 3. Write 3 in the tens column.
• Step 3: Subtract the hundreds digits: 3 – 1 = 2. Write 2 in the hundreds column.
• Answer: 234

Multiplication

Multiplication is a quick way of adding the same number many times. It is also known as repeated addition.

Example: Calculate 34 x 3.

Solution:

• Step 1: Multiply the units digit by 3: 4 x 3 = 12. Write down 2 and carry over 1 to the tens column.
• Step 2: Multiply the tens digit by 3: 3 x 3 = 9.
• Step 3: Add the carried-over 1 to the result: 9 + 1 = 10. Write down 10.
• Answer: 102

Simple Fractions

A fraction represents a part of a whole. It has a numerator (top number) and a denominator (bottom number). For example, 1/2 means one part out of two equal parts.

Example: What is 1/4 of 12 pencils?

Solution:

• Step 1: Divide the total number of pencils by the denominator of the fraction.
• Step 2: 12 ÷ 4 = 3.
• Step 3: Multiply the result by the numerator (which is 1): 3 x 1 = 3.
• Answer: 1/4 of 12 pencils is 3 pencils.

Measurement (Length)

Length is the distance between two points. Common units for measuring length are centimetres (cm) and metres (m).

Conversions:

• 1 metre (m) = 100 centimetres (cm)

NOTE: When converting from smaller units to larger units divide, but when converting from larger units to smaller units multiply.

Example: Convert 5 metres to centimetres.

Solution:

• Step 1: Identify the conversion factor: 1 m = 100 cm.
• Step 2: Since we are converting from a larger unit (metres) to a smaller unit (centimetres), we multiply.
• Step 3: Multiply 5 by 100: 5 x 100 = 500.
• Answer: 5 metres is equal to 500 centimetres.
