ICSE Class 5 Maths, Unit 2: Number Operations
From the CISCE curriculum. 4 key concepts, about 2 days of study at 20 to 30 minutes a day.
What this unit aims at
The confidence gained in using standard algorithms for operations on whole numbers leads children to use them efficiently for problem solving and in addition, subtraction, multiplication and division of common fractions, decimal fractions and integers in later classes. Using manipulatives like place-value charts, unifix cubes and base ten blocks, 10X10 number grid and number line strengthens the understanding of standard algorithms. In using manipulatives in this context, children can be encouraged to work in pairs, one working with the models and the other recording the steps. It is important that children record the steps as they model them.
Your child should be able to
- apply the understanding of place value of numbers beyond 1000 in the four operations
- divide a given number by another number (up to two digits)
- estimate sum, difference, product and quotient of numbers and verifies the same
- use standard algorithms in addition subtraction and multiplication of numbers
- divide a given number by another number (up to 2 digits) by using standard algorithm
- solve problems involving four operations addition, subtraction, multiplication and division in different real life contexts
- frame word problems based on mathematical statements involving number operations
- explain the meaning of factors, multiples prime and composite numbers
- find and displays multiples and factors of numbers using various techniques (e.g. factor tree)
- discover prime & composite number in the number sequence up to 100
Key concepts in this unit
- Standard algorithms for addition subtraction and multiplication of large numbers.
- Division of given number by another number (up to 2 digits).
- Framing and solving Problem from real life contexts involving number operations.
- Estimation of the sum, difference, product and quotient of two or more numbers.
Teach this unit at home
- A day-by-day plan from the CISCE concepts, so you know what to cover each day.
- A step-by-step script for each day, so you know what to say and ask (AI-written from the CISCE curriculum, so check it against your child's school book).
- A quiz at the end.
