Addition and Subtraction Set e-Copy

Level 1 Addition and Subtraction covers the Addition and Subtraction only learning intentions from the Linear Series for children aged about 5 to 7 years old.

 

At this level, students are working at solidifying their facts to 10 and 20 and starting to understand place value (the value of digits in a number). They are learning their doubles and halves to 20 and are beginning to learn simple strategies for mental addition and subtraction. 

 

The learning intentions covered in this book are:

• Able to recall addition and subtraction facts to 10
• Able to recall doubles and halves to 20
• Able to count on and back in tens from any number
• Able to solve number problems using compatibles to 10
• Knows the number of tens and ones in any 2-digit number
• Able to use doubles to solve addition and subtraction to 20
• Able to work with tens Knows number facts to 20

Level 2 Addition and Subtraction covers the Addition and Subtraction only learning intentions from the Linear Series for children aged about 7 to 9 years old.

 

At this level, students are able to estimate reasonable answers to more difficult addition and subtraction equations, and they are becoming aware of the mental strategies needed to quickly compute equations with 2-digit numbers. 

 

The learning intentions covered in this book are:

• Able to estimate using known number facts
• Able to add and subtract 9 using 10
• Able to add a single-digit to a double-digit number using the part/whole method
• Able to subtract a single-digit from a double-digit number using the part/whole method
• Able to use doubles of teen numbers to solve addition and subtraction
• Able to use standard partitioning to add 2-digit numbers
• Able to use tidy numbers to add 2-digit numbers
• Able to use compensation to add 2-digit numbers
• Able to use difference to subtract 2-digit numbers
• Able to use standard partitioning to subtract 2-digit numbers

 

Level 3 Addition and Subtraction covers the Addition and Subtraction only learning intentions from the Linear Series for children aged about 9 to 11 years old.

 

At this level, students are able to use mental strategies for addition and subtraction with 2-digits numbers. This is extended to 3-digit numbers in this book and we introduce the standard written method for addition and subtraction, also. Students are now able to select from the range of strategies they know, to solve problems efficiently.

 

The learning intentions covered in this book are:

• Able to use compensation to add 3-digit numbers
• Able to use tidy numbers to add 3-digit numbers
• Able to use standard partitioning to add 3-digit numbers
• Able to use difference to subtract 3-digit numbers
• Able to use standard partitioning to subtract 3-digit numbers
• Able to use the standard written method for addition
• Able to use the standard written method for subtraction
• Able to select from a range of strategies, including the standard written method

The Linear Series (Books 1-20) cover ALL learning intentions in the curriculum. They start at Year 0 (Book 1) and continue to Year 6 (Stage 6). The Linear Series books are recommended if you wish to support your child through the mathematics curriculum as they grow.

The Subject Area books (addition and subtraction, multiplication and fractions) are collections of the material taken from the Linear Series (Books 1-20). The Subject Area books cover only learning intentions that are relevant to that book. The Subject Area books are recommended if your child has a particular difficulty in one area, like fractions.
