Unit of work - column addition and subtraction - NCETM inspired PowerPoint

Each lesson follows the same maths lesson structure of:

• Revisit
• Address Misconceptions
• Vocabulary
• Focus
• Guided Practice
• Talk Task
• Deepen
• Independent Task

The ‘Independent Task’ slide has a ‘Now, Next, Last’ visual to promote children’s independence in completing their tasks.
The Powepoint is infused with STEM sentences, different representations, practical activities, fluency, and reasoning tasks.

The overall structure of the unit is inspired by the NCETM for Year 4 and some questions and representations are taken from White Rose. There is a real mixture of resources used and combined to create a comprehensive unit that can be delivered straight from this download.

The lesson objectives are as follows:

• Identify place value
• Use column addition with regrouping
• Use column addition with regrouping twice
• Use column addition with regrouping twice
• Decide on mental or written strategies
• Solve addition problems
• Identify the minuend and subtrahend
• Use column subtraction
• Use column subtraction
• Use column subtraction with one exchange
• Use column subtraction with one exchange
• Use column subtraction with one exchange
• Use column subtraction with one exchange
• Use column subtraction with two exchanges

There are multiple lessons on subtraction with one exchange as this is where I have found children struggle the most within the unit. There are multiple lessons with multiple representations and a variety of challenging questions which extend those who do grasp this concept quickly.
