Boost speed and accuracy with our Addition & Subtraction to 20: Fast Facts Look & Write PowerPoint. This interactive resource helps students practise both addition and subtraction facts to 20 - supporting number fluency, strategy application and mental maths development.

Each slide features a set of addition and subtraction sums for students to solve. They write their answers on mini whiteboards or use the included printable recording sheet. After completing the facts, the answers are revealed for students to check their work. A disappearing bar timer adds an optional time challenge for extra engagement and fluency building.

Addition & Subtraction to 20: Fast Facts Look & Write PowerPoint includes two versions - one with a 2-minute countdown timer and one without. The timer bar gradually disappears, helping students manage their time visually. An editable slide is also provided for creating your own fact sets, and a PDF guide is included to help you customise the timer duration to suit your class.
