Students will learn to select and apply effective strategies and incorporate reasoning when offering solutions to problems involving additive thinking.
- MA3-1WM describes and represents mathematical situations in a variety of ways using mathematical terminology and some conventions
- MA3-2WM selects and applies appropriate problem-solving strategies, including the use of digital technologies, in undertaking investigations
- MA3-3WM gives a valid reason for supporting one possible solution over another
- MA3-5NA selects and applies appropriate strategies for addition and subtraction with counting numbers of any size
National Numeracy Learning Progression

Task 1: What do you notice and wonder?
Students solve number problems using flexible strategies (2 activities).
Task 2: Addition wheel
Students use an addition wheel to develop a variety of strategies to solve number problems (4 activities).
Task 3: Target number
Students try to record as many different equations (number sentences) that have a specified target number as the total (3 activities).
Task 4: Finding numbers
Students use their knowledge of additive strategies to develop alternative equations (number sentences) (one activity).
Task 5: Closest to 100
Students to use a range of additive thinking to reach the number 100 (3 activities).
Task 6: Dicey addition
Students use understanding of place value to create number sentences where the closest to 100 wins (4 activities).
Task 7: Four strikes and you’re out!
Students use a mathematical version of ‘Hangman' to think and reason numerically to solve a problem (2 activities).
