Addition and Subtraction

Level: Year 2 & Year 3

Author: Anna Bock

Description:

In this activity students have an opportunity to engage in many aspects of mathematics in the context of a game such as:

• Subsitising quantities on the dice
• Estimating the total quantity collected
• Counting using efficient strategies to find the total (moving away from counting by ones)
• Adding collections to calculate how many altogether
• Comparing quantities to find the difference

This activity covers the following Australian Curriculum – Mathematics Content:

• Solve simple addition and subtraction problems using a range of efficient mental and written strategies (ACMNA030)
• Recall addition facts for single- digit numbers and related subtraction facts to develop increasingly efficient mental strategies for computation (ACMNA055)

Notes for parents:

• This game can be played many times as the totals will often be different and the focus of the mathematics can change
• A video included to help with how to play the game
