We are starting a new unit in Math on Addition and Subtraction to 18. In this unit, your child will be developing strategies for adding and subtracting 1-digit numbers.
We will be focusing on:
• Developing and using mental math strategies to add and
subtract two 1-digit numbers, including zero.
• Looking for patterns in digits when adding and subtracting.
• Understanding and using the relationship between addition
and subtraction; for example, 2 + 7 = 9 and 9 – 7 = 2
• Finding out if 2 sides of a number sentence are equal or not equal; for example, 10 = 6 + 4 and 3 + 6 ≠ 10
