Hello Year 1. Good morning. Today is Thursday 25 th June. We are going to be learning to explain reasoning to solve problems that involve missing quantities or numbers in number sentences. .

Mental Maths Warm Up – Let’s get counting! Clap out a 2 digit number to someone. What number is it? What would 10 more be? What would 10 less be? Repeat with different numbers.

Solve the missing number! 10 + ___ = 15 ___ + 10 = 15 15 + ___ = 15 15 – 10 = ___ 15 - ___ = 10 15 - ___ = 15

Challenge… 12 + ___ = 20 20 = ___ + 12 20 = 12 + ___ 20 - ___ = 12 What do you notice?
