Oh dear! Mr G went to visit Llanrhidian Marsh to help the farmers count their sheep and birds. But when it came to taking some away to move to a new field, Mr G got stuck! He didn’t know the best way to take away and got all the numbers muddled up. Now the farmers don’t know how many are left in the marsh!
Can you help Mr G choose the best method to take away?
Should he count back?
Should he use a number line?
Should he use a part-part-whole model?
Or should he just guess (oh no!)?
Let’s explore the methods and help Mr G solve the marshy maths mystery!" 🐑🦆🌾
L.O To take away by counting back from a number.
L.O To choose and use different mental methods to take away (counting back, number line, part-part-whole).
