Week Two - Turei 27th April

Today we looked at changing words into algebraic expressions, which basically means writing words as algebra.

To do this we need to be aware of different ways of saying plus, minus, times and divide.

e.g. plus, add, more, sum, extra, additional, increase

e.g. minus, subtract, difference, less, decrease, reduce

e.g. times, multiply, "of" (like groups of or lots of), double/twice (only for x2)

e.g. divide, split, share, halve (only for division by 2)

We then need to work out what the words would mean in terms of the symbols and numbers.

e.g. I have $p in my bank. What would I have if I:

• spent $12 ---> this would give p - 12 as the money has left the account
• banked $50 ---> this would give p + 50 as I have more money in the account
• doubled my money ---> would give 2p which means two times p
• spent $q ---> p - q
