# Year 6 algebra objectives

Just brushing up on subject knowledge in advance of teaching this topic but I am finding it difficult to distinguish between the objectives:
• find pairs of numbers that satisfy an equation with two unknowns
and
• enumerate all possibilities of combinations of two variables
Can someone help me by explaining what is the difference between the objectives other than the second one requires 'all possibilities'.

Thanks

Hi,

I would guess it's something like this:
• find pairs of numbers that satisfy an equation with two unknowns
So, take 2t+5 = p

The children could then find pairs of numbers that satisfy that equation. So, if t=1....p=7, or if t=2...p=9 and so on.

For this:
• enumerate all possibilities of combinations of two variables
I'd say it's things like the classic flag colouring activity. Ie how many different ways are there of colouring a flag with 2 colours. Or (and this came up in a sample test today), 'Fred has 2 coins. He flips one and it lands on a head. How many combinations are there.'

I hope this helps.

For the second, I have also see ? x ? = 24. Find as many possibilities as you can to make this correct.
