You have 20 counters in your hand.
Each counter is either purple or black.
Copy and complete this table which shows some
combinations you might have.

You are choosing 12 logic blocks for a game.
They have to be triangles or circles.
Design a table like the one in ITJ to show all possible choices
if you choose more triangles than circles.
Explain your choice of letters.
You have a box of counters. ed blue green yellow white
The number of each colour is shown
58 71 64 81 49
in this chart.
I If red and blue counters are combined, they will total 129.
You could write this as an equation: r + b = 129.
Show that you can write 9 more equations
like this by combining counters of 2 colours.
RuLE: 'r + b = 129' is the same as 'b + r = 129'.
