I am going to give you an expression in words.
You are going to write the expression using symbols and letters.

4. Task One
Choose a card set.
Match the cards by numbering them or drawing arrows to link them together.

5. Card Set A n + n + n 4f Three lots of n add two n + 2n + 2 2f
Using arrows or numbers match up the equivalent expressions and the meaning in words.
Use the blank cards to write your own meaning in words.
n + n + n 4f
Three lots of n add two
n + 2n + 2 2f
four multiplied by e
c + c + c + c 2d
two multiplied by d
2d + d 3d
f add f add f subtract f
d + d + d - d 4e
d times three
e + e + e + e
3n + 2
f + f + f - f 4c
f + f+ f + f 3n

6. Add one to n then multiply by two
Card Set B
Using arrows or numbers match up the equivalent expressions and the meaning in words.
Subtract n from two

Add one to n then multiply by two
Subtract two from n
Multiply n
by two
Add n to n
n + 3
n - 2 2n 3n
n + n
2 (n + 1) n 2
n - 1 n2
n + n + n
2 – n 3
2n + 2
