Use facts and procedures to solve simple problems.
Maria bakes cakes and sells them in bags.
She uses this formula to work out
how much to charge for one bag of cakes.
Cost = number of cakes &times; 20p + 15p for the bag
How much will a bag of 12 cakes cost?
1 mark
Olivia buys a bag of cakes for &pound;5.15.
Use the formula to calculate how many cakes are in the bag.
U3
Use facts and procedures to multi-stage problems
x stands for an odd number. y stands for an even number.
Look at the expressions below. For each expression, tick to show if it is odd or even.
The first one is done for you. (TIP: Remember Numicon, or try some examples
odd
even
x+y
x + 2y
2(x + y)
xy
x +y

Use facts and procedures to solve more complex problems.
A bar model may help with this question.
k, m and n each stand for a whole number.
They add together to make 1500
k + m + n = 1500
m is three times as big as n.
k is twice as big as n.
Calculate the numbers k, m and n.
