Problem Solving

Every week, we try to find the answer to a maths problem, which is on our problem-solving wall. We also use our maths eyes to identify the maths all around us.

*Remember, there are lots of different strategies we can use to help us to solve a problem:

–         Simplify the problem

–         Use concrete materials

–         Draw a picture

–         Use computation

–         Act it out

–         Find a pattern

–         Guess and check

 

Take a look at our problem for this week:

Well done to everybody for their hard work on problem solving, it is great to see such enthusiasm!

 

A flight to Brazil normally costs approximately 968 euro.

During the World Cup, the flights have been increased to 1,900 euro.

How much more would it cost for 2 people to fly to Brazil during the World Cup, than at any other time of year?

 

We have also been working hard at creating our own maths problems, based on different topics. Take a look at some of them:

Problems based on the Six Nations championship

 

 

Problems based on the journey to school
