Todays maths we will focus on problem solving.

I will explain the technique we use in maths to help us solve word problems. We will then go through a couple of examples together before you complete the 2do on purple mash.

The technique we use to solve word problems in maths is called RUCSAC

RUCSAC is an acronym that we can use to remember each step we must take and in which order we take them.

Below shows what each letter stands for:

Lets use this with a few examples.

R - Read the question carefully twice!

U - Understand - What is the question asking us to do? It is asking us how many items does she have altogether.

C - Choose - We have 3 numbers and it wants to know what they are all together. This means we are going to add them so we need to use +.

S - Solve so use the column method to add:

6 + 9 + 6 = 21 (Rename the 2 into tens)

2 + 8 + 0 = 10 + 2 (Renamed ones) = 12 (Rename 1 into hundreds)

1 + 1 = 2 + 1 (Renamed tens) = 3

A - Answer - 321

C - Check answer by working your way through you answer or doing the inverse.

Lets look at another question and work through it the same way.

R - Read the question carefully twice!

U - Understand - What is the question asking us to do? It is asking us how many sails there are on 26 boats.

C - Choose - If there are 3 sails on 1 bout how are we going to work out how many on 26. This means we are going to multiply them together. We need to use X.

S - Solve so use the column method to multiply:

3 x 6 = 18  (Rename the 1 into tens)

3 x 2 = 6 + 1 (Renamed ones) = 7

A - Answer - 78

C - Check answer by working your way through you answer or doing the inverse.

Using what you know now, go onto Purple mash and complete the 2do that has been set. Mr Hindman is always on Purple Mash for you to email and ask for help.
