Problem Solving

Good morning all!  I hope you have all had a lovely few days enjoying the sunshine and are rested and ready to learn!

Today I have a problem that can be solved by using strategies we have covered before in class.  You could draw a diagram, make an organised list, work systematically or use trial and error.  Whichever method or methods you choose please try to write down and show how you worked out your answer.  As I’ve said in class, I am interested in the strategies we use in problem solving – and we often use smaller numbers in order to help us focus on that.

There are three problems to try.  The second has many possible solutions – how many can you find?  You can try any or all of the problems and I look forward to seeing your solutions!

Problem One – Heads and Feet

On a farm there were some hens and sheep.

Altogether there were 8 heads and 22 feet.

How many hens were there?  How many sheep?

 

Problem Two – Noah’s Ark

Noah saw 12 legs walk by into the ark.

How many creatures could he have seen?

How many different answers can you find?

Can you explain how you found out these answers?

What if Noah saw 18 legs?

 

Problem Three – More Heads and Feet!

On a farm there are chickens and sheep.

I count 48 heads and 134 legs.

How many chickens and how many sheep are there?

 

Good luck and remember you can email me, contact me on Teams or leave a comment here on the blog!
