# Maths observation lesson year 6

Can you help? My observation this term is maths. We need to focus on Ma1 as we have spent so long going over revision for SATS, we have done very little in the way of investigations and problem solving.
Head wants to see a lesson that links to the maths framework (which I don't currently plan from) and also to our topic, which this term is Islands. I want to do something fun now that the SATs are over. I have very mixed ability class ranging from 3C to 5A!
I had in mind some sort of out doors treasure hunt with and islands theme but I can't see how it will fit in with MA1. I also had the idea of setting a scenario of being ship wrecked on a desert island and having to solve various problems, with children working together in groups. Had thought along the following lines:
Having a small supply of fresh water and having to work out how long it would last for the number of people stranded (fine for low group but too easy for HA)
Working out area of shelter that could be built from materials available (low group would have no idea).
Collecting fire wood and playing with it before you start to build the fire - when you arrange it into groups of four you have 2 left over, when you arrange it into groups of....etc
You find a banana tree but can't reach the fruit. You have some large stones to make some steps. first step uses 1 stone, second step uses 3, third step uses 6....less able could be asked how many stones would be needed for x number of steps (they could draw it out) More able could be asked how many stones would be in the Nth step.
Each morning you see turtles on the beach. On the first day you notice 3 turtles, on the second day you see 5, on the 3rd day 8. You start to notice a pattern (less able what is the pattern - give them diff no of turtles with straight forward rule) How many turtles would you see on Nth day.
I need some inspiration to think what I can do with these ideas to make the lesson fun - any help would be much appreciated.

Good morning
My advice would be KEEP IT SIMPLE. There are loads of AT1 activities available on the web.....just 'adapt' them to an island theme. There is a freat book published by the DFES (as it was back then) with maths AT1 problems in it. The title escapes me but its blue and yellow. I have a copy at work if you need the ISBN forwarding.
Remember, the focus, although topic linked, needs to be on the maths work. Progression is important, ensuring that the children all do something that is both manageable and challenging. Also remember, you are judged in a lesson observation on 'How much have the children learnt today' and 'What are the next steps' - i.e. don't try to cover too much in one lesson.
Hope this helps.
Best Wishes

Thanks Adam, good advice! I think the ideas I had in mind were too complicated, but I wanted to do something the kids will enjoy. I'll think again!

Have you had a look on the nRich website? There's a plethora of problem solving activities and puzzles, each at different levels of challenge.

I'd start by finding an interesting investigation, and then only think about how you can "twist" it into an island project after that.

Treasure island, find the value of each treasure?

Weighing creatures found on your island?

Haven't thought of a link for this one. Works more efficiently (e.g. finding the area) if you only use straight lines and right angles rather than diagonals, as they can concentrate on the investigation without making mistakes when calculatinga rea.

This would be interesting. On your new, uninhabited island, each member of our class builds a house, and a road connecting it to every other house. How many roads are needed? Start by experimenting with 3, 4 houses drawn. Encourage children to see the pattern/order of drawing and use this as a means of calculating the whole class.

Thanks littlerussell you're a star! I'll check out those links - much appreciated.
