ARE WE TALKING GOBBLEYGOOK?

NO!!
It's just the language of direction and movement.

Today we played the game 'LADYBUG MAZE' to
help us practise giving directions with 'right angle turns'.

After 'programming' the ladybug to hide behind a leaf and find her way through many mazes, we decided it would be fun to write a 'program' to help a classmate get back to their desk.


We marked a spot at the front of the room with a 'cross' and off we went!


Were we running around in circles?
NO!!!

Mrs M was AMAZED at how accurate our 'programs' were!

We all made it back to our desks and some of us discovered we could get there more quickly if we turned diagonally - we learnt that was a 45 degree turn!

Here are some of the 'programs' we wrote

and here is a movie of one of our 'programs' in action!

WE DIDN'T KNOW THAT WAS MATHS!!


To help us read and interpret maps, we have been investigating position, location and movement.

We found that to give accurate directions we not only needed to state left or right, we also needed to to understand and use the terms
* 1/4 turn
* 1/2 turn
* 3/4 turn and
* full turn


Last week, when we were learning about 'right angles', Isaac made the connection between a 'right angle' and a '1/4 turn'.

Because we thought all the 'right angles' we found around the room were different sizes, Mrs M introduced us to the measurement for a 'right angle' - 90 degrees.

As you can see from the picture, this information started a 'huge' discussion, where the boys, especially Tyler, realised that they had been using the language of angles when skateboarding. They understood that a '360',is a full turn, a 'half 360' or a '180' is a half turn but now they know that they are 'working mathematically' when skateboarding!

WHEN ARE OTHER TIMES THAT WE USE 'TURNS' AND THE 'LANGUAGE OF ANGLES' IN OUR DAILY LIVES?

PLEASE LEAVE YOUR THOUGHTS IN A COMMENT.
