Time Project

On Monday morning we were given a challenge – build the fastest K-Nex Car! We spent the morning building cars in groups and then we had to find out the fastest. We had to think about how to work out the speed. We eventually worked out that we needed to know the distance something has travelled and how long it took to go that distance. We could then work out the speed. Speed = distance/time.

We watched a video of how the police use this to work out if cars are speeding. You can watch the video here.

Square It Up!

We had this problem to do in class today –

“You need six drinking straws the same length. Cut two of them in half. You now have eight straws, four long and four short. Arrange the straws to make 3 squares all the same size”

We worked in pairs to try and solve the problem – it wasn’t easy but most people managed to find a solution.

You could try this problem at home – can you see if you can solve it by having no straws sticking out the side this time?

Guess my number

In maths today we played a game of ‘Guess my Number’. We had a large number (up to hundreds of billions) stuck on our back and we had to guess the number by asking other people questions that they could answer only yes or no to. E.g. is the hundreds of millions digit more or less than five? Is the tens of thousands number odd or even etc. We had a lot of fun and in the end everyone managed to work out their complete number.
