Maths, Matti Hemmings and Friction

Our assembly this morning was a Bike It assembly and Matti Hemmings demonstrated his BMX skills to inspire us to ride our bikes but also to try to be the best we can be at anything we want to do.

We then went back to class to do some maths! We have been looking at formal written methods for division (or the bus stop method). We began by thinking about the order we need to divide and the value of each digit we were looking at. Some of us found using place value counters and frames helpful to see which ‘left over’ numbers needed to be exchanged – the hundreds to tens and tens to ones – and which ones are remainders – the ‘left over’ ones have to be remainders.

In the afternoon it was our turn to have a workshop with Matti Hemmings –  a professional BMX rider and world record holder! He taught us some stunts

and explained some of the forces acting on his bike; especially the effects of friction.

Science It just so happens that in science today we were investigating friction and had to find out which materials would be best for a brake pad on one of Oak’s tricycles.

We will share our findings later in the week.

The rubber block was the best material to use because it created the most friction. We were surprised by the silk result as we thought it would take a while to stop the wheel as it was smooth but it didn’t. We watched a video clip that magnified materials and then we thought that silk would have lots of tiny bits that would cause friction. We also noticed that all of the materials were hot after our experiment and the rubber was the hottest.

  1. What a busy day it has been in Lime (C) Class – division, BMX stunts and science too!
    I think Matti Hemmings has inspired everyone in school – a day to remember!
