# site redesign

I haven’t posted on the blog in 2015 - which there’s really no excuse for.

I have loads of ideas for posts so to kick things off the site has been redesigned and is now hosted on GitHub Pages. It’s gone from this…

… to this …

It’s still work in progress, but it’s getting there.

Some of the resources have been reorganised behind the scenes, so I hope this doesn’t cause anything to break. This is to get things ready for the presentations section of the site.

# equivalent fractions

Having read a superb post about the Singapore Bar Model from William Emeny I thought I would share these diagrams for introducing equivalent fractions:

Students identify that $\frac{5}{12}$ of the diagram is shaded blue.

With each square now shown in two pieces, they can then see that $\frac{10}{24}$ is shaded and that this is equivalent to $\frac{5}{12}$.

Once they are happy with the second step then there isn’t much of a leap to showing that $\frac{20}{48} = \frac{10}{24} = \frac{5}{12}$.

Whilst these diagrams are given in a slightly different format to the bar model, the idea is similar.

## presentation

Here is a small presentation that may be useful.

# magic names

Here’s a starter inspired by a problem in the excellent Cabinet of Curiosities book by Ian Stewart.

The names of 10 students are displayed around the diagram. Start from ‘Mister Mort’ and move clockwise along one edge for each letter as a name is spelled out. You should finish on that person’s name.
