When you're a maths teacher with a baby, your friends know what to buy for them.
Two children's books: 'Under the Sea 1, 2, 3' by Frané Lessac and 'Pythagorean Theorem for Babies' by Chris Ferrie and Mike Ziniti.

Latest blog post: 'Thinking About Perpendicular Bisectors' looks at teaching compass and ruler constructions for undertanding by breaking it down into small steps.

A horizontal line with six perpendicular lines. There is a large arc made from placing a compass at the right edge of the horizontal line. There are six arcs of increasing size, made from placing a compass at the left edge of the horizontal line.

Here are some patterns that can be made using "circle(radius, angle)" to draw arcs. In this case the angle was 120 degrees. #MathsChats
Flower-like object with 18 petals, joined at the centre. Each petal is made from two arcs of a circle joined together at either end. Each arc is one third the circumference of a circle. Each petal is a 20 degree rotation of the previous one, around a point at the centre of the flower. Flower-like object with 12 petals and an empty space in the centre. The petals are made from 12 overlapping arcs, where each arc is one third the circumference of a circle.

Here are a couple pictures that are not included in the blog but can be made by using the same commands as the ones it covers. In this case, the length of the lines vary by being set as equal the loop number.

A spiral shape made squares of increasing size, rotating around a single point at one of their vertices. A hexagonal spiral shape. Starting from the centre and working outwards, the length of each line is 1 unit longer than the previous one and makes an angle of 120 degrees.

After reading Matt Parker's book about mathematical errors on the train to London, I was inspired to visit the "Walkie-Talkie" building while here. Initially, its parabola-like shape caused its windows to concentrate reflections of the sun and slightly melt nearby cars. #mathschat
20 Fenchurch Street in London - often nicknamed the "Walkie-Talkie" building.

Geometric pattern made from 36 overlapping squares. The squares rotate around a single point in the centre, where every square has one of its vertices at that point.

New blog post: 'Taxing Tasks with Turtles'. Looks at a selection of geometry problems and investigations that can be explored by using a small amount of coding.
