A brief history of numerical systems - Alessandra King

All civilizations had to deal with expressing ever larger numerical quantities and they all faced the same issues. A look at the different ways humans across the planet and across the ages handled this challenge is fascinating. Among the many accounts of this long intellectual adventure, a couple are particularly readable and useful for our ends: Steven Strogatz’s section in his book “The Joy of X", excerpts of which are available online, and the article “Historical Counting Systems” in the book “Math in Society” by Lippman (Pierce College) which also provides clarifying examples and practice exercises. This fun video is also an amusing yet clear introduction to the origin and development of number systems.

A Math Framework for Multiple Grade Levels. As a K–12 district math coach, I travel to 67 classrooms and participate in math instruction at different grade levels.

A Math Framework for Multiple Grade Levels

Traveling outside of my school district, I’ve communicated with many pre-K through university math educators in person, on campuses, at conferences, and through social media. I’ve encountered rich math experiences at the secondary level, but found that they could not easily be transferred to primary classrooms. Likewise, I’ve experienced some highly effective practices in primary classrooms that would be difficult to implement in secondary settings. And I’ve noticed that elementary teachers generally converse with other elementary teachers and secondary teachers most often converse with one another. So I developed an activity—a series of animated PowerPoint slides called Splat! The Lessons There are 50 free, downloadable Splat! A Maths Dictionary for Kids 2014 by Jenny Eather.

Mr So's Classroom: Using coding to teach mathematics

I feel that it will be a skill that students need in the future. I know that this may cause some stir in many of you but here is my reasons: 1) Though I do agree with who knows what the future may hold, I do believe that this is a skill all kids will need. At one point in time no one knew how to read. In fact it was only geared to the clergy because they had to read the bible. 2) Coding does more then just teach programming skills. 3) Most kids if not all, love to code. 4) Coding teaches logical order and research skills.

Squashy Boxes*

Squashy Boxes enable children to quickly generate 'random' numbers. They are a simple but effective tool for practising a range of rapid recall and mental calculation strategies. Squashy Boxes are easy to make, 'pack flat', have hundreds of uses and are easy for children to manipulate; children can also store them in their own drawers or book bags.

This downloadable pdf file* includes templates for six Squashy Boxes (plus a blank template) together with extensive teacher notes and ideas for maths activities for both Key Stage 1 and Key Stage 2 children. Please note: mathstick boxes have been specifically designed to reduce the occurance of duplicate numbers - it's not just a random selection! Theconversation. New research has found some teachers mark boys' primary (elementary) school maths tests more favourably than girls, impacting girls' uptake of advanced mathematics and science subjects in high school.


Entrance rates into maths and science degrees at university level can also be traced back to the impacts of teachers' gender bias in primary school. Higher levels of mathematics and science education have been linked to greater employment opportunities and higher earnings, meaning a primary teacher’s attitude towards maths can have a serious impact on a child’s future success. Teachers assume boys are better at maths The researchers followed nearly 3000 students from 6th grade to the end of high school. As a measure of teacher bias, they compared school 6th grade test marks given by teachers who knew the students' sex, with external test marks for the same students, but with no identifying characteristics provided.
