I like ratios. All the introductory skills are performed using whole numbers. Therefore, I think this is a topic/concept that should be taught in primary schools. I have found that, when properly introduced, children adapt quite well to this kind of thinking.
I start by calling it sharing. Every child is familar with the concept of sharing … one for me, one for you, two for you … and can predict how many items each person will have after a given number of cycles. They do this when dealing cards, for example.
Many students have watched concrete being made. When I explain how a labourer will have a pile of blue metal (aggregate), a pile of sand, and a supply of cement powder, and how they load the mixer, most of them readily understand the process and can calculate what a labourer would need to do for a double load. Most can even suggest two methods/sequences for loading the mixer.
In my opinion, it is vital that students learn to set their work out clearly in columns and that, except for the most elementary problems, the first line should consist of column headings. You will see more of this when I begin adding material here.
Rates compare measurements of ‘like’ quantities, for example two distances or two times or two money amounts. They are normally written side-by-side separated by colons (:). All will be revealed as I add material to this page!
Our daughter Angelina was home schooled and from the start did not like maths. Over the years I have battled through, trying 5 different programs along the way. Angelina was surviving but not enjoying the journey but, when it came to algebra, the future looked dim. A friend recommended Graeme to me as her three sons had been tutored by him. She could not recommend him more highly. My daughter has just finished year 12 maths and did very well, thanks to Graeme (that would be an understatement). Graeme has a love for his subject and a genuine interest in his students. Graeme seems to meets his students where they are and tailors the lessons to meet their individual needs and interests. Graeme not only explains concepts clearly, but we all found him an interesting, knowledgeable and humble man. We are extremely happy that Graeme was recommended to us. Now our daughter is looking forward to uni with a grateful heart. We also could not recommend Graeme more highly.
