I have been running a tuition business now for over 4 years. We have children ranging from 5 years to adults needing support with their Maths, and other subjects.
When teaching maths, I have found that our students are reliant on using methods that they are learning in school, with no understanding of how or why the method works. This frustrates me because my job and every maths teacher's job is to develop student's understanding of mathematical concepts. My approach is to encourage students to investigate and question around using numbers.
For many years there have been study after study that advocate the use of concrete materials for helping children to make the connections between what they already know and new concepts. Unfortunately I have rarely seen this in mainstream classrooms beyond year one. I see lots of worksheets with pictures of concrete materials, like Base 10 and Numicon, rather than actually having the children use these to learn the maths. There is an over emphasis on making sure there are lots of lovely looking exercise books with written work in them. Research shows that when these materials, or resources you can manipulate, are used they are not used appropriately. Is this due to how teachers are trained? Most research talks about the need for these materials to be used in primary school, but as a teacher, who has taught in primary, secondary and further education I say they should be used with any student who would benefit from them.
I have used Cuisenaire rods to investigate how many different ways there are to make the numbers one to ten. I explained and demonstrated with one and two. I then asked a child, aged 10, to carry on. He made the graphemes for each number rather than the quantities. When he started to work with the rods, the way I wanted, he was amazed that 1+2+1, 1+1+2, 2+1+1, 2+2 and 1+1+1+1 all made 4 and then wanted to see the combinations for the other numbers.
In another lesson, I used some dominoes and asked the student to group them so there were eight dots in each group. She needed to keep counting the dots because she didn’t recognise the dot patterns or the combinations of dots that made totals. The task did not contain any domino tiles with a total above 6. The actual task was to arrange the 10 domino tiles into a square with a total of eight dots on each side. We didn’t get this far.
A 7 year old who can real off his times tables and tell me equivalent fractions struggled to make square number sequences. I had him make them out of counters. I decided to do the same task with a 14 year student. Her confidence with maths was very low and she did not have a fluency with any calculations yet. However she loved the task today and was able to verbalise the concepts she was learning and talk about connections to previous school lessons, she had had but not understood. The notations on the table were her thought processes when finding cubed numbers.
The benefits of using these resources are:
- Student have processing time while carrying out the task,
- they ask questions or talk about their thinking while working,
- They have a memorable lesson
- They make new connections
- and they stay focused and on task.
