Number Bonds and Place Value
One of the most important starting points in numeracy is to learn and understand the relationship between numbers. Children are taught number bonds - pairs of numbers that make up another number. This gives a solid foundation to build upon when tackling more complicated sums. Once a child has learnt the number bonds to 10, they can quickly grasp that if 3+7=10, then 13+7=20 and 30+70=100.
Another key element to progressing well in numeracy is to have a good understanding of place value - the value of a digit depending on its place, or position, in the number. Each place has a value of 10 times the place to its right. To understand place value, children are taught the number sense behind groups of 10, moving from viewing 'ten' as 10 units but also as 1 ten. This starts with partitioning the teen numbers, i.e. 15 is 1 ten and 5 units. As the children progress to working with larger numbers, the place values for hundreds, thousands and beyond are introduced.

I've written summary sheets for number bonds and place value, I wasn't sure whether to put them in their own 'button' but I think they are key areas the children need to understand to give a good start in maths before moving on to the other operations I have done sections for - and perhaps not all parents will know what number bonds are (I know I didn't when it was written in my son's Reception report in the 'I need to work on' section). These are in Word so can be edited if necessary.

I couldn't find any example videos on You Tube, not sure there really is anything we can do for a video clip on these subjects?
