Ready For Addition and Subtraction?Before starting to memorize facts and solve equations like 5 + 4 = , students should have started to develop their sense of number. Having learned counting numbers and being able to associate these with groups of objects which they can compare using terms like “more”, “less”, “same”, they begin modeling addition and subtraction by manipulating groups of objects; joining them together, taking some away. You will find more on this here. 

Number BondsNumber Bonds promote a way of thinking about numbers as being made up of different pairs of components. For example, 5 can be made up of a 1 and a 4, or a 2 and a 3. Thinking of numbers this way, rather than as a grouping of so many ones, helps greatly when developing and applying strategies for mental calculation. There is more on number bonds here. 
Making 10 StrategyOne of the first encounters students have with numbers above 10 is when they try to add two singledigit numbers. This is often the first time they have to deal with our place value system. It can be a big step from adding 7 + 2 to solving 7 + 5 and making this step requires strategies such as making 10. You will find more on this very important step here.
