A demonstration of the addition of 2 and 3 to make 5. We add things together all the time in everyday life. We see different examples of adding 2 and 3 to make 5. You can turn the numbers around and still end up with the same answer.
This clip could be played at the beginning of a lesson, before asking children to add 2 and 3 in different combinations to see if the rule is correct. Then try this again with other numbers.
