Tripling means: add the number together three times.
Example: the triple of 4 is 4 + 4 + 4 = 12
The filled in number shows the answer.
Example
4+4+4=12
What does this exercise practice?
Tripling trains adding equal addends and prepares for the times table with the 3.
Common pitfalls
Children sometimes forget one of the three addends. Calculating in steps helps: first 4 + 4, then + 4.
How to practice at home
Three children each get 3 candies, how many is that altogether? Tripling becomes very concrete this way.
