People with number sense can use numbers flexibly. When we want to multiply seven by eight, we may have memorized our times tables and know that it is 56. But what if we forget? Someone with number sense would also be able to work out that seven times seven is 49 and then add seven to make 56, or they may work out 10 sevens and subtract two sevens (70 – 14 = 56). In this webinar, we looked at research about number sense, some promising practices and how digital technology can support the development of number sense.
