Will a focus on basic facts increase the speed and recall of this number knowledge so it can be applied confidently when solving addition and subtraction questions to 20?
I came into this class at the beginning of term. Reports had been written by the previous teacher with most of the class below. I felt a push was needed in understanding and recalling basic facts quickly because subitising is important.
On https://doodlelearning.com/post/subitising-what-is-it-and-why-is-it-important# I found this explanation. I have highlighted below the relevant section to my inquiry.
Why is subitising important?
Subitising is important for children’s mathematical development for many reasons:
- It helps children to understand what numbers mean or how many ‘things’ a number refers to
- It helps learners with pattern recognition
- It helps children to not over-rely on counting
Subitising is an alternative maths strategy that is more efficient when dealing with smaller numbers. It helps children to see how numbers are made up.
For example, you can make the number eight using many pairs: 1 + 7, 2 + 6, 3 + 5 and 4 + 4. By separating and combining numbers through subitising, children lay the foundations for addition and subtraction.
Children also learn an important mathematical law through subitising: it doesn’t matter in what order you add numbers together, as you always get the same answer! For example, 2 + 3 = 5 and 3 + 2 = 5.
I know from experience that students who cannot use their basic facts quickly do not move through Numeracy Stages. I also want my inquiry to give me more teaching strategies for this than I have used before.
Moving the basic fact strategy level should shift the levels across the board and to lift the students from below or well below. This inquiry may only be for 10 weeks.
