In this video lesson children learn the meaning of the symbols + and = (plus and equals) and write simple addition sentences using them. It is most suitable for kindergarten math but can be used in early 1st grade also.
I also include sums with zero as that is an important concept (for example, 0 + 2 and 0 + 0). The lesson is easy and straightforward and lets kids think before I say or write the answers. Mathy my mascot mammoth draws surprise pictures for one problem. :)
