Kids need to know how to count by 2s, 3s, 4s, 5s, and 10s in math. Knowing these multiples will help in multiplication, division, telling time, counting money and beyond. Learning the 2s, 5s, and 10s seems to be pretty easy for kids. The 3s and 4s are a little more challenging. But, you can sing to learn the multiples and make 3s and 4s easy too.
